The purpose of this part is to implement the Age Discrimination Act of 1975 (“Act”), as amended, and as required by the general age discrimination regulations at 45 CFR part 90. The Age Discrimination Act of 1975, as amended, is designed to prohibit discrimination on the basis of age in programs or activities receiving Federal financial assistance. The Act also permits federally assisted programs or activities, and recipients of Federal funds to continue to use certain age distinctions and factors other than age which meet the requirements of the Act and the regulations in this part.
