An IEP — Individualized Education Program — is a legally binding plan that a U.S. public school must create for an eligible child who needs special education. Autistic students who need special education services qualify under federal law (IDEA), and any family or teacher can start the process by asking the school in writing for an evaluation.

What does an IEP do?

An IEP is the document that says exactly what services, supports, and goals a school will provide for one specific student. It is written by a team that includes the parents (or caregivers), the student when appropriate, at least one general-education teacher, at least one special-education teacher, and a school representative who can commit district resources.

Every IEP must include the student’s present levels of academic and functional performance, measurable annual goals, the specific special-education and related services the school will provide, any accommodations, the percentage of time the student will spend with non-disabled peers, and — once the student is 16 — a transition plan for life after high school.

Which law makes IEPs happen?

The Individuals with Disabilities Education Act, almost always called IDEA, is the federal law that requires public schools to provide a free appropriate public education to eligible children with disabilities, in the least restrictive environment. IDEA has been in effect in some form since 1975 and is administered by the U.S. Department of Education’s Office of Special Education Programs.

Autism is one of 13 disability categories under IDEA. A child is eligible if (1) they meet the criteria for one of those categories and (2) the disability affects educational performance in a way that requires specially designed instruction. The diagnosis alone is not enough — the school must determine educational need.

How do you start the process?

Anyone — a parent, a teacher, a doctor, or the student — can ask the school to evaluate a child for special education. The strongest first step is a short letter or email to the school’s special-education coordinator or the principal. Keep a copy. The letter does not need to be formal. A working example:

I am requesting a full and individual evaluation under IDEA to determine whether my child, [name], is eligible for special education and related services. Please send me the consent forms and the procedural safeguards notice.

Once the school receives a written request, federal regulations require the school to either start the evaluation or give the family a written notice explaining its refusal. State timelines vary, but most states require the evaluation to be completed within roughly 60 days of consent.

What happens at the evaluation?

A multidisciplinary team gathers information from many sources — classroom observations, teacher input, standardized testing, speech and occupational evaluations as needed, and information from the family. The school cannot rely on a single test or measure to decide eligibility.

If the child is found eligible, the team holds an IEP meeting (usually within 30 days of the eligibility decision) to write the first IEP. If the family disagrees with the school’s evaluation results, they can request an Independent Educational Evaluation at public expense.

What rights do families have?

IDEA gives families — called “parents” in the law — substantial procedural rights, summarized each year in a document called the Procedural Safeguards Notice. The main ones:

  • Prior written notice. The school must tell parents in writing before it proposes or refuses to change identification, evaluation, or placement.
  • Consent. The school cannot evaluate or initially place a child in special education without parent consent.
  • Access to records. Parents can inspect and copy their child’s education records.
  • Meaningful participation. Parents are equal members of the IEP team. Meetings must be scheduled at a mutually agreeable time.
  • Dispute resolution. If the family and school disagree, families can request mediation, file a state complaint, or file for due process.

How is an IEP different from a 504 plan?

A 504 plan comes from Section 504 of the Rehabilitation Act, a civil-rights law. It guarantees a student equal access to school but does not provide specially designed instruction. An IEP, under IDEA, includes specially designed instruction and related services such as speech therapy, occupational therapy, or behavioral supports. Many autistic students who need only environmental accommodations — preferential seating, sensory breaks, extended time — have a 504 plan. Students who need direct instruction tailored to how they learn typically have an IEP.

How often is an IEP reviewed?

The IEP team must review the IEP at least once a year. The school must reevaluate the child for continued eligibility at least every three years (the “triennial”), unless the parent and the school agree the reevaluation is not necessary. Families can request a new IEP meeting at any time if the current plan is not working.

What if the school says no?

If the school refuses to evaluate, the family is entitled to prior written notice explaining the refusal. Families can then file a state complaint with their state department of education, request mediation, or file for due process. Every state also has a federally funded Parent Training and Information Center that provides free help navigating the process.
