Comment: Several commenters pointed 
out that the Supreme Court had found the listings to be inherently 
incomplete (by virtue of being a finite list) and always in danger of 
being out-of-date. Therefore, in order to comport with the Supreme Court's 
analysis, and to facilitate and encourage use of the functional 
equivalence principle, the commenters recommended that the regulations 
should more directly acknowledge the limited role and shortcomings of the 
listings.
Response: We did not adopt the 
comment. As we discuss below with regard to the comments on functional 
equivalence (final § 416.926a), the Supreme Court made these 
statements in the context of examining the propriety of a listings-only 
test of disability for children. The point of the analysis was to show why 
we could not establish a standard of comparable severity by confining our 
adjudication to the listings, and why we were required to devise another 
step beyond the listings in order to satisfy the comparable severity 
standard in the statute. The Court did not state or even imply that we 
should alter the method of adjudication at the listings step, or that we 
should be required to acknowledge any shortcomings of the listings. (As we 
explain later, we did improve our method of adjudication under the 
listings in an effort to improve our entire disability evaluation process 
for children even though this was not a requirement of the 
Zebley decision.)
Moreover, based on our operating experience since implementing the prior 
rules, we do not believe that it is necessary to “encourage” 
the use of the functional equivalence policy; our adjudicators are well 
aware of its existence and how to apply it.
Comment: Three commenters called on 
us to update the Listing of Impairments for children's disabilities, 
noting that the listings for some conditions are already out-of- date, 
that others are incomplete, and that others are lacking. One commenter 
stated that the current listings did not include fetal alcohol syndrome 
(FAS), acquired immunodeficiency syndrome (AIDS), or human 
immunodeficiency virus (HIV) infection that is not AIDS. Another commenter 
said that the listings did not include AIDS, Down syndrome, muscular 
dystrophy, infant drug dependency and FAS. One commenter pointed out that 
the Supreme Court had stated that the listings did not include spina 
bifida. 110 S.Ct. at 893, n.13. This commenter said that the rules should 
be amended to provide an expedited procedure for making additions to the 
listings. The commenter suggested that such a procedure might be 
established by providing in the preamble to the listings that “the 
Secretary, or the Secretary's delegate may, in his or her discretion, add 
to the listing in concert with a petition by interested public citizens or 
groups.” Another commenter called for a formalized mechanism to 
review and modify listed impairments based on current medical knowledge, 
stating that such an approach would be consistent with the current rules, 
which say that the listings are not intended to be self-limiting.
Response: We have not adopted these 
comments. We are in the process of revising the listings for both children 
and adults; however, these revisions go far beyond the ambit of the 
present rules and will be proposed through normal Administrative Procedure 
Act (APA) rulemaking procedures. We have published final revisions of both 
the multiple body system listings, which includes Down syndrome, FAS, and 
other such disorders, and the childhood mental listings (55 FR 51204 and 
51208, December 12, 1990). We have also published NPRMs proposing to 
update the listings for endocrine and multiple body system disorders and 
to add rules for the evaluation of immune system disorders, including 
human immunodeficiency virus (HIV) infection (56 FR 65702, December 18, 
1991), adult mental disorders, which may be applicable to children in 
certain circumstances (56 FR 33130, July 18, 1991), the respiratory 
listings, including the childhood asthma listing (56 FR 52231, October 18, 
1991), and the cardiovascular listings, including the childhood listings 
(56 FR 31266, July 9, 1991). We have also published in the Federal 
Register, 
Social Security Ruling 91-8P, 
which addresses our procedure for the evaluation of HIV infection and 
specifically addresses the manifestations of the infection in children (56 
FR 65498, December 17, 1991).
At the time we received the comments about Down syndrome and FAS, there 
were specific listings for both impairments, in Listing 110.06 (for Down 
syndrome) and Listing 110.07 (for FAS). The second paragraph of section 
110.00A.2. of the listings explains that FAS is an example of an 
impairment that should be evaluated under Listing 110.07; by inference, we 
also include infant drug dependencies under that listing. (See 55 FR 
51204, December 12, 1990.) Although the diagnosis of 
“muscular dystrophy” is not specifically stated in the 
listings, Listing 110.06, “Motor 
dysfunction due to any neurological disorder,” describes the 
impairment. Similarly, our listings (though not using the exact name) 
actually have long included spina bifida at Listing 111.08, 
meningomyelocele, which is the technical, anatomical description of what 
can be a serious, listing-level result of spina bifida.
Finally, we do have a formal mechanism for updating the listings, and our 
mechanism is consistent with what the commenter recommended we do.
Comment: One commenter observed that 
“the individual condition listings carry some elements of physical 
functioning; however, they provide no generic view of physical disability 
nor are they consistent across condition groups.  A person with less 
disability may be determined eligible because of the idiosyncracies of one 
specific disease compared to another.” Another commenter 
recommended that, to facilitate functional equivalence determinations, all 
the childhood listings be revised to include both medical and appropriate 
functional considerations, as was done with the mental disorders listings 
in 112.00 of the Listing of Impairments.
Response: Although the first comment 
was not entirely clear, we believe that the commenter was saying that some 
listings have criteria that are less severe than the criteria in other 
listings, especially among the physical listings. Although it might be 
debated whether such comparisons are possible or even necessary, any 
differences are insignificant because a claimant may be found disabled 
using the policy of functional equivalence, and because there is another 
step beyond the listings step at which children whose impairments do not 
meet or equal listings can still establish that they are disabled. 
However, as we revise each of the listings sections, we will consider 
including appropriate functional considerations, as suggested by the 
second commenter.
Section 416.924(g) 
Basic Considerations
Comment: One commenter wanted to 
know the meaning of statements in the preamble and in § 416.924a(b) 
of the prior rules (final § 416.924(g)) with regard to determining 
the validity and reliability of formal testing. The commenter quoted 
preamble language 
(“* * * the results of standardized testing should be 
consistent with the remainder of the record * * *” (56 FR at 5538)) 
and asked whether it means that if the child appears to be functioning at 
a level higher than the score would suggest, SSA will disregard the 
scores.
Response: We do not disregard any 
test scores that we receive in a child's claim. We believe the meaning of 
final § 416.924(g)—which is also nearly identical to language 
in 112.00D of the childhood mental listings—is clear. It says, in 
pertinent part, that 
“* * * any discrepancies between formal test results 
and your customary behavior and daily activities should be duly noted and 
resolved.” We do not disregard any relevant medical or nonmedical 
evidence, including test scores, but neither do we disregard apparent 
conflicts in the record when we consider that evidence in conjunction with 
the rest of the evidence. We take whatever steps are necessary (e.g., 
recontact with the testing source for input on the validity of the test 
scores, or recontact with other medical or nonmedical sources to find out 
more about the child's actual ability to function) to determine whether 
there really is a conflict, and to resolve the issue.
Comment: Three commenters noted that 
although the proposed final rules show an appreciation of the importance 
of obtaining information about a child's functioning from nonmedical 
sources such as parents, teachers, and other caregivers, the regulations 
do not require us to obtain records from these sources. The commenters 
feared that unless we explicitly acknowledge this responsibility in 
regulations and give instructions for obtaining these records, we may not 
fully develop the child's claim. One of the commenters was particularly 
concerned that the regulation does not strongly recommend that 
adjudicators obtain details on the child's health from the child's 
personal physician; the commenter recommended that we include a provision 
requiring the use of this information. Amending language on these issues 
was suggested for § 416.924a(b)(2) of the prior rules (§ 
416.924(g)(2) in these final rules).
Response: Final § 416.924(g) 
clearly states that we will consider nonmedical evidence in any case in 
which it is relevant. Because a significant number of children are found 
to be disabled based solely on medical evidence, it is not necessary to 
require the development of nonmedical evidence in all cases. We did not 
adopt the comment that we should add language to these rules requiring our 
adjudicators to obtain evidence from the child's treating physician 
because, shortly after the close of the comment period for these rules, we 
published final rules in the FEDERAL REGISTER which accomplish the same 
goal. Pursuant to § 416.912(d) of the final rules, 
“Standards for 
Consultative Examinations and Existing Medical Evidence,” published 
on August 1, 1991 (56 FR 36932), we will make every reasonable effort to 
develop a complete medical history for at least the 12 months preceding 
the month in which the application is filed, before we make a 
determination that a child is not disabled.
Section 416.924a 
Age as a Factor of Evaluation in Childhood Disability
Comment: Three commenters 
recommended that we replace the last clause of § 416.924b(b) of the 
prior rules (final § 
416.924a(b))—“however, we will not apply 
these age categories mechanically in borderline situations”—with 
different language. One commenter suggested that we use language from the 
preamble which would remove the reference to 
“borderline situations” and emphasize that each case must be 
evaluated on its own merits. The other two commenters echoed these 
comments but suggested their own replacement language. One commenter 
thought that rigid application of the age categories carried the greatest 
risk of any provision in the childhood disability rules of being 
mechanically applied, which would work to the detriment of at least some 
children.
Response: We responded to the 
comments by deleting the statement and in the general reorganization of 
the rules.
The clause in § 416.924a(b) of the prior rules was almost identical 
to the last sentence of § 416.963(a), the rule setting out the adult 
age categories, the language of which we had adopted for consistency. 
However, we emphasize in these rules that the age categories in the 
childhood rules have a different purpose than the age categories in the 
adult rules. In the adult rules, assignment to a particular age category 
can be dispositive of the issue of disability. This is because, under the 
medical/vocational rules and guidelines in appendix 2 to subpart P of part 
404, it is possible for an adult who is in a lower age category (e.g., a 
“younger individual,” aged 49) to be found not disabled, 
while another adult, with the same residual functional capacity, 
education, and work experience but who has reached the next age level 
(e.g., a person who is 50 years old and, therefore, 
“closely approaching advanced age”) might be found 
disabled.
The childhood regulations, however, do not contain rules like those for 
adults in appendix 2. The childhood age categories function as descriptive 
devices; that is, they are a convenient way for us to describe functioning 
and the kinds of evidence we would expect to need for children of 
different ages (in § 416.924d), and to set down guidelines for 
determining disability (in § 416.924e). Moreover, all of the 
guidelines in final § 416.924e regarding what may constitute a 
disability in the different age categories are set at the same level of 
severity; they merely use different descriptors to describe 
age-appropriate assessments of disability. Therefore, there is no 
disadvantage (or advantage) to a child's being “assigned” to 
one age category or another.
We believe that the general reorganization of the final rules also makes 
this clear. By moving § 416.924a(c) of the prior rules, 
“Terms used 
to describe functioning,” into final § 416.924b, 
“Functioning in 
children,” we have incorporated into the basic rules on the 
assessment of functioning in children the principle that the various 
descriptors of functioning (activities of daily living, developmental 
milestones, etc.) can be used across age categories where appropriate. 
Thus, for example, the final rule at § 416.924b(b)(3) on the 
assessment of functioning provides that, 
“[o]rdinarily, activities of daily living are the most 
important indicators of functional limitations in children aged 3 to 16, 
although they may be used to evaluate children younger than age 3.” 
This is also a basic principle in the listings that use age categories. 
