IEP vs. 504 Plan for Autism: What's the Difference?
The short answer
An IEP (Individualized Education Program) is created under IDEA and provides specialized instruction and related services, like speech or OT, with measurable goals. A 504 plan comes from Section 504 of the Rehabilitation Act and provides accommodations, like extra time or a quiet space, so a student can access general education. Many autistic students qualify for an IEP.

Side-by-side comparison
| IEP | 504 plan | |
|---|---|---|
| Law | Individuals with Disabilities Education Act (IDEA) | Section 504 of the Rehabilitation Act |
| Provides | Specialized instruction, related services, accommodations | Accommodations and modifications |
| Written goals | Yes, measurable annual goals | Not required |
| Who qualifies | One of 13 disability categories (autism is one) that affects educational performance and requires specialized instruction | Any disability that substantially limits a major life activity |
| Review | At least yearly; reevaluation at least every 3 years | Varies by district, typically yearly |
| Parent procedural rights | Detailed, written safeguards | Fewer formal safeguards |
How to decide which to ask for
If your child needs teaching delivered differently, or needs services like speech, OT, or social skills instruction, an IEP is usually the right request. If your child is doing well academically but needs adjustments, such as breaks, preferential seating, or noise-reducing headphones, a 504 plan may be enough.
- Put your request for an evaluation in writing and keep a dated copy.
- Share outside reports, such as the diagnostic evaluation and therapy notes.
- Ask the school to explain which plan they recommend and why, in writing.
- If you disagree, you can request an independent educational evaluation or use your state's dispute options.
Frequently asked questions
- Can a child have both an IEP and a 504 plan?
- Generally no. An IEP already includes accommodations, so students with an IEP do not usually need a separate 504 plan.
- Does an autism diagnosis automatically qualify my child for an IEP?
- No. The school must find that autism affects your child's education and that specialized instruction is needed. A diagnosis is strong supporting information, not automatic eligibility.
