This report to Congress examines issues in the transition of students with disabilities into postsecondary education or employment. Major findings are: (1) most IDEA (Individuals with Disabilities Education Act) youth complete high school, but data on transitions are limited; (2) problems impeding the transition of IDEA youth into postsecondary education and employment remain partially addressed; and (3) the vocational rehabilitation, Workforce Investment Act, and Ticket programs provide transition services but several factors limit the number of IDEA youth who use them. Major recommendations of the report are: (1) gather and provide states with information on sound strategies to collect and use postsecondary data; (2) develop a plan to provide states with timely feedback and consistent quality of technical assistance; and (3) coordinate with other federal agencies to provide IDEA students and their families with information on federally funded transition services. The bulk of the document is comprised of nine appendices that include documentation of the scope and methodology of the study; state data collection efforts; state waiting lists for vocational rehabilitation services; youth eligible for the Ticket program; availability of Medicaid Buy-In to working people with disabilities; and comments from the Department of Education, Department of Labor, and the Social Security Administration.