For instance, in the preamble to the final publication of the childhood 
mental disorder listings, we stated:
This is not to say that children who are older than 1 cannot be found to 
have an impairment which is equal to the severity of listing 112.12. As we 
emphasize throughout these responses, any child who does not have a listed 
impairment can still be found disabled if he or she has an impairment or 
combination of impairments that is equivalent to any listed impairment. 
Children older than 1 whose impairment manifestations are identical or 
sufficiently similar to the requirements of 112.12 could, in certain 
situations, be evaluated using the new listing (55 FR at 51227).
The reason we did not adopt the suggestion to incorporate our language 
from the preamble to the prior rules is that it still implies that 
assignment to a particular age category can somehow matter in the ultimate 
decision of disability. On balance, we think that the better course of 
action is to delete the idea and reorganize the rules, as discussed 
above.
Comment: Three commenters objected 
to the provision in § 416.924b(c) of the prior rules (final § 
416.924a(c)). That section states that we compute a corrected 
chronological age for premature children until the prematurity is no 
longer considered a significant factor, generally around age 2. The 
commenters argued that the provision appears contrary to the statute. They 
said that, although a pediatrician may need to adjust a child's 
chronological age to determine whether a developmental delay is permanent, 
the law does not require that a child have a permanent impairment in order 
to establish disability. The commenters also thought that using an 
adjusted age could result in incorrect disability determinations. They 
gave an example of an 18-month-old child, born 10 weeks prematurely and 
with mild mental retardation, who would be found to have an impairment 
that meets the childhood mental disorder listings if she were found to be 
functioning at less than 2/3 of her chronological age in two of the 
paragraph B criteria of the childhood mental disorder listings (i.e., if 
she were functioning at a chronological age of 12 months). However, the 
commenters stated that if we were to adjust her chronological age to 
correct for her prematurity, her “adjusted” age would be 15 
1/2 months and she would not meet the listing criteria.
The commenters also thought that correcting a child's chronological age 
denies children who were premature an individualized assessment of their 
impairments, although they did not explain why they thought this.
Two of the commenters submitted identical recommendations for language 
changes to § 416.924b(c)(3)(i) of the prior rules (final § 
416.924a(c)(2)(i)). The changes would have indicated that we correct 
chronological age: (1) only when there is a question whether any delay was 
caused “solely” by prematurity that is expected to resolve; 
(2) only in the first year of life, and (3) only when we cannot separate 
out other causes for the delay. The suggested provision would also have 
provided for the payment of benefits retroactive to the date of 
application if it later developed that a disabling condition was present. 
In a similar vein, the third commenter recommended that if we were to use 
a corrected chronological age at all, we should limit it to the first year 
of life and only when we cannot identify specific medical or genetic 
causes for the delay.
Response: We partially adopted the 
comments. We believe the commenters misunderstood both our intent and how 
the rules function, but we believe that the prior rule can be made 
clearer. It is not our intention in adjusting a premature child's 
chronological age to determine whether a child has a “permanent 
impairment,” nor is that the purpose of such an adjustment in 
pediatric practice. Pediatricians adjust a premature child's chronological 
age in order to make the results of their evaluations more valid and 
predictable. Such an adjustment is also more useful in planning treatment 
or intervention, and in the pediatricians' discussions with parents about 
a child's possible developmental delays. A pediatrician must be certain 
that a child is progressing physically and mentally according to an 
expected developmental channel.
In the case of a premature child, it is necessary to consider the child's 
gestational age at birth in order to know whether the child is progressing 
within a normal range of development given his or her gestational age at 
birth. If, given the child's adjusted chronological age (i.e., adjusted 
for gestational age at birth), the child's progress is not within a normal 
expected range, the pediatrician then must consider ongoing monitoring of 
the child's development and provision of intervention services. For 
example, infants usually are able to turn their bodies from a supine to a 
prone position by 3 or 4 months of age. If a child who was born 2 months 
prematurely cannot do that at a chronological age of 4 months, the 
adjustment of the child's chronological age to 2 months lets the physician 
and parents know that there is no cause for concern at that time. If, on 
the other hand, the same child at a chronological age of 6 months could 
not turn her body to a prone position, there would be cause for concern 
because the child's adjusted chronological age would be 4 months, an age 
at which the infant would be expected to be able to perform that 
developmental skill.
Our reasons for adjusting a premature infant's chronological age are 
similar to those of pediatricians. We need to know if a child's 
functioning at the time of our evaluation is age-appropriate or whether 
the child is not functioning in the way we would expect, a sign of 
impairment-related limitation. In the case of a premature infant, the only 
way to ensure that our evaluation of the child's functioning is valid is 
to take into consideration the child's gestational age at birth, and to 
adjust accordingly our idea of what is age-appropriate for that 
infant.
We must also point out that in many instances we do not have to compute a 
child's adjusted chronological age and reinterpret the evidence in terms 
of that adjustment. This is because the adjustment is made by the treating 
physician or psychologist (or consulting physician or psychologist) when 
he or she evaluates test results for assessing a child's development. The 
medical source would record the child's chronological age, the date of 
testing, the child's adjusted age at the time of testing, and the child's 
performance within a range, or at a level of functioning in various areas 
(e.g., motor, social). If the treating or consultative source's report is 
not clear about whether the child's prematurity has been taken into 
consideration, we will recontact the source to ask that question, pursuant 
to § 416.912(e) of our regulations. (See, 
“Standards for Consultative Examinations and Existing 
Medical Evidence,” 56 FR at 36963.)
However, we agree with the commenters to some extent that it is not always 
appropriate to adjust a child's age between the ages of 1 and 2. Within 
pediatric practice, there is general agreement that a premature child's 
age should be adjusted up to 12 months of age for the purpose of 
evaluating either development or linear growth, because it is very 
difficult in the first year of a child's life to differentiate the effects 
of prematurity from the effects of any possible underlying impairment. It 
is also generally agreed that for the purpose of evaluating development, a 
child's age need not be adjusted after 24 months of age because by that 
time a premature child should have “caught up” in terms of 
achieving developmental milestones. When a premature child is still 
exhibiting significant developmental delays at 24 months, it is more 
clearly discernible that those delays are attributable to an identifiable 
disorder. Within the period between 12 to 24 months of age, however, 
pediatric practice varies as the pediatrician sorts out developmental 
effects that may still be attributable to prematurity from those that may 
be attributable to a medically determinable impairment. During this 
period, pediatricians may make a full adjustment of age (e.g., deducting 
10 weeks from a child's chronological age if the child was born 10 weeks 
prematurely), or only a partial adjustment (e.g., deducting 5 weeks from a 
child's chronological age if the child was born 10 weeks prematurely), or 
no adjustment at all.
In cases of developmental delay, whether or not an adjustment of 
chronological age is made during the period between 12 and 24 months of 
age depends upon clinical judgment about many qualitative factors 
concerning the child's development and the severity of the child's 
developmental delays. The more significant the developmental delays, the 
more likely it is that no adjustment or only partial adjustment would be 
made, because the observable delays are more likely to be the result of 
underlying impairment rather than of prematurity. For instance, in the 
example provided by all three commenters about the 18-month-old child with 
mild mental retardation (i.e., mental retardation with an IQ in the 60 to 
70 range), it is not necessarily the case that a pediatrician (whether 
treating, consultative, or reviewing) would fully adjust the chronological 
age of the child. Many factors would have to be considered. For example, 
manifestations of delay in more than one area of functioning, as indicated 
in the example, tend to suggest that the child is experiencing the global 
effects of the medically determinable impairment rather than of 
prematurity. Therefore, the clinician would have to consider the 
particular nature and severity of the medical impairment(s) and the 
child's delays in order to determine whether full, partial, or no 
adjustment of age would be appropriate. We must also add again that the 
example submitted by the three commenters seemed to assume that the child 
had to have an impairment that met the listings in order to be found 
disabled; this, of course, is not the case under the new rules.
Given the foregoing discussions and the comments, we have revised the 
rules to indicate more clearly that when assessing either development or 
linear growth in premature children, we will make a full adjustment for 
chronological age until age 1; thereafter, in cases involving 
developmental delay and until prematurity is no longer a factor 
(generally, around age 2), we will decide whether to make an adjustment 
and, if so, the extent of the adjustment to be made. Our decision will be 
based on judgment, informed, of course, by the individual facts of the 
case, including any treating source opinion on the matter. Even though it 
is not the exact approach the first two commenters suggested, we believe 
that it is fair, consistent with standard pediatric practice, and 
administratively feasible. We did not adopt the first two commenters' 
suggestion that, when we have made an unfavorable decision in a case, we 
should provide benefits retroactive to the date of the original 
application if we later determine that a disabling impairment was present. 
However, the rules for reopening in §§ 416.1487 to 416.1493 
would still be applicable should the claimant reapply. In addition, the 
claimant has the right to appeal an adverse determination in accordance 
with our regulations.
Comment: A number of people 
submitted the same comment, asking us to delete § 416.924b(d)(3) of 
the prior rules. The commenters thought that the paragraph stated we would 
make assumptions about a child's “adaptability” based on age 
without individualized consideration of the effects of the child's 
impairments. Most of the commenters said that it is not true that every 
child benefits from increased adaptability as he or she grows older. Some 
commenters said that older adolescents may experience a variety of 
impairments that may render their functioning similar to that of younger 
children, and make any transition into the adult workplace exceedingly 
difficult. Advocates of children with severe physical impairments (e.g., 
cerebral palsy, spina bifida) were concerned that the general guidance in 
§ 416.924b(d)(3) of the prior rules might be applied as a presumption 
in the case of adolescents whose impairments only exacerbate the 
difficulty of assimilation into adult society as they grow older. The 
commenters said that evaluation of a child's adaptation to his or her 
impairment(s) and ability to function age-appropriately must consider the 
nature of the child's impairment(s), when the impairment(s) began, and how 
it affects the particular child.
Two commenters perceived the provision as a “double-counting” 
of the factor of age in the case of older adolescents. That is, they 
thought we make a general presumption of increased adaptability due to the 
adolescent's age in addition to considering the child's age as a factor in 
the individualized functional assessment (i.e., in terms of the child's 
performance of age-appropriate activities of daily living).
Two commenters also recommended the deletion of the last sentence in 
§ 416.924b(d)(2) of the prior rules: 
“Generally, the more global 
effect of these kinds of impairment on development diminishes with 
increasing age.”
Response: We disagree with the 
commenters, but we have clarified final § 416.924a(d) in response to 
the comments. We believe that it is a well-established and widely accepted 
principle that, given the nature of child development, impairments that 
occur during the early developmental period generally have a more 
pervasive impact on a child's functioning than those that occur later in 
life.
We did not intend the statement of this general truth, however, to obscure 
the fact that adaptability to an impairment is a highly individual matter 
regardless of one's age. For this reason, we evaluate an older 
adolescent's impairment(s) in the same manner that we evaluate all other 
children's impairments: We consider those activities, skills, and 
behaviors that are appropriate for children of the same age. It is also 
certainly true that adolescents may experience serious functional 
limitations resulting from developmental, degenerative, or traumatic 
impairments, as well as other impairments with onset later in childhood. 
