IDEA—40 Years Later

On Nov. 29, 1975, President Gerald Ford signed into law the Education for All Handicapped Children Act (Public Law 94-142), now known as the Individuals with Disabilities Education Act (IDEA). In adopting this landmark civil rights measure, Congress opened public school doors for millions of children with disabilities and laid the foundation of the country’s commitment to ensuring that children with disabilities have opportunities to develop their talents, share their gifts, and contribute to their communities.

In the last 40 years, we have advanced our expectations for all students, including students with disabilities. Classrooms have become more inclusive and the future of children with disabilities brighter. Significant progress has been made toward protecting the rights of, meeting the individual needs of, and improving educational results for infants, toddlers, children and youths with disabilities.

Today, according to the 2013 Child Count, over 62 percent of students with disabilities are in general education classrooms 80 percent or more of their school day, and early intervention services are being provided to over 340,000 infants and toddlers with disabilities and their families. Since 1975, we have gone from excluding nearly 1.8 million youths with disabilities from public schools to providing over 6.9 million students with disabilities special education and related services designed to meet their individual needs.

In 2015, we celebrate the 40th anniversary of the passage of Public Law 94-142. While tremendous progress has been made over the years, we must continue the hard work and address the challenges that still exist. Although we are able to help many individual students to achieve their goals, we must strive to ensure that all children have the support they need and to find ways to meet each student’s needs within the context of each school.

"Celebrating 40 Years of IDEA"


On Nov. 29, 1975, the passage of the Education for All Handicapped Children Act, now known as the Individuals with Disabilities Education Act (IDEA), guaranteed access to a free, appropriate, public education (FAPE) in the least restrictive environment to every child with a disability. Subsequent amendments, as reflected in the IDEA, have led to an increased emphasis on access to the general education curriculum, the provision of services for young children from birth to five, transition planning and accountability for the achievement of students with disabilities.


As part of our celebration of 40 years of the IDEA, we wanted to hear from individuals with disabilities—especially children and youth with disabilities—parents, teachers, researchers and all other IDEA stakeholders about the personal impact this law has had on them.

      • Results Driven Accountability (RDA)
        OSEP has revised its accountability system to shift the balance from a system focused primarily on compliance to one that puts more emphasis on results.


  • New Dear Colleague Letter on Free and Appropriate Public Education (FAPE)
  • The cornerstone of IDEA is the entitlement of each eligible child with a disability to a free appropriate public education (FAPE) that emphasizes special education and related services designed to meet the child's unique needs. The primary vehicle for providing FAPE is through an appropriately developed individualized education program (IEP) that is based on the individual needs of the child.This policy letter clarifies that IEPs for children with disabilities must be aligned with state academic content standards for the grade in which a child is enrolled.
