The State(s) of Early Intervention and Early Childhood Special Education: Looking at Equity is the first equity-focused report to look state-by-state at the two federally funded programs for young children with disabilities. Our report investigates variations in access to (1) Early Intervention (EI) for children birth to age 3 and (2) Early Childhood Special Education (ECSE) for children 3 to 5 not yet in kindergarten. We primarily examine data from the 2020-2021 school year but also examine trends from 2005-2006 to 2020-2021. In addition to investigating variations in access to services per se, this report also looks at variations in how services are provided. For EI this is whether children are served in the natural environment. For ECSE, this is whether children are served in their least restrictive environment (LRE). Under IDEA, young children are entitled to a free and appropriate public education (FAPE) in the natural or least restrictive environments to the maximum extent possible. (author abstract)