Therefore, we do not “presume” that an older child is better 
able to adapt to his or her impairment than a younger child; we evaluate 
each case on its own facts.
To make this policy clearer, we have revised the opening sentences of 
§ 416.924b(d) of the prior rules (final § 416.924a(d)), and 
added a new § 416.924a(d)(1), both of which explain that these 
guidelines apply to determinations of disability, not to the assessment of 
functioning itself. New paragraph (d)(1) explains that we recognize that 
how a child adapts to an impairment(s) depends on many factors, including 
the nature and severity of the impairment(s), the child's temperament, 
adult intervention, and the child's age at onset. We then explain that 
“adapting to an impairment” means the child's ability to 
learn skills, habits, or behaviors that allow the child to compensate for 
the impairment(s) and to function as well as possible despite the 
impairment(s). Finally, we explain that our disability determination will 
consider how the child has adapted to the impairment(s) and how well the 
child is functioning, considering all appropriate factors.
Comment: Several commenters thought 
that the principle in § 416.924b(d) of the prior rules was not legal. 
The commenters said that the statute allows us to consider an adult's age 
when determining disability, but that the law has no similar provision for 
children.
Response: We disagree with the 
comments. The Act does not preclude consideration of age in childhood 
claims. Indeed, as we have already stated at the beginning of this 
preamble, the statute states very little about what the standard of 
disability for children should be, only that a child's impairment(s) 
should be of “comparable severity” to an impairment(s) that 
would disable an adult. Because the statutory standard is one of 
comparability to the adult standard, we believe that consideration of age 
is permissible under the law.
Comment: Several commenters 
discussed whether the new rules set a higher standard of disability for 
older adolescents. Five commenters, in identical language, said that the 
rule might be considered a higher standard and, therefore, be misapplied. 
One commenter said that the provision violates the spirit of 
Zebley because it sets a higher standard of 
disability for older adolescents. Finally, one commenter said that we 
treat 16-18-year-olds as if they were already younger adults, subject to 
SSA's adult claimant rules. The commenter said that we were required to do 
a full analysis of the child's functioning, using the five functional 
domains.
Response: We disagree with these 
comments. We do not evaluate the disability claims of older adolescents 
using a higher standard than we use for younger children, nor do we 
believe that these rules disadvantage older adolescents. Our rules 
recognize that adolescents begin activities that prepare them for the 
world of work, and that these activities may occur both in and outside of 
school. Specifically, with regard to older adolescents, the definition of 
disability in § 416.924(a)(3) recognizes that the functional 
abilities, skills, and behaviors that are age-appropriate for 
16-to-18-year-olds are those that are also age-appropriate for 
18-year-olds; i.e., those capacities that allow a person to function in 
the adult world. Final § 416.924a(d) provides more detail to the 
basic definition. We have established a new § 416.924a(d)(4) for 
adolescents, which clarifies principles from the basic definition of 
disability in § 416.924(a)(3) and in § 416.924b(d) of the prior 
rules, and adopts language from our manual instructions. In new 
subparagraph (d)(4)(ii) we clarify our policy that, inasmuch as 
age-appropriate functioning for an older adolescent is also that of an 
18-year-old, the disability determination for an older adolescent must be 
consistent with the disability determination we would make for an 
18-year-old with the same functional limitations. Thus, final § 
416.924e(d) further describes the work-related mental and physical 
functions that we evaluate for older adolescents.
We also do not believe that the rules violate the letter or spirit of 
Zebley. As required by the Supreme Court's 
decision, the rules provide older adolescents an additional adjudicative 
opportunity beyond the listings step to demonstrate they are disabled, 
comparable to the opportunity which is given adults. Our experience has 
shown that the rules have not been misapplied.
Finally, we do not apply SSA's adult claimant rules to the claims of older 
adolescents. Older adolescents receive the same kind of individualized 
functional analysis as all other children under these rules. When we 
perform an individualized functional assessment, we draw a profile of how 
an older adolescent is functioning by considering his or her activities of 
daily living in the applicable functional domains. We then evaluate 
whether those activities are age-appropriate. That is the same general 
process by which we evaluate the impairment(s) of a child of any age. For 
an older adolescent, once we have gathered all the information we need 
about the adolescent's activities of daily living, we construct a profile 
of his or her functioning in all of the five functional domains that may 
be affected by the impairment. Once that profile is established, we 
translate the functional information that we have into work-related (and, 
therefore, age-appropriate) terms. The profile we draw of the adolescent's 
physical abilities must enable us to determine if he or she can perform 
the basic physical demands of at least sedentary work. The profile we draw 
of the adolescent's mental abilities must also enable us to determine if 
he or she can perform the basic mental demands of at least unskilled work. 
This is not the same determination we make for adults: In an adult's 
claim, the disability determination finally addresses whether the person 
can do past relevant work or other work; a disability determination in an 
older adolescent's claim does not address whether the child can work, only 
whether the child can do work-related physical and mental 
activities.
Comment: One commenter said that it 
is important to emphasize that § 416.924b(d) of the prior rules 
provides only guidelines concerning the impact of severe impairments on 
younger children and older adolescents. It was recommended, therefore, 
that we add three sentences from the prior preamble (56 FR at 5540) to the 
paragraph.
Response: Although we did not 
incorporate the exact language suggested by the commenter, we provided two 
sentences in § 416.924a(d)(4)(ii) which have the same meaning. We 
also believe that we have addressed the comment by adding final paragraph 
416.924a(d)(1), the new paragraph that provides rules on how children 
“adapt” to their impairments.
Section 416.924b 
Functioning in Children
Comment: One commenter pointed out 
that there were inconsistencies in § 416.924(a), § 416.924a(c), 
and § 416.924e(b) of the prior rules in our use of terms to describe 
functioning at the different age levels. The commenter recommended that we 
make these various age category descriptions consistent.
Response: We adopted the comment. We 
agree that there were some unintentional inconsistencies in the rules. For 
example, § 416.924a(c)(2) in the prior rules, (§ 416.924b(b)(2), 
“Developmental milestones,” in these final rules) stated that 
“developmental milestones” are ordinarily the most important 
indicators of impaired functioning in children from birth until the 
attainment of age 6, although they might be used to evaluate older 
children, especially school-age children. However, § 416.924e(b)(1) 
in the prior rules (“How we describe functional limitations”) 
appeared to stress the use of developmental milestones only for children 
aged from birth to 3 years while § 416.924e(c)(2) in the former rules 
seemed to stress the use of activities of daily living in children aged 3 
to 6.
We have, therefore, stated in § 416.924b(b)(2) in the final rules 
(§ 416.924a(c)(2) in the prior rules) that “failures to achieve 
developmental milestones” are ordinarily 
“the most important indicators of 
impaired functioning from birth until the attainment of age 3, although 
they may be used to evaluate older children, especially preschool 
children.” This revision makes § 416.924b(b)(2) consistent 
with the guidance in final § 416.924e(b)(1), the language of which we 
have not changed. The revision also makes both sections consistent with 
our basic definition of disability in § 416.924(a)(1). Similarly, 
§ 416.924b(b)(3) now states that 
“activities of daily living” are ordinarily 
“the most important indicators of functional limitations in children aged 
3 to 16,” but that 
“they may be used to evaluate children younger than age 
3.” This makes the language of § 416.924b(b)(3) consistent 
with our statements in § 416.924e(b)(2), which is unchanged, and 
§ 416.924(a)(2) in the basic definition of disability. We have also 
added a new § 416.924b(b)(4), “Work-related activities,” 
for children aged 16 to 18, to be consistent with §§ 
416.924e(b)(3) and 416.924(a)(3). Finally, to reflect the addition of new 
§ 416.924b(b)(4), we have redesignated paragraph (c)(4) of the prior 
rules, “Domains,” as paragraph (b)(5) in the final rules; we 
have also amended the age ranges referred to in the third sentence of the 
paragraph to reflect the foregoing changes. In addition, we have changed 
the heading of final paragraph (b)(5) to 
“Domains and Behaviors” because 
“responsiveness to stimuli” and 
“concentration, persistence, and pace” are not 
“domains” but “behaviors.”
None of these revisions is intended to be a substantive change from the 
rules as we originally published them; rather, they clarify our intent so 
as to prevent any misunderstanding of our policy. The rules in final 
§ 416.924b(b) are definitions of terms we use in other rules. From 
the outset, our primary intent in including these definitions was to 
provide a common set of terms for use with the new rules and to provide 
some guidance about the kinds of evidence of functioning one might expect 
to find (or seek) for children of different ages. By using words like 
“ordinarily” and “although” in these sections, 
our intent has been to make clear that the terms we use to describe 
functioning are not meant to be hard-and-fast rules, but only what we 
think would be the most likely information we would encounter in our case 
development.
Comment: One commenter said that the 
wording of § 416.924a(c)(4) of the prior rules (final § 
416.924b(b)(5)) was ambiguous in its use of the phrase 
“development or 
functioning.” This commenter also believed that language in the 
preamble to the publication of the prior rules that explained the 
all-inclusive nature of the domains and behaviors with respect to 
children's functioning should be included in the regulations.
Response: We adopted the comments. 
We deleted from the first sentence of final § 416.924b(b)(5) the 
phrase, “development or”, to emphasize that the domains and 
behaviors do, indeed, address functioning in all children. We added a new 
fourth sentence to explain that the domains and behaviors are intended to 
include all of a child's functioning, and a new fifth sentence to explain 
that all effects of a child's impairment(s) on daily functioning will be 
considered within the domains and behaviors.
Comment: One commenter who was 
concerned that we do not adequately provide for the assessment of children 
with physical impairments, requested that we add to the definition of 
“activities of daily living” a sentence that would indicate 
that activities of daily living may be more useful than developmental 
milestones for evaluating children with physical or nondevelopmental 
impairments.
Response: We believe that our 
revisions to § 416.924b(b)(2) and (3), described in a previous 
response, respond to the comment. With these changes, we now place greater 
emphasis on “activities of daily living” for children who are 
at least 3 years old. In further response to the comment, we have also 
revised the end of the second sentence of § 416.924b(b)(2) to 
indicate that such activities may also be used to evaluate children who 
are younger than age 3.
Section 416.924c 
Other Factors We Will Consider
Comment: One commenter maintained 
that additional language and direction were needed to emphasize the 
relevance of other factors not enumerated in § 416.924d of the prior 
rules (final § 416.924c). The commenter said that, although former 
§ 416.924d(a) of the prior rules (final § 416.924c(a)) states 
that the enumerated factors are “some” of the factors to be 
considered in an individualized functional assessment and 
“are not limited to” the factors enumerated, the section does 
not provide guidance about what those other factors might be. The 
commenter thought it “clear” that there were many other 
factors that could be considered, such as allergies and environmental 
limitations. The commenter referred us to a footnote in the 
Zebley decision. Zebley, 110 
S.Ct. at 894, n.17. Four other commenters echoed this comment in the same 
or similar language, suggesting that we add certain risk factors to the 
section, such as the impact of socioeconomic factors on impairments; 
familial and environmental risks, including parental problems due to age, 
substance abuse, illness, or developmental disability; and effects of 
homelessness, abuse/neglect, and malnutrition.
