What is IDEA, the US special education law?
IDEA, the Individuals with Disabilities Education Act, is the main US federal special education law. It guarantees eligible children with disabilities a free appropriate public education (FAPE) in the least restrictive environment, with an Individualized Education Program (IEP), parent participation and procedural safeguards. Part B covers ages 3 to 21; Part C covers early intervention from birth to age 3.
What this means in practice
IDEA was first passed in 1975 as the Education for All Handicapped Children Act and has been reauthorized several times, most recently in 2004. It funds states and sets rules that every public school district must follow when identifying, evaluating and serving children with disabilities.
Six core principles
- Free appropriate public education (FAPE) at no cost to families.
- Appropriate evaluation before services and reevaluation over time.
- An Individualized Education Program for each eligible child.
- Least restrictive environment: learning with non-disabled peers to the maximum appropriate extent.
- Parent and student participation in decisions.
- Procedural safeguards, including dispute resolution and due process.
Who qualifies
A child must have one of 13 disability categories and, because of it, need special education and related services. Our page on the 13 IDEA categories lists them.
Why IDEA matters outside the US
IDEA influenced special education systems worldwide. Many international schools in the Gulf and Asia that follow American curricula use IDEA-style terms such as IEP, FAPE and LRE, so teachers there benefit from understanding it.

What to keep in mind
IDEA applies to US public schools. Private schools and schools in other countries follow their own laws and policies, though many borrow IDEA terminology.
