In this final rule, the Access Board is updating its existing Electronic and Information Technology Accessibility Standards under section 508 of the Rehabilitation Act of 1973, (“508 Standards”), as well as our Telecommunications Act Accessibility Guidelines under Section 255 of the Communications Act of 1934 (“255 Guidelines”). Given the passage of nearly two decades since their issuance, the existing 508 Standards and 255 Guidelines are in need of a “refresh” in several important respects. This final rule is intended to, among other things, address advances in information and communication technology that have occurred since the guidelines and standards were issued in 1998 and 2000 respectively, harmonize with accessibility standards developed by standards organizations worldwide in recent years, and ensure consistency with the Board's regulations that have been promulgated since the late 1990s. The Revised 508 Standards and 255 Guidelines support the access needs of individuals with disabilities, while also taking into account the costs of providing accessible information and communication technology to Federal agencies, as well as manufacturers of telecommunications equipment and customer premises equipment.