Response: We did not adopt the 
comment. The first sentence of final § 416.924c states clearly that 
we will consider all factors that are relevant to the evaluation of the 
effects of a child's impairment(s) on his or her functioning. The third 
sentence of the paragraph further states that the factors described in the 
section are some, but not all, of the possible factors that could be 
considered in the evaluation of a child's impairment(s). We included these 
provisions because it would not be possible to identify every factor to be 
considered in the evaluation of every child's claim; each claim presents a 
unique profile of impairment(s) and factors that are particular to that 
child.
In any case, we could not add the “factors” suggested by the 
commenters. Allergies and malnutrition would never be “other” 
factors because they are themselves medically determinable impairments; to 
call them “other” factors would be incorrect and confusing. 
The other suggestions described “risk” factors, which we 
cannot include in this rule or any other, as we explained in the preamble 
to the prior rules and will explain in more detail in our response below 
regarding the use of risk factors.
Finally, the first commenter's reference to footnote 17 in the 
Zebley decision was unclear. The footnote addressed 
“the rigidity of the Secretary's listings-only 
approach” and mentioned the following factors: pain, side effects 
of medication, feeding problems, dependence on medical equipment, 
confinement at home, and frequent hospitalization. 
Zebley, 110 S. Ct at 894, n.17. The Court also 
later in the footnote mentioned “severe swelling, food 
allergies and fever,” in a context which showed that it understood 
that these are medical findings. Aside from the fact that we no longer 
employ a listings-only approach, our rules plainly consider all of the 
factors noted by the Court at steps 2, 3, and 4 of the sequential 
evaluation process. Furthermore, our rules explicitly mention pain (which 
we address in the next three separate comments), side effects of 
medication, dependence on medical equipment, confinement at home, frequent 
hospitalization, and (as in the case of fever) chronic illness.
Comment: Several commenters were 
concerned about what they perceived to be a lack of any reference in our 
new rules to the evaluation of pain and other symptoms in light of the 
Supreme Court's criticism of the way in which we considered pain and other 
symptoms under the listings-only approach we used to deny childhood 
disability claims. These commenters held that the statement in the 
preamble to the prior rules that the childhood regulations, 
“must be read 
in the context of * * * existing rules for determining disability” 
(56 FR at 5537) was inadequate because § 416.929, 
“How we evaluate symptoms, 
including pain,” and 
Social Security Ruling 88-13, 
“Evaluation of Pain and 
Other Symptoms,” did not mention children and were not written with 
children in mind.
Several commenters stressed that symptoms may be particularly difficult to 
evaluate in children because children may not be able to describe their 
own symptoms, may have other problems articulating their symptoms because 
of shame, embarrassment, or fear, may shy away from activities causing 
pain more than adults because they do not understand that pain can be 
overcome or controlled, or, if their symptoms had existed since birth, 
because they had no symptom-free frame of reference. One commenter said 
that these rules “never” mention symptoms.
These commenters stated that adjudicators are more likely to consider a 
child's symptoms if the childhood disability rules specifically require 
them to do so. Therefore, they recommended that we add a paragraph to 
§ 416.924d of the prior rules (final § 416.924c) to include pain 
and other symptoms among the “other factors” we will 
consider. The new paragraph would address the consideration adjudicators 
are to give to allegations of pain and other symptoms in children.
Response: The comments have been 
rendered moot by an event that took place after the close of the comment 
period. On November 14, 1991, we published in the FEDERAL REGISTER final 
rules for the “Evaluation of Symptoms, Including Pain” (56 FR 
57928). These new rules, which revise our previous rules in § 416.929 
for the evaluation of pain and other symptoms, include specific reference 
to the evaluation of symptoms in determining a child's ability to function 
independently, appropriately, and effectively in an age- appropriate 
manner at each step of the childhood sequential evaluation process, and 
were prepared with the evaluation of children in mind.
It is not true that the prior rules “never” mentioned 
symptoms. Section 416.924a(b)(1) of the prior rules (final § 
416.924(g)(1)) requires us to consider evidence of symptoms when we assess 
functioning, as do three of the paragraphs in § 416.924d of the prior 
rules (final § 416.924c), and final § 416.926a(a).
However, we do agree with the commenters who pointed out that children may 
not be able to describe their own symptoms or may have difficulty 
articulating symptoms. Therefore, in response to the comments, we have 
added a new second sentence to § 416.928(a), “Symptoms,” 
which states that we will accept as a statement of a child's symptoms the 
description given by the person most familiar with the child when the 
child is unable to adequately describe his or her symptoms. We have also 
made minor editorial changes to the prior text for context. In response to 
the comments, we have also added to final § 416.924(b) a statement 
that we will evaluate any limitations in a child's ability to function 
that result from symptoms, including pain. We have also added a statement 
to final § 416.924b(b)(5) that the presence of pain or other symptoms 
can adversely affect functioning in the domains or behaviors. We continue 
to emphasize, however, that these childhood disability rules must be read 
in the context of all the other rules governing the evaluation of 
disability. Thus, every reference to an “impairment” and to 
“medical 
findings” carries with it the requirement to obtain evidence about 
and consider “symptoms, signs, and laboratory findings,” as 
set forth in §§ 416.908, 416.928, and 416.929.
Comment: One commenter said that the 
Eighth Circuit in Polaski v. Heckler, 739 F.2d 1320 
(8th Cir. 1984) specifically held that we must consider allegations of 
pain and other subjective complaints. The commenter noted that Polaski 
required us to give full consideration to all evidence, including (1) the 
claimant's daily activities; (2) the duration, frequency, and intensity of 
pain and other subjective complaints; (3) precipitating and aggravating 
factors; (4) dosage, effectiveness, and side effects of medication; and 
(5) functional restrictions. Another commenter thought that the absence of 
a reference to pain in the childhood disability rules will be in violation 
of the law set forth in Marcus v. Califano, 615 F.2d 23, 27 (2d Cir. 
1979). The commenter said that the Marcus decision held that, as long as 
an actual impairment had been established by medically acceptable clinical 
and/or laboratory techniques, the absence of objective medical evidence 
could not be grounds to reject or find not credible a claimant's 
statements as to the pain associated with that impairment.
Response: Revised § 416.929, 
“How we evaluate symptoms, including pain,” contains language 
that addresses the holdings in both of these cases, as well as others. 
Section 416.929(c)(3) of the regulations states that factors relevant to a 
claimant's symptoms include the five factors from Polaski cited in the 
comment, and several others. (See 56 FR at 57946.) The second commenter 
did not point to any language in the prior childhood rules which led to 
the belief that we would require children to establish the existence and 
severity of their symptoms through objective medical evidence. We do not 
know of any language in these rules that could have led the commenter to 
such a belief. In any case, revised § 416.929(b) of our rules 
provides that a person must have a medically determinable impairment which 
could reasonably be expected to produce the pain or other symptoms. The 
rule specifically states: “The finding that your impairment(s) could 
reasonably be expected to produce your pain or other symptoms does not 
involve a determination as to the intensity, persistence, or functionally 
limiting effects of your symptoms.” The fourth sentence of revised 
§ 416.929(c)(2) further states: 
“* * * we will not reject your statements 
about the intensity and persistence of your pain or other symptoms or 
about the effect your symptoms have on your ability to work (or if you are 
a child, to function independently, appropriately, and effectively in an 
age-appropriate manner) solely because the available objective medical 
evidence does not substantiate your statements.” (Both cites at 56 
FR at 57945.)
Thus, we believe that these final childhood disability rules, which must 
be read in the context of our existing policies for the evaluation of pain 
and other symptoms, are not inconsistent with the circuit court rulings in 
either of the cited cases. Our rules make clear that, once an adjudicator 
determines that the individual has an impairment which is reasonably 
expected to produce the alleged symptoms, the adjudicator must consider 
all of the evidence relevant to the individual's alleged symptoms, even if 
the alleged symptoms are more severe or persistent than would be expected 
from the objective medical findings.
Comment: Two commenters suggested 
that we convene an “advisory panel” similar to the Pain 
Commission, or consult with multidisciplinary experts, to consider pain in 
children and how best to evaluate it and other symptoms in the disability 
determination process. They argued the need for such an effort because 
children may experience and respond to pain differently than do 
adults.
Response: The recommendation goes 
beyond the scope of these rules. Nevertheless, we believe that the rules 
we published on November 14, 1991, are sufficient to guide adjudicators in 
the evaluation of pain and other symptoms in children. Section 416.929 of 
our rules contains a detailed discussion of our policies on the evaluation 
of pain and other symptoms. These policies include specific reference to 
the evaluation of symptoms in determining a child's ability to function 
independently, appropriately, and effectively in an age-appropriate manner 
and were prepared with the evaluation of children in mind. However, we 
agree with the commenters that children may experience and respond to 
their symptoms differently than do adults. Therefore, we have revised 
§ 416.928(a) to expand the definition of our term 
“symptoms” to recognize the problems children may have 
articulating their symptoms. Further, our current policies and procedures 
provide for the use of pediatric experts, where indicated, for 
consultative examinations, including experts in pediatric pain, where 
appropriate and available. Finally, under the provisions of 
§ 1614(a)(3)(H) of the Act, 
we will make reasonable efforts to ensure that a qualified pediatrician or 
other appropriate specialist evaluates each childhood case; such 
individuals are aware of the special problems of evaluating symptoms in 
children.
Comment: Several commenters urged us 
to include in § 416.924d of our prior rules (final § 416.924c) 
an explicit consideration of the impact of “risk factors” on 
a child's functioning. The commenters said that by 
“risk factors” they mean biological factors (e.g., low birth 
weight, neonatal seizures, anemia, recurrent infections, spinal, cardiac, 
and pulmonary abnormalities), health-related factors (e.g., inadequate 
treatment, lack of access to treatment facilities and therapy centers), 
and familial/environmental factors (e.g., malnutrition, homelessness, poor 
air quality, parental substance abuse, dysfunctional family environment, 
history of physical or sexual abuse). One commenter added that the 
conditions that manifest themselves due to risk factors can be physical or 
mental/emotional in nature.
The commenters said that the Supreme Court emphasized in 
Zebley that we must take into account all relevant 
factors in child claims (e.g., age, educational background, and 
circumstances), and the commenters regarded risk factors among the 
circumstances to be considered. One commenter, who was not a pediatrician, 
said that “standard pediatric practice” takes risk factors 
into account in evaluating the severity of pediatric impairments, and that 
risk factors are indispensable in making longitudinal judgments about 
pediatric impairments. For example, the commenter thought that if a child 
has been abused it is relevant to consider that experience in order to 
arrive at a valid prognosis and to make informed decisions about 
duration.
