Welcome to the Web site for The Study of State and Local Implementation and Impact of the Individuals with Disabilities Education Act (SLIIDEA).  Conducted by Abt Associates Inc. with its subcontractors Westat and SRI, for the U.S. Department of Education's Office of Special Education Programs, SLIIDEA will examine how the Amendments of the Individuals with Disabilities Education Act (IDEA) of 1997 are being implemented by states, school districts, and schools.  In particular, it will address issues focused on student performance, access to the curriculum, behavioral supports, parental involvement, and transitions for young children to school and youth to adult life.  For more information, visit the Study Description page.

New Reports! A full report, 8-page summary report, and a presentation entitled Improving Results for Students with Disabilities: Key Findings from the 1997 National Assessment Studies are now available on the Reports page. The reports and presentation provide a synthesis of key findings that have emerged to date across the currently available data from the seven OSEP-funded national assessment studies that followed the reauthorization of IDEA in 1997.

The two final reports from the Study of State and Local Implementation and Impact of IDEA, the SLIIDEA Sourcebook Report and Marking the Progress of IDEA Implementation, are now available on the Reports page.
