This website provides public access to data about children and youth with disabilities served under the Individuals with Disabilities Education Act (IDEA) - Part B and C; technical assistance (TA) materials to support the collection, analysis and reporting of IDEA data; and the forms and spreadsheets used for collection.
DAC was funded in October 2007 by the Office of Special Education Programs (OSEP), U.S. Department of Education to provide information and TA to improve the quality of all state-reported data required by the IDEA.
Westat and its subcontractor, Louisiana State University Health Sciences Center–Human Development Center, operated DAC as a 5-year cooperative agreement with OSEP through September 30, 2012.
Between October 1, 2012 and September 30, 2013, Westat will maintain this website, but will not be producing new technical assistance materials or providing individual technical assistance to states.