The commenters noted several points we made in the preamble to the prior 
rules (56 FR at 5551). Most importantly, the commenters noted our position 
that a rule incorporating certain risk factors for children results only 
in a prediction of the possibility of future disability, and that to count 
certain factors again, after they have already been considered in the 
course of an equivalence determination or an individualized functional 
assessment, would be a double weighing of the same factors. The commenters 
asserted that elimination of express references in the regulations to 
“risk factors” is not necessary; rather we should provide 
language that avoids these problems. For example, one commenter said that 
many children with biological conditions that are not overt (e.g., spina 
bifida occulta, congenital heart problems) are already functionally 
impaired, at the very least by prophylactic orders from treating 
physicians; the commenter argued that consideration of risk factors may 
contribute to findings of current disability in these cases.
Some commenters also suggested that allowances based on predictions of 
disability can be appropriate. For example, one commenter said that, 
“without an express provision allowing the consideration of such risk 
factors * * * many claims in which the current level of functional 
impairment is not sufficient will be denied by lay adjudicators who may 
discount subtle but very serious underlying problems where consequences 
have yet to manifest themselves.” (Emphasis in original.) One 
commenter maintained that the assumption made in the preamble to the 
regulations that risk factors may have an 
“observable, current impact” and, therefore, will be 
considered in the individualized functional assessment, is not supported 
by the language of the regulations. The commenter said that risk factors, 
“must be expressly laid out for lay adjudicators” and 
administrative law judges. To overcome our concerns about the 
intrusiveness of inquiry into risk factors, as explained in the preamble 
to the prior rules, the commenter recommended that we limit consideration 
of risk factors, 
“to those that are objectively observed as affecting the 
particular child.”
In addition to the commenters who proposed that we add a new paragraph to 
§ 416.924d of our prior rules (final § 416.924c) specifically 
directing the consideration of risk factors, another commenter proposed 
that we add a new domain titled, 
“Abilities as affected by environment,” to § 
416.924c(a)(2) of our prior rules (final § 416.924d(c)) to address 
the ways in which a child's environment may contribute to, or decrease, 
the chance that a disability will improve.
Response: We did not adopt the 
comments. As we discussed in the preamble to the prior rules (56 FR at 
5551), we do consider what the commenters called 
“risk factors” insofar as they affect the child's medical 
status and ability to function in an age-appropriate manner. As we 
explained in the preamble to the prior rules, many of the factors 
mentioned are covered in various ways in the rules. For instance, the 
so-called biological risk factors mentioned by the commenters (neonatal 
seizures, anemia, low birth weight, recurrent infections, and spinal, 
cardiac, and pulmonary abnormalities) as well as two of the 
familial/environmental factors (malnutrition and history of physical or 
sexual abuse) are, in these rules, “medically determinable 
impairments,” or the effects of medically determinable impairments, 
or (as in the case of abuse) the cause of medically determinable 
impairments. To call these “other factors” or 
“risk factors” would only be confusing since we have always 
considered these “factors” in our determinations. Indeed, 
these “factors” can be disabling or be the cause of 
impairments that are.
The other categories of “risk factors” named by the 
commenters do not contribute to our determinations of disability except if 
one holds—as some of the commenters did and we cannot—that a 
child who is not currently disabled may be granted benefits based on a 
prediction of future disability. If a child has a disabling respiratory 
impairment, we will find the child disabled: We do not have to consider 
that the child lives in an environment with poor air quality or receives 
substandard medical treatment to make this determination, just as we would 
not use such factors to find the child not disabled.
As we explained in the preamble to the prior rules, these kinds of factors 
are not relevant to a determination of disability. A child is either 
disabled or not, and we cannot say that the fact of homelessness or the 
fact that the child's parents abuse drugs can be additional factors that 
make the difference between a finding of “disabled” and a 
finding of “not 
disabled” without contravening the law. We do not agree with the 
assertion by one of the commenters that 
“standard pediatric practice” takes risk factors into account 
in evaluating severity, although we would agree that these factors are 
relevant to such issues as etiology, treatment plan, and prognosis.
Returning to the issue of “biological risk factors,” we want 
to assure the commenters about spina bifida occulta and other hidden 
conditions that these rules already provide for the kind of considerations 
the commenters feared we would overlook. If a child with spina bifida is 
unable to engage in strenuous play because there is a real danger of 
paralysis, we would find that child to be medically limited in the ability 
to engage in strenuous play, even if the child is otherwise asymptomatic 
and able to do less strenuous activities. (This does not mean that we 
would find the child disabled; whether the child would be found disabled 
would depend on the extent to which the child is limited by his or her 
impairment.) Final § 416.924c(d) and (e) also address this subject: 
The example is of a child who has structured his or her life (i.e., by 
avoiding strenuous play) so as to minimize the chance of devastating 
injury. Also, as a general matter, final § 416.924d(a) says, 
“When we assess your 
functioning, we will consider all information in your case record that can 
help us determine the impact of your impairment(s) on your physical and 
mental functioning”; similar directives are found throughout the 
rules. We require our adjudicators to develop and consider all 
impairment-related effects on function.
Thus, for purposes of assessing current disability, we believe the rules 
fully cover “risk factors” to the extent possible under the 
statute. Insofar as some commenters suggested that consideration of risk 
factors will allow us to predict future disability, we must repeat that 
allowances based on such predictions alone are contrary to the Act.
Comment: Three commenters focused on 
the importance of an impaired child's need for early professional care. 
The commenters said that many children have primary conditions which, if 
not treated with the necessary medical and allied professional 
interventions, will worsen and produce secondary deficits. Moreover, the 
child might be tracked into an educational program more restrictive than 
would have been necessary had the child been given early and proper 
treatment. The commenters thought that, by recognizing and considering 
risk factors, we could make early intervention possible through the 
assistance of SSI and the Medicaid entitlement that accompanies SSI in 
most states.
Response: We do know of the 
importance of early intervention for children with impairments. However, 
we are not legally able to provide SSI eligibility for children who are 
not disabled within the time period covered by their application for 
benefits. There are programs designed to provide early intervention for 
children at risk (e.g., Part H of the Individuals with Disabilities 
Education Act (IDEA) and Headstart), but the Social Security Act's 
disability provisions do not allow us to pay benefits to children who are 
not disabled, but who may become disabled in the future.
Comment: One commenter recommended 
language for the first and second sentences of § 416.924d(b) of the 
prior rules (final § 416.924c(b)) to convey the idea that a child 
might have a chronic impairment(s) which causes periods of debility but 
which does not necessarily always require hospitalization or outpatient 
care. Other commenters were concerned that § 416.924d of the prior 
rules did not address the possibility of children with episodic 
impairments.
Response: We adopted the comment, 
but did not use the language the first commenter recommended. Instead, we 
added a new first sentence to the provision, which states: 
“If you have a 
chronic impairment(s) that is characterized by episodes of exacerbation 
(worsening) or remission (improvement), we will consider the frequency and 
severity of your episodes of exacerbation and your periods of remission as 
factors in our determination of your overall ability to function.” 
We revised the next sentence (the prior first sentence of the paragraph) 
to state: “For instance, if you require repeated hospitalizations or 
frequent outpatient care with supportive therapy for a chronic 
impairment(s), we will consider this need for treatment in our 
determination.” We then replaced the last sentence with two 
sentences that more clearly explain how we consider the need for treatment 
and the frequency of exacerbations in the disability determination. The 
revisions better convey our original intent for this provision, which was 
to give some guidance for the evaluation of children who have chronic, 
episodic impairments that may not always limit their functioning (or may 
limit their functioning to a lesser extent during periods of remission) 
but who, on a longitudinal basis, may be so frequently and severely 
limited as to be disabled.
Comment: Comments and questions we 
received from three commenters pointed out that the language in § 
416.924d(e) of the prior rules, “Adaptations,” was unclear. 
One commenter wanted to know whether, following the language of the rule, 
we could conclude that a child with cerebral palsy who is nonverbal and 
unable to walk is not disabled if the child can communicate with an 
electronic device or a manual system and can get around in a motorized 
wheelchair. The commenter thought that the evaluation of these adaptations 
should be similar to the evaluation of the factors discussed in § 
416.924d(d) of the prior rules, 
“Effects of structured or highly supportive settings.” That 
is, the commenter thought we should consider the child's ability to 
function without an adaptation in a way comparable to the way we consider 
a child who functions better in a highly structured setting but is still 
impaired in age-appropriate settings. In a similar vein, a second 
commenter noted that even with the best device, a person who is otherwise 
nonverbal can only communicate somewhat better than not at all, but still 
not normally. This commenter suggested that communication devices could 
fall under the category of adaptations that may “impose additional 
limitations,” or, alternatively, be listed as a self-care 
activity.
The third commenter thought our statement that some adaptations “may 
impose additional limitations that interfere with performance of 
age-appropriate activities” was problematic. The commenter pointed 
out that the examples we provided were of devices that 
“enable” a person to do an activity; they did not actually 
illustrate adaptations that would in themselves cause limitations. For 
example, the commenter noted that a child who required an adapted utensil 
would not be able to eat in the school cafeteria without the utensil, but 
would be able to do so with the utensil. The utensil itself does not 
impose additional limitations; rather, it enables the child to do 
something. Indeed, the commenter said that, if an adaptive device imposes 
a limitation that was not previously present (i.e., that was not part of 
the impairment itself) it would be necessary to reevaluate the 
appropriateness of the device.
Finally, one of the commenters said that the child who needs an adaptation 
in order to function may depend upon Medicaid (through SSI) to obtain the 
adaptation. The commenter recommended that we clarify § 416.924d(e) 
to explain both the benefits to a child's functioning attributable to an 
adaptation and the potential loss of functioning attributable to the loss 
of an adaptation. The purpose of such clarification would be to ensure 
that children do not end up in recurring cycles of SSI eligibility and 
non-eligibility based on the absence or presence of such 
adaptations.
Response: We adopted the comments by 
revising § 416.924d(e) of the prior rules (final § 416.924c(e)) 
to make it clearer. Our intent in this rule was to evaluate the impact of 
adaptations essentially as the commenters thought we should. Children 
whose functioning is improved with an adaptation may function normally, or 
almost normally, but many children only function better, not necessarily 
independently, appropriately, and effectively in an age-appropriate 
manner. For instance, an ankle-foot orthosis may enable a child to walk 
independently, but the child may still be unable to run and engage in 
certain play activities; although the child's ability to function is 
increased, his or her abilities are still limited to some extent. 
Certainly, we consider a child who is unable to communicate without the 
assistance of an electronic device to be limited in the communicative 
domain, even though the device may enable the child to communicate to some 
extent.
We also agree with the third commenter that the examples of adaptations 
that may impose additional limitations did not illustrate the principle. 
They are not in themselves intrusive—as in the example of the 
special utensil, they enable children to function better, even if not 
“normally.”
For these reasons, we revised the paragraph to state that some adaptations 
(such as eyeglasses and hearing aids) may enable a child to function 
normally, or almost normally, whereas others (such as ankle-foot orthoses, 
hand or foot splints, and other adaptations we formerly said could be 
intrusive) may increase functioning even though the child is still 
functionally limited.
(We deleted the reference to “sleeping” because it was 
unclear.) In the second case, the extent of the limitation will, of 
course, vary from case to case. These revisions are not a change in our 
original intent, but the comments did enable us to better express our 
intent.
