IEP or 504 plan: which one does my child with autism need?

Two different laws, two different products. An IEP comes from IDEA and buys specialized instruction plus related services, and your child has to be found eligible under one of IDEA's disability categories, of which autism is one. A 504 plan comes from Section 504 of the Rehabilitation Act and buys accommodations and access, with wider eligibility and no requirement that the instruction itself change. A child can be autistic, not qualify for an IEP, and still be covered by a 504 plan.

What does an IEP actually give my child?

Specialized instruction designed around your child, plus the related services that let them access it, which can include speech therapy, occupational therapy, counseling or transportation. The federal rule on IEP contents requires measurable annual goals, a statement of the services the school will provide, how progress toward the goals will be measured, and how often you will be told about that progress. Eligibility has two parts, not one. Your child has to fit a disability category, autism among them, AND the disability has to mean the child needs special education. That second half is where districts say no to children whose grades look fine on paper.

What does a 504 plan give?

Access, not instruction. Section 504 is a civil rights law that bars disability discrimination in any program getting federal money, and in a public school it requires a free appropriate public education for a student with a disability. In practice a 504 plan is a written set of accommodations: extended time on tests, a quiet room, a sensory break, preferential seating, a printed schedule, a pass to leave a loud assembly, permission for headphones. Eligibility is broader than IDEA's because it turns on a disability that substantially limits a major life activity, not on a list of categories. What it does not do is change how your child is taught. That part only an IEP buys.

How do I request an evaluation?

In writing, dated, by email so you have a timestamp, addressed to the special education director with the principal copied. One sentence does it: I am requesting a full initial evaluation of my child for special education eligibility under IDEA, and I am requesting the consent forms. Do not ask verbally at pickup and hope. The district will send you a consent form, and your signature on that form starts the clock: the initial evaluation must be completed within 60 days of parental consent, unless your state has set its own timeframe. Keep every reply in one folder. If somebody tells you to wait and see, put their answer in writing back to them.

Am I on the team, or just informed?

You are on the team. The federal rule listing who must be on the IEP team names the parents of the child first, before the teachers and before the district representative. That is not a courtesy seat. You can ask for the draft goals before the meeting instead of reading them cold in the room. You can bring another person, including someone with knowledge of your child. You can ask for the meeting to be rescheduled to a time you can attend. And you can decline to sign at the table and take the document home to read. A meeting that pressures you to sign that day is telling you something about the district, not about your child.

What if the school says no?

A no is a decision, and decisions come with paper. Ask for prior written notice, which the district has to give you when it refuses to evaluate or refuses to change identification or placement, and which has to explain why it refused and what information it used. Read that explanation carefully, because it usually names the exact gap you need to fill, often data showing the disability affects school performance. Ask in the same email whether your child qualifies under Section 504 instead. Ask for the procedural safeguards notice. Independent evaluations, mediation and due process exist as next steps, and a parent training and information center in your state can walk you through them for free.

• Email a dated written request for a full initial special education evaluation to the special education director, copying the principal.
• Ask for the draft IEP or 504 goals in advance and read them before the meeting, not in it.
• If the answer is no, ask for prior written notice explaining why, and ask about Section 504 in the same email.
• Keep one folder with every evaluation, report, email and signed consent, in date order.
