Generally, if an SLP's credentials were requested but not provided (and they cannot
be considered to exist per DI 22505.005B.1.), assume the SLP does not have any of the required credentials. However, the DDS
may contact the SLP for further information about credentials if it seems likely to
If credentials were not requested, but are relevant (i.e., the SLP's evidence could
potentially establish the existence of an impairment), the DDS may contact the individual
or institution and ask whether the SLP has any of the appropriate credentials.
Or, the DDS may elect to call the State professional licensing board, the SEA, or
ASHA, to ask whether the individual is State-professional-board-licensed, SEA-fully-certified
or has his/her CCC-SLP.
If these approaches are impractical, determine whether there is an impairment based
on evidence from an acceptable medical source, per DI 22505.003.
Remember that evidence that cannot establish the existence of an impairment may still
be very useful in assessing impairment severity.