In clarification of the first commenter's concerns, we also note that 
children who must use wheelchairs or who cannot produce speech by any 
means have impairments that meet or equal the listings. Therefore, we 
would not be concerned with evaluating the effects of these kinds of 
adaptations, which do not so much improve the particular function as 
substitute for it.
With regard to the suggestion that we employ a method similar to the rules 
for highly structured settings, we believe that the revisions accomplish 
the end the commenter had in mind, which was to recognize that children 
who use adaptations may still not be functioning independently, 
appropriately, and effectively in an age-appropriate manner. We do not 
believe that there is a valid comparison between a child's ability to 
function with or without an adaptation and a child's ability to function 
within or outside of a highly structured or supportive setting. A highly 
structured setting (such as a special class for children with behavioral 
problems) is an abnormal environment. In this situation, we need to 
determine how the child will function outside the setting—i.e., how 
the child will function in the settings that are normal to children of the 
child's age—because structured settings may mask how severely 
impaired—or typical—a child really is compared to other 
children.
Adaptations, on the other hand, may enable a child to function 
independently, appropriately, and effectively in an age-appropriate 
manner—i.e., they may enable the child to do normal activities in 
normal settings—or, at least, improve that ability. Knowing how the 
child would function without the adaptation does not really tell us 
anything about how the child can function. To take an obvious example, 
many children would have very serious visual impairments if they were not 
to wear glasses, but can see normally with glasses. However, a child who 
must use a built-up spoon or a rocker knife has augmented his or her 
functioning but is obviously still limited in the motor domain.
Comment: One commenter urged us, 
when applying the policy in § 416.924d(f) of the prior rules, final 
§ 416.924c(f), concerning multidisciplinary therapy, to take into 
consideration the time commitment necessary for children with cystic 
fibrosis to perform chest therapy three or four times a day. Although 
these children may continue to attend school, performing the needed 
therapy several times a day can be very time-consuming and may seriously 
impede their ability to keep up with peers. Consideration of this factor 
may strongly influence a disability determination about these children. 
Another commenter asked us to remove all references to multidisciplinary 
therapy and focus only on the time spent in treatment.
Response: We adopted the comments. 
In the fifth sentence of final § 416.924c(f), we deleted the words, 
“in order to go,” from the opening clause of the prior 
language, “If you 
must frequently interrupt your activities at school or at home in order to 
go for therapy * * *,” to convey the idea that the therapy may be 
given at home or school.
We adopted the second comment by changing the heading of final § 
416.924c(f) from “Multidisciplinary therapy” to 
“Time spent in therapy”. In addition, in the first sentence, 
we changed the phrase, “more than one 
kind of health care professional”, to 
“one or more kinds of health care 
professionals” to indicate that even one kind of therapy can be 
very time-consuming. The second sentence now refers simply to 
“therapy,” which may include multidisciplinary therapy. 
Nevertheless, this paragraph still provides for the situation in which 
each kind of therapy a child receives may not in itself involve much time 
but, cumulatively, the time spent in the various modes of therapy is 
significant.
Comment: One commenter was concerned 
about the statement in the second sentence of § 416.924d(g) of the 
prior rules (final § 416.924c(g)) that if a child attends school, 
“we will consider this evidence.” The commenter was concerned 
about the situation in which we try, but are unable, to obtain evidence 
from the school.
Response: We adopted the comment. We 
revised the sentence to state that if a child attends school, we will 
consider this evidence when it is relevant and available to us. This 
revision more accurately reflects our policy and current development 
procedures and is consistent with the first sentence of the section, which 
explains that school records and information from people at school who 
know the child “may” be important sources of information. In 
some cases, such as allowances in which the child has an impairment that 
meets or medically equals a listing, or in which it is clear from the 
evidence that there is no limitation in the child's functioning at school, 
we may be able to make a decision without obtaining information from the 
school. The revision, therefore, covers the situations in which we try to 
get evidence from school but fail, and in which evidence from school is 
not necessary to reach a decision.
Comment: One commenter said that, 
since the law mandates that developmentally disabled children be 
mainstreamed in regular classrooms, it is important to note in the 
childhood disability regulations that attendance in a regular classroom is 
not totally indicative of nondisability. We must also consider whether the 
child can function independently in that classroom in an age-appropriate 
manner.
Response: We have adopted the 
commenter's suggestion to add the word “regular” before the 
word “classroom” in the second sentence of final § 
416.924c(g)(2). We also added the words 
“appropriately, and effectively” to the phrase “to 
function independently,” in order to include all the 
characteristics of a child's functioning in a regular classroom that we 
would consider in our evaluation. We made a similar addition to final 
§ 416.924c(g)(3), adding after “to function” the phrase, 
“independently, appropriately, and 
effectively.”
Section 416.924d 
Individualized Functional Assessment for Children
Comment: One commenter noted that 
§ 416.926a(c), lists the individuals who have responsibility for 
making determinations of equivalence at each stage of the administrative 
review process. The commenter noted that we had omitted a corresponding 
section in § 416.924e stating the responsibility for the 
individualized functional assessment.
Response: We adopted the comment. We 
have added a new paragraph (b) to final § 416.924d to list the 
individuals who have the overall responsibility for the individualized 
functional assessment. The new paragraph does not contain any changes in 
policy, but only incorporates our policy as we have been applying it since 
we first published the prior rules. It is also consistent with the rules 
stating responsibility for equivalence in childhood claims and residual 
functional capacity assessments in adult claims. We adopted the first and 
third sentences of the paragraph from § 416.926a(c), with appropriate 
modifications to make it relevant to the individualized functional 
assessment. (In the first sentence, after “designee,” we 
added the phrase, “of the Secretary.” Since this phrase was 
missing from the first sentence of § 416.926a(c), we also added it to 
that sentence in the same place.) We adopted the second sentence from the 
third sentence of § 416.946, the provision in the adult rules setting 
out the responsibility for residual functional capacity assessments, again 
with minor revisions, to make the statement relevant to the evaluation of 
children. Finally, we redesignated the following paragraphs because of the 
insertion of the new paragraph.
Comment: One commenter, whose 
particular concern is the emotional development of young children, made 
recommendations for improving the descriptions of the social development 
of newborns and young infants in § 416.924c(b) of the prior rules 
(final § 416.924d(e)), and the cognitive and social development of 
older infants and toddlers in § 416.924c(c) of the prior rules (final 
§ 416.924d(f)).
Response: We adopted the language 
recommended by the commenter with minor amendment. However, in two 
instances, we used the language the commenter provided but placed it under 
different domains than were recommended. We also revised the sections of 
the rules for older children in a similar manner to maintain consistency 
among the rules and because we believe that the commenter's suggestions 
have applicability to older children as well. These changes are not 
substantive; they merely provide greater detail and accuracy to the 
descriptions we originally published.
In response to the comment, we revised the example of social development 
for newborns and young infants in § 416.924c(b)(4) of the prior rules 
(final § 416.924d(e)(4)) to state, “* * * your ability to form 
patterns of self- regulation, to form and maintain intimate relationships 
with your primary caregivers, and to exchange a variety of age- 
appropriate emotional cues and begin to organize intentional behavior * * 
*.” In § 416.924c(c)(1) of the prior rules (final § 
416.924d(f)(1)), we added the following language to the examples of 
cognitive development in older infants and toddlers: “* * * and by 
knowing what you want as illustrated, for example, by searching for a toy 
or asking for a special food * * *.” We also made minor editorial 
revisions to the sentence to accommodate the new language.
We expanded the examples in § 416.924c(c)(2) of the prior rules 
(final § 416.924d(f)(2)), describing communicative development in 
older infants and toddlers by including most of the commenter's more 
precise language. The new language is, 
“* * * your ability to communicate 
your wishes or needs by using gestures or pretend play, and by 
understanding, imitating, and using * * *.” The commenter had 
recommended that some of this language be used to describe the domain of 
social development, but we believe that it more accurately describes 
communicative development as used in these rules.
In § 416.924c(c)(4) of the prior rules (final § 416.924d(f)(4)), 
we deleted the phrase, “and emotional bonding with,” from the 
example of social development and revised the example to state, 
“* * * 
your ability to express normal dependence upon, and intimacy with, your 
primary caregivers, as well as increasing independence from them, to 
initiate and respond to a variety of age-appropriate emotional cues, and 
to regulate and organize emotions and behaviors * * *.” We deleted 
“emotional bonding” because we agree with the commenter that 
this descriptor is generally applicable only to the youngest infants 
(i.e., those in the birth to age 1 category); the replacement language is 
more accurate and detailed.
In § 416.924c(c)(5) of the prior rules (final § 416.924d(f)(5)), 
personal/behavioral development, we added the phrase, “in 
responding to limits,” after the phrase, “in adapting to your 
environment.” This, too, was language the commenter suggested for 
the domain of social development; however, it comports more closely with 
our definition of personal/behavioral functioning, which concerns a 
child's learning and demonstrating self-control. In addition, in § 
416.924c(d)(5) of the prior rules (final § 416.924d(g)(5)), we 
extended this same descriptor to preschool children, for whom learning 
self-control is also as important as it is for older infants and toddlers. 
In a related change, we deleted the phrase “self-control” 
from § 416.924c(d)(4) of the prior rules (final § 
416.924d(g)(4)), social development of preschool children.
Although the foregoing comments were confined to children from birth to 
age 3, we believe that the suggestions made by the commenter about social 
functioning have applicability for other age groups and that, to maintain 
consistency among the rules, we made similar changes to the rules for 
older children. Therefore, to emphasize the continuity of social 
development across age groups, we have added parallel descriptors for 
preschool and school-age children and young and older adolescents in 
§§ 416.924d(g)(4) (for preschool children), 416.924d(h)(4) (for 
school-age children), 416.924d(i)(4) (for young adolescents), and 
416.924d(j)(2) (for older adolescents). The descriptors refer to a child's 
ability to initiate age- appropriate social exchanges and friendships and 
to respond appropriately to social environments (i.e., to individuals and 
to groups) with increasingly complex interpersonal behaviors.
Comment: One commenter seemed 
pleased that we included responsiveness to stimuli for the youngest group 
of children, newborns and young infants in § 416.924c(b)(5) of the 
prior rules. However, the commenter recommended the addition of the 
phrase, “ * * * and all sensory stimulation,” or the addition 
of specific descriptions of the other kinds of sensory input that infants 
experience, i.e., vestibular or proprioceptive stimulation.
Response: In response to the 
comment, we clarified the descriptor. As written, § 416.924c(b)(5) of 
the prior rules (final § 416.924d(e)(5)) stated that a child's 
ability to respond appropriately to visual, auditory, and tactile 
stimulation was only an example of a child's responsiveness to sensory 
stimuli, rather than the definition of such responsiveness. Therefore, to 
make our intention clearer, we rephrased the provision to say: 
“Responsiveness to stimuli, i.e., your ability to respond appropriately to 
stimulation, e.g., visual, auditory, and tactile.” Because the 
sensory responses in the descriptor are only examples, other kinds of 
sensory input (such as vestibular, proprioceptive) are included. Also, if 
we were to add a phrase including “all” sensory stimuli, the 
senses we mentioned would no longer be examples.
