Each State VR agency in collaboration with the DDS should refine its screening criteria,
            using these guidelines as a base. The SSA regional office should be provided a copy
            of the guidelines adopted. The screening and referral criteria in these guidelines
            may be expanded, supplemented, or adjusted to an individual State agency situation.
            However, the subject items as listed in each category (i.e., screen-out criteria,
            screen-in criteria and applicant profile should be retained). Additionally, the State
            VR agency should inform the DDS of projects and studies conducted in special fields
            such as the rehabilitation of the hearing impaired, epileptics, arthritics, or other
            special impairment groups, and should request the DDS to make the appropriate referrals.
            The DDS (or State VR agency, shall provide a copy of the screening criteria used to
            the respective Regional Office for transmittal to the central office whenever any
            change in the criteria is made. See DI 28087.015C.
