28 CFR 42.512 - Employment criteria.
(a) A recipient may not use any employment test or other selection criterion that tends to screen out handicapped persons unless:
(1) The test score or other selection criterion, as used by the recipient, is shown to be job-related for the position in question, and
(2) Alternative job-related tests or criteria that tend to screen out fewer handicapped persons are not shown by the appropriate Department officials to be available.
(b) A recipient shall administer tests using procedures (e.g., auxiliary aids such as readers for visually-impaired persons or qualified sign language interpreters for hearing-impaired persons) that accommodate the special problems of handicapped persons to the fullest extent, consistent with the objectives of the test. When a test is administered to an applicant or employee who has a handicap that impairs sensory, manual, or speaking skills, the test results must accurately reflect the applicant's or employee's job skills, aptitude, or whatever other factor the test purports to measure, rather than reflecting the applicant's or employee's impaired sensory, manual, or speaking skills (except where those skills are the factors that the test purports to measure).
