The report is organized to provide information on the school-level implementation of alternate assessments for students with significant cognitive disabilities. Following the Introduction in Chapter 1, Chapter 2 describes the study design and methods, including the development of the teacher survey and data collection procedures and analyses.…

This paper provides a guide to calculating statistical power for the complex multilevel designs that are used in most field studies in education research. For multilevel evaluation studies in the field of education, it is important to account for the impact of clustering on the standard errors of estimates of treatment effects. Using ideas from…

The Study of Monitoring and Improvement Practices under the Individuals with Disabilities Education Act (IDEA) examined how states monitored the implementation of IDEA by local special education and early intervention services programs.

The National Longitudinal Transition Study-2 (NLTS2) is a 10-year-long study of the characteristics, experiences, and outcomes of a nationally representative sample of youth with disabilities who were 13 to 16 years old and receiving special education services in grade 7 or above, under the Individuals With Disabilities Education Act (IDEA) in the…

The National Center for Special Education Research (NCSER) at the Institute of Education Sciences (IES) is conducting a 5-year evaluation of states' monitoring and improvement practices under the "Individuals with Disabilities Education Act" ("IDEA"). The ultimate goal of this evaluation is to provide information to the Office of Special…

The Pre-Elementary Education Longitudinal Study, commonly referred to as the PEELS study, is funded by the U.S. Department of Education's National Center for Special Education Research (NCSER). It will follow a nationally representative sample of children with disabilities ages 3-5 for a period of six years. This study is designed to describe the…

This is the second in a series of NLTS2 fact sheets focusing on the experiences and outcomes of youth in a specific disability category. Students with learning disabilities comprise almost two-thirds of those receiving special education services in secondary schools. The majority of these students spend at least part of their day in a general…

Data from the National Longitudinal Transition Study-2 (NLTS2) are designed to provide a national picture of the rate at which secondary school students with disabilities complete high school and how they fare in their early postschool years. Further, comparisons of findings from NLTS2 and the original NLTS enables an investigation of changes in…

The Office of Special Education Programs (OSEP) of the U.S. Department of Education is working to provide the information needed to improve the transition and postschool outcomes of secondary school students with disabilities, in part through the National Longitudinal Transition Study-2 (NLTS2).
