Federal policy has long played a key role in how the more than seven million children with disabilities are educated, but the context for the policies has been shifting. This compendium describes the methods, response rates, and weights used for surveys of state, district, and school agency personnel about implementation of the Individuals with Disabilities Education Act in the 2019–2020 school year. It also includes detailed tables, based on the surveys, that provide a national picture of policies and practices, 15 years after the law was last updated and 10 years after a similar study was conducted.
