IDEA at 50—Progress, Equity, and the Work Ahead: The Editors

This year marks the 50th anniversary of the Individuals with Disabilities Education Act (IDEA), a landmark civil rights law born of advocacy and struggle that aimed to fundamentally reshape the landscape of public education in the United States. Enacted in 1975 as the Education for All Handicapped Children Act and later reauthorized as IDEA, the law affirmed a simple yet revolutionary premise: every child, regardless of disability, has the right to a free and appropriate public education (FAPE) in the least restrictive environment (LRE). Before IDEA, millions of children with disabilities were denied access to school, warehoused in institutions, or taught in segregated, inadequate classrooms. According to the U.S. Government Accountability Office (2019), only one in five students with disabilities were served in public schools in 1970. Today, more than 8 million students receive special education services under IDEA's protections (Office of Special Education and Rehabilitative Services, 2025).
