The Individuals with Disabilities Education Improvement Act of 2004 (IDEA 2004) is the most recent authorization of a law passed in 1975 to promote a free appropriate public education for children with disabilities. Funded at $12.6 billion in Fiscal Year 2012, IDEA supports early intervention services for infants and toddlers, special education services for children ages 3 through 21, and early intervening services for students not in special education but in need of academic or behavioral support.
The focus of this study—conducted as part of the National Assessment of IDEA under Section 664 of IDEA 2004 to assess the implementation and effectiveness of key programs and services supported under the law—was on the inclusion of students with disabilities (SWDs) in school accountability systems and the variation in school practices in schools accountable and schools not accountable for the performance of the students with disabilities (SWD) subgroup under the Elementary and Secondary Education Act.
This evaluation relied on descriptive statistics to study patterns of school accountability across states and over time and to examine how school practices varied with school accountability for the SWD subgroup. Data sources for the evaluation included extant data from the U.S. Department of Education's EDFacts database and 2011 surveys of principals and special education designees from elementary and middle schools in 12 states.
A final report, titled School Practices and Accountability for Students With Disabilities, was released in February 2015.
