OSEP National Longitudinal Studies
The U.S. Department of Education's Office of Special Education Programs (OSEP) has funded longitudinal studies to assess the Individuals with Disabilities Education Act (IDEA). The purpose is to influence policy and practice in support of improved results for children and youth with disabilities. Two OSEP longitudinal studies are child-based studies that relate specifically to young children with disabilities:
This 10-year longitudinal study (1997-2007) followed a nationally representative sample of 3,338 children and their families who began early intervention services in 1997-1998 through their experiences in early intervention and into early elementary school. Findings from the study provide information about the characteristics of children and families receiving early intervention services, the services they receive, and the outcomes they experience.
This study followed a group of children who received preschool special education services as they progressed through the early elementary years. The information from PEELS was to be used to help policymakers and researchers understand the variety and effectiveness of preschool special education programs.