Comment: One commenter found 
commendable the inclusion of the factor of 
“adapting to the environment” in the personal/behavioral 
domains for older infants and toddlers in § 416.924c(c)(5) of the 
prior rules and for preschool children in § 416.924c(d)(5) of the 
prior rules. The commenter observed, however, that adaptation to the 
demands of the environment and the settings in which people function is a 
continuous process throughout life and a primary contributor to 
functioning at all ages. Therefore, the commenter recommended that we add 
similar language to the sections applicable to school-age children, young 
adolescents, and older adolescents.
Response: We accepted the comment 
and added the appropriate language to final §§ 416.924d(h)(5) 
(for school-age children) and 416.924d(i)(5) (for young adolescents). We 
also added a cross-reference at the end of § 416.924d(j)(1), for 
older adolescents, which incorporates by reference the descriptions of 
domains and behaviors in § 416.924d(i), the section for younger 
adolescents, and therefore accomplishes the same end.
Comment: Another commenter provided 
many comments concerning the area of communicative development and 
functioning in children. The commenter recommended that we maintain 
continuity with our description of the communicative ability of children 
ages 1 to 3 years in § 416.924c(c)(2) of the prior rules—i.e, 
to eventually form two-to-four word sentences—by providing a 
description of the ability of children from age 3 to 6 years to form 
complete sentences in grammatical form. The commenter also noted that our 
descriptor for children age 6 to 12 years in § 416.924c(e)(2) of the 
prior rules described the ability to communicate pragmatically 
“or” conversationally. The commenter pointed out that by age 
6 to 12 years a child should be able to communicate both pragmatically and 
conversationally; therefore, the commenter recommended that we use the 
conjunctive “and” rather than the disjunctive 
“or.” Similarly, the commenter also recommended that the 
description of communication for young adolescents in § 
416.924c(f)(2) of the prior rules should include the ability to express 
complex thoughts, with increased vocabulary, in a spontaneous and 
interactive manner.
The commenter also noted that in § 416.924c(d)(4) of the prior rules 
for children age 3 to 6 years, we included the ability to relate to a 
group, but we did not mention group relationships (except obliquely) in 
the communicative and social domains for subsequent age groups. The 
commenter also thought our descriptors varied from age group to age group. 
The commenter remarked that by the ages of 6 to 12, a child should be able 
to initiate communication in all communication environments and with all 
communication partners. Finally, the same commenter observed that the 
examples given to guide determination of an older adolescent's ability to 
do work-related activities did not include any statements about 
communication proficiency. The commenter recommended that we include 
communication proficiency in the factors to be considered regarding older 
adolescents.
Response: We adopted the comments. 
In final § 416.924d(g)(2) (§ 416.924c(d)(2) of the prior rules), 
we added the words, 
“using simple sentences in grammatical form,” to the end of 
the descriptor of the communicative domain for preschool children. In 
final § 416.924d(h)(2) we changed the conjunction “or” 
to “and” in the three places in which it appeared, and added 
language for consistency with other rules, as already described. The 
descriptor now reads, “* * * 
your ability to communicate pragmatically * * * and conversationally 
(i.e., to exchange information and ideas with your school classes, with 
peers, and family) in a spontaneous, interactive, sustained and 
intelligible manner * * *.” In final § 416.924d(e)(2), (f)(2), 
(g)(2), (h)(2), (i)(2), and (j)(2), we added the words “spontaneous, 
interactive” or similar language to the descriptor of 
communication; even though the comment was directed only at final § 
416.924d(i)(2), for young adolescents, we believe that it is relevant to 
all of the age categories.
To address the commenter's concerns about the ability of older children, 
as well as preschool children, to relate to, and communicate with, groups 
as well as individuals, we made the following changes: For school-age 
children, as suggested, we changed the phrase, 
“in your classroom,” to 
“with your school classes” in the parenthetical statement in 
final § 416.924d(h)(2); and, in final § 416.924d(h)(4), we 
deleted, “to your 
siblings and parents or caregivers,” and added the more precise 
language after the word “relate,” 
“appropriately to individuals and groups (e.g., 
siblings, parents or caregivers, peers, teachers, school classes, 
neighborhood groups) * * *.”
For young adolescents, in final § 416.924d(i)(2), beginning with the 
word “conversationally,” we have replaced the remainder of 
the clause with, 
“* * * to converse spontaneously and interactively, expressing 
complex thoughts with increasing vocabulary in all communication 
environments (e.g., home, classroom, playground, extra-curricular 
activities, job) and with all communication partners (e.g., parents or 
caregivers, siblings, peers, school classes, teachers, other authority 
figures) * * *.” We also revised the paragraph on social function, 
final § 416.924d(i)(4), to be consistent with other corresponding 
sections. Finally, in final § 416.924d(j)(2), we have added a new 
third sentence to address communication in older adolescents.
Comment: The same commenter also 
offered an additional comment concerning children who are nonverbal, 
particularly children with the physical impairment cerebral palsy. The 
comment was directed specifically at the descriptor for communicative 
development for preschool children in § 416.924c(d)(2) of the prior 
rules (final § 416.924d(g)(2)), which refers to a child's 
“* * * 
telling, requesting, predicting, and relating information * * *.” 
The commenter noted that children with cerebral palsy who are nonverbal 
may be able to make some guttural noises and gesticulations that 
approximate interactive communication, but that are so limited that they 
do not constitute effective, meaningful communication. The commenter was 
concerned that the language of our rules might be misinterpreted to 
include such output as effective functioning. The commenter, therefore, 
recommended that we add a reference to the development of interactive 
communicative skills, which would ensure that the more limited expression 
of nonverbal children not be construed as “normal.”
Response: We adopted the comment in 
final § 416.924d(g)(2) by adding the word “interactive” 
to the descriptor. As with all functions described by these rules, it was 
always our intent that, fundamentally, any evaluation of a child's ability 
to communicate would have to consider its practical success as compared 
with age-appropriate norms, but we agree that the simple addition of the 
word “interactive” will make our intent clearer. Because we 
believe that the comment is relevant to other age groups as well, and for 
the sake of consistency among the rules, we have also made the same 
addition to the sections on communication for the other relevant age 
categories.
We would like to point out, however, that the commenter described a 
communication impairment that would meet the criteria of a listing; in 
fact, a child with cerebral palsy need not have as severe a communication 
impairment as described by the commenter to meet the requirements of our 
listings. Listing 111.07 may be satisfied by a child with cerebral palsy 
if the child also has a 
“significant interference with communication due 
to speech, hearing or visual defect”; the child need not be 
nonverbal. Moreover, children with other physical impairments that cause 
the level of speech impairment described by the commenter may meet Listing 
2.09 if they are unable to produce by any means speech which can be heard, 
understood, and sustained. Nevertheless, there will be children who have 
impaired communication abilities that are not of listing-level severity, 
and we want to ensure that the descriptors for evaluating communication 
are complete.
Comment: One commenter was aware 
that we had created charts for our manual instructions to display the 
functional descriptors in § 416.924c in prior rules. The commenter 
noted that the charts include “conceptual growth” under the 
cognitive domain for young adolescents, a descriptor that was not in the 
regulations section. The commenter suggested that we add it.
Response: As suggested, we added the 
term, “conceptual growth,” to final § 416.924d(i)(1), 
the cognitive domain for young adolescents.
Comment: Several comments were made 
concerning the discussion of functioning of older adolescents in § 
416.924c(g) of the prior rules (final § 416.924d(j)). Two commenters 
noted that functional domains and behaviors and their descriptors were not 
included for this age group. Another comment recommended that we delete 
the reference to remembering “short instructions” in the 
discussion of the school activities that would be considered as evidence 
of an older adolescent's ability to function in a job setting because 
“there is more 
to employability than just taking 'short' instruction.” Finally, 
one commenter thought that there was an implicit presumption in § 
416.924c of the prior rules that older adolescents without impairments 
function like adults. The commenter observed that in some domains, older 
adolescents may function in a manner similar to that of adults, but in 
areas involving cognitive skills and judgment, their functioning is less 
similar to that of adults.
Response: We adopted the comments 
about adding a reference to the functional domains and behavior for older 
adolescents by adding at the end of final § 416.924d(j)(1) (§ 
416.924c(g)(1) of the prior rules) a cross-reference to the descriptors in 
final § 416.924d(i)(1)-(5), which are also applicable to older 
adolescents. For consistency throughout the rules, we also added 
statements to the first sentences of final § 416.924e(d)(2) and (3) 
referring to the domains. We also changed “short instruction” 
to “simple 
instruction,” which is not only more accurate, but consistent with 
the description of basic work-related activities in other regulations 
sections (e.g., § 416.921).
Finally, we do maintain, as stated in final § 416.924e(d)(1), that 
children aged 16 to 18 who do not have impairment-related limitations are 
ordinarily expected to be able to do the kinds of physical and mental 
activities that are expected of persons who are at least 18 years old. We 
believe that this is a reasonable policy because it is consistent with 
current knowledge about the abilities of 16- and 17-year-olds as compared 
with 18- and 19-year-olds. For the same reason, we have articulated the 
principle in final § 416.924a(d)(4) that older adolescents generally 
share with the youngest adults (i.e., 18-years-olds) the same abilities to 
adapt to work-related activities despite a severe impairment(s).
Comment: Six commenters submitted 
comments that discussed in identical or similar language the efficacy of 
these rules as they apply to the evaluation of children with physical 
impairments. Several of these commenters said that, although the domains 
of functional assessment in §§ 416.924c and 416.924d of the 
prior rules (final §§ 416.924d and 416.924e) are reasonable for 
determining developmental disability, they are insufficient for 
determining physical disability. They also said that the regulations, in 
general, fail to provide appropriate guidance for the evaluation of 
physical impairments. One commenter said that 30 percent of children 
suffer from physical impairments, many of which do not have much effect on 
development.
One commenter thought that the problem was that we had borrowed 
developmental terms from the pediatric community that have received 
meanings which are used only in certain contexts. The commenter said that, 
because we were implicitly altering the meanings of these terms and using 
the concept of “domains” as an all-inclusive framework, we 
were increasing the potential for confusion and making our adjudications 
more difficult.
Response: We disagree with the 
commenters' view that the domains of functional assessment are not 
adequate for the purpose of evaluating physical disability in 
children.
We first repeat the definition of “domains” in final § 
416.924b(b)(5), “Domains and Behaviors,” in these final 
rules:
The terms “developmental domains,” 
“functional domains,” and “behaviors,” which we 
use when we perform an individualized functional assessment, refer to 
broad areas of development or functioning that can be identified in 
infancy and traced throughout a child's growth and maturation into 
adulthood. The domains describe the child's major spheres of 
activity—i.e., physical, cognitive, communicative, social/emotional, 
and personal/behavioral. In addition, there are certain areas of behavior 
that are applicable to specific age categories (i.e., responsiveness to 
stimuli; concentration, persistence, and pace). In these regulations, the 
term “developmental domains” is generally used when we 
discuss younger children * * *; the term “functional domains” 
is generally used when we discuss older children * * *.
