The IDEA Data Center focuses on data requirements under Sections 616 and 618 of the Individuals with Disabilities Education Act, including data focused on programs for infants, toddlers, and their families (Part C) and on programs serving children ages 3 through 21 (Part B). Building capacity for high-quality IDEA data will affect states, school districts, and local early intervention programs across the nation. Those entities will, in turn, apply the higher quality data they generate to improve outcomes for all children and youth with disabilities served under IDEA.
