24 C.F.R. § 8.12

(a) A recipient may not use any employment test or other selection criterion that screens out or tends to screen out individuals with handicaps or any class of individuals with handicaps unless:

(1) The recipient demonstrates that the test score or other selection criterion, as used by the recipient, is job-related for the position in question; and

(2) The appropriate HUD official demonstrates that alternative job-related tests or criteria that tend to screen out fewer individuals with handicaps are unavailable.

(b) A recipient shall select and administer tests concerning employment to ensure that, when administered to an applicant or employee who has a handicap that impairs sensory, manual, or speaking skills, the test results accurately reflect the applicant's or employee's job skills, aptitude, or whatever other factor the test purports to measure, rather than 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).