This provision shows that the distinction between 
“developmental domains” and “functional domains” 
has reference only to age groups, not to the nature of the child's 
impairment, as the commenters seemed to have assumed. More importantly, 
the provision clearly states that the domains applicable at any age 
describe the child's functioning, the child's “major 
spheres of activity.” Thus, they encompass and reflect all that a 
child can and cannot do given his or her impairment(s), regardless of the 
nature of the impairment; they are not confined merely to 
“development.”
From the perspective of these rules, we think the commenters draw an 
artificial distinction between children with 
“developmental disabilities” and children with 
“physical disabilities” which these rules neither state nor 
imply. The commenters seem to believe that there is a distinction between 
conditions that may inherently limit or delay a child's 
“development” (e.g., mental retardation, cerebral palsy) and 
those that supposedly do not limit development but may limit a child's 
functioning (e.g., asthma, seizures, rheumatoid arthritis).
We do not maintain such a distinction in these rules because we believe 
that it would be artificial in the context of our program and that it has 
several flaws. The most obvious flaw is that many children who are 
regarded as “developmentally disabled” by other public laws 
and agencies have physical impairments as the basis of their developmental 
disabilities. Another flaw is in the implication that children with 
physical impairments are not affected in their development by their 
physical impairments. Certainly, all children with physical impairments 
cope differently with their impairments, depending on their individual 
capabilities and temperaments, and the nature of external support from 
their environments. But this is a highly relative matter, and it is likely 
that the development of all physically impaired children is affected to 
one degree or another.
The most important flaw in the distinction, however, is the implication 
that children with “developmental disabilities” and those 
with “physical 
disabilities” are somehow essentially different from one 
another—as if the things they are expected to do as children are 
altogether different. This is not the case. All children are expected to 
do the same things in childhood: to play, to learn to walk and talk, to 
learn to read and write, to live with adults and children, to learn to 
care for themselves, to become task-oriented. How well children do these 
things depends on their strengths and weaknesses, their skills and 
deficits, their abilities and limitations. However, because all children 
are expected to do these things, we evaluate each child from the 
perspective of the things that all children are expected to do.
Moreover, this is the perspective from which the Supreme Court directed us 
to evaluate functioning in children, to make 
“[a]n inquiry into the impact 
of an impairment on the normal daily activities of a child of the 
claimant's age[mdash ]speaking, walking, washing, dressing, and feeding 
oneself, going to school, playing, etc.  * * *.” 
Zebley, 110 S.Ct. at 896. The Court did not direct 
us to consider developmentally disabled children on the one hand and 
physically disabled children on the other.
These rules, therefore, require an evaluation of what the child is doing 
in all the major domains of functioning and behaviors appropriate to the 
child's age: physical, cognitive, communicative, social/emotional, etc. 
This determination is made irrespective of the nature of the child's 
impairment because the point is to determine the actual outcome of the 
impairment; that is, the impact on the child's functioning in practical, 
specific terms. For example, a child who has difficulty breathing and who 
experiences shortness of breath, or a child with limited strength and 
endurance may have difficulty keeping pace with peers at school; in such a 
case, a limitation in the area of concentration, persistence, or pace 
would be indicated. If a physical impairment causing a motor deficit 
limits a child's ability to engage in outdoor play, playground games, or 
sports, we would indicate some limitation in the motor domain. A child who 
has problems with eating, or who is susceptible to infection or other 
chronic illness, may be weakened by the condition or may experience pain; 
the functional effect of these symptoms could be manifested in diminished 
ability to concentrate, persist, or maintain pace, in social functioning, 
in motor functioning, or in any of the other domains or behaviors, 
depending on the specific impact the impairment has on the specific child. 
A child with a fine motor impairment that limits the ability to perform 
age-appropriate self-care activities (such as dressing), would have a 
limitation in the personal/behavioral domain. A child who has difficulty 
seeing or hearing may have problems in one or more of several functional 
areas, including cognitive, communicative, motor, social, and 
personal/behavioral. Thus, a physical impairment could cause limitation in 
any of the domains and behaviors considered in the evaluation of childhood 
disability and would be evaluated according to its impact on the child's 
functioning.
Finally, we do not believe that our use of the domains as an all-inclusive 
framework would confuse our adjudicators. Any programmatic approach to 
evaluating disability—in a child or adult—must necessarily be 
tied to a scheme of some kind that will allow adjudicators to organize 
information about how the impairment affects the person. We know from the 
past year-and-a-half of implementation experience that these rules have 
been effective and fair. The rules have provided adjudicators a means of 
organizing the information they obtain about child claimants from medical 
and nonmedical sources, employing functional domain terminology with which 
they already had some familiarity because we adopted it from the childhood 
mental listings. As we have said, we also believe that the rules provide a 
means of evaluating the effects of all impairments in all children, so it 
is also fair to the children. For this reason, we believe that we have 
made a difficult and complex task more manageable and less confusing than 
it would have been without such a framework.
Comment: One commenter suggested 
that we should add provisions that allow for nondevelopmental factors to 
be assessed outside the domains. The commenter also stated that, to the 
extent that domains are used in a determination, we should fully explain 
how they are being used, and that whenever examples are given in the 
rules, we should provide examples of physical impairments as well as 
developmental and mental disorder examples. The commenter also believed 
that the domains and criteria for age-appropriate activity should be 
revised to be more representative of children with physical impairments. 
For instance, this commenter and one other recommended that we revise 
§ 416.924c(a)(2) of the prior rules (final § 416.924d(c)) to 
state: 
“The following are domains of development, functioning and some of 
the specific behaviors and capacities that should be addressed in an 
individualized functional assessment * * * (viii) breathing; (ix) eating 
and eliminating; (x) seeing and hearing; (xi) ability to resist disease 
and function in the physical world (i.e., cope with the environment); 
(xii) strength and endurance; and (xiii) other physical and mental 
functions considered a part of normal function.” The two commenters 
also recommended changes in § 416.924c(c)(5), (d)(5), (e)(5), and 
(f)(5) of the prior rules to insert the word “functioning,” 
and a new sentence for § 416.924e of the prior rules to convey the 
idea that the domains were not all-inclusive.
Response: For the most part, we have 
not adopted the commenters' suggestions. We believe our response to the 
previous comments explains why it is unnecessary for 
“nondevelopmental 
factors” to be assessed outside the functional domains and 
behaviors that we use to assess children's impairments. We do not believe 
it is necessary for adjudicators to explain how the functional domains and 
behaviors are being used in any particular determination, because 
adjudicators use them in the manner described in the previous response and 
as appropriate to the case. We explain elsewhere that we do not believe 
examples are universally helpful to adjudicators because of the 
limitations inherent in generalizing an example to any specific case. 
However, in response to the commenter, we have added an example of a 
physical impairment to final § 416.924e(c)(2)(i). We have not revised 
the functional domains and behaviors to be “more representative of 
children with physical impairments” because, as we explained in the 
previous response, we do not distinguish categories of children in terms 
of the nature of their impairments but, rather, we evaluate all children 
in terms of the functional impact of their impairments.
In response to the commenter who recommended that we add several 
“specific 
behaviors and capacities” to the functional domains and behaviors 
in these rules, we do not believe it is appropriate to add capacities such 
as breathing, eating, eliminating, and strength as though they were 
separate and apart from the domains of functioning or specific behaviors 
that we consider for each age group. The domains and behaviors already 
take these limitations and impairment manifestations into account, not so 
much in terms of what they are, but in terms of how they affect the 
child's ability to function 
“independently, appropriately, and effectively in an 
age-appropriate manner” as shown by the things that the child 
actually does. Moreover, in response to the commenter who asked us to 
convey that the domains are not all-inclusive, we would say that, by 
definition in these rules, the domains and behaviors are all-inclusive and 
are intended to cover every possible activity a child may have. Finally, 
we could not adopt the other proposed language change in § 
416.924c(c) through (f) of the prior rules (final § 416.924d(g) 
through (i)) because “functioning” is not distinct from 
“adapting”: All children with all impairments (including 
physical) must adapt to their environments in order to function as 
effectively as possible in those environments.
Comment: One commenter who thought 
that the use of “domains” did not address physical 
impairments said that the determination of physical disability seems 
central to the notion of disability for adults and is clearly relevant to 
the functional assessment available to adults.
Response: We believe that we have 
made it clear that we agree with the comment and that these rules 
accomplish the same thing for children. The evaluation of disability in 
adults is more readily and observably divisible into physical and mental 
disability because the world of work activity is divisible into physical 
functions and mental functions, and the workplace is the context against 
which we must evaluate adults. The rules for the evaluation of disability 
in children are, in effect, more broadly based than the rules for the 
evaluation of adults because we must consider children in the context of 
their entire lives, 24 hours a day. This does not mean that the evaluation 
of physical disability plays a lesser role in the determination of 
disability for children. It means that the limitations imposed by a 
child's physical impairment(s) are evaluated in terms of the child's 
activities in all areas of living. This means that we assess a child's 
physical impairments in terms of all of the domains and behaviors and the 
myriad functions they subsume.
Comment: Two commenters observed 
that, even when a child's physical impairments do impede development, 
physicians and others are not accustomed to evaluating the impairments in 
developmental terms. For example, a child missing several fingers would 
not be described as having the fine motor developmental skills of a child 
half her age; she would merely be described as missing several fingers. 
Similarly, the impairments of children with asthma or cystic fibrosis are 
not described in developmental terms. Although these children may have 
marked restrictions in daily activities, “* * * most health care 
professionals consulted will not describe limitations in those terms.” 
Therefore, these commenters thought that, if we were going to use a 
“developmental model” for the assessment of impairment in all 
children, we must explain this decision to the public, the medical 
community, and the consulting examiners we employ, and must ask for such 
“developmental 
appraisals.”
Response: As we have explained, we 
do not use a developmental model. What we need to know is how the 
impairment(s) specifically affects the child's functioning, information 
that we will obtain from medical and nonmedical sources, for instance, how 
the child missing fingers on one hand is able to play, dress herself, feed 
herself, and so on. We will compare this information with the activities 
that are age-appropriate for the child and determine whether the child's 
impairment(s) substantially reduces his or her ability to do those things 
that are age-appropriate.
We should add, however, that the evidence we receive in documentation of 
the claims of young children (from birth to age 3, 4, or 5) often contains 
the results of screening and assessment devices used by pediatricians, 
early child development specialists, and therapists to evaluate a child's 
condition and to plan appropriate interventions. These measures of a 
child's growth and progress are often expressed in developmental terms, 
i.e., as a proportion of the child's chronological age. Even when a child 
has a physical impairment, a pediatrician, therapist, or other health care 
professional may evaluate the child in “developmental” terms, 
depending on the nature of the impairment and the purpose of the 
evaluation. For example, if a 3-year-old child who was missing several 
fingers required therapeutic intervention, an occupational therapist would 
be interested in assessing the extent (in terms of age level) of the 
child's motor skills in order to match the child's skill level with 
appropriate interventions.
Section 416.924e 
Guidelines for Determining Disability Using the Individualized Functional Assessment 
Comment: We received many comments 
stating the same four recommendations reflecting a general concern that 
the guidelines for the individualized functional assessment and 
accompanying examples might be applied rigidly or mechanically.
