This paper summarizes information concerning the impact of three pieces of federal legislation on the inclusion of students with disabilities in postsecondary programs, especially those supported by the TRIO program. The paper briefly describes major points of the following laws: (1) the Individuals with Disabilities Education Act (IDEA), which is the basic special education law for K-12; (2) the Americans with Disabilities Act (ADA) of 1990, which prohibits discrimination on the basis of disability in employment; and (3) Section 504 of the Rehabilitation Act of 1973, which mandates equal access for students with disabilities at institutions with programs receiving federal aid. Specific ways in which TRIO programs can comply with and coordinate their efforts with these legal initiatives are noted, including educating parents regarding the rights of their children with disabilities, a careful distinction between guaranteeing equal access and guaranteeing student success (which is not required), provision of accommodations (such as sign language interpreters, note takers, extended time in testing), and general services (such as adapted housing and transportation).
