The IDEA National Assessment Implementation Study Restricted Use File (RUF) contains survey data and documentation from the Individuals with Disabilities Education Act National Assessment Implementation Study (IDEA-NAIS). The IDEA-NAIS is a descriptive study based primarily on four surveys that provide a comprehensive national picture of the state agency and school district implementation of IDEA across the 2008-2009 school year. All state agencies and a nationally representative set of 1,200 school districts were surveyed. The RUF can be accessed through a restricted use license agreement with the National Center for Education Statistics.
