What does Section 508 of the Rehabilitation Act of 1973 require?

Section 508 of the Rehabilitation Act Amendments of 1998 (§508) requires that:

[w]hen Federal agencies develop, procure, maintain, or use electronic and information technology, Federal employees with disabilities have access to and use of information and data that is comparable to the access and use by Federal employees who are not individuals with disabilities, unless an undue burden would be imposed on the agency. Section 508 also requires that individuals with disabilities, who are members of the public seeking information or services from a Federal agency, have access to and use of information and data that is comparable to that provided to the public who are not individuals with disabilities, unless an undue burden would be imposed on the agency.

Section 508 also requires federal agencies to ensure that all electronic and information technology they procure, develop, maintain, or use complies with the accessibility standards developed by the Architectural and Transportation Barriers Compliance Board (Access Board).
