IEP vs 504 — which one does my child actually need?
Posted May 10, 2026
Quick primer for anyone new to this, then I'd love to hear how families decided which path to push for.
A 504 plan provides accommodations — changes to how a child accesses the regular curriculum (e.g., extra time, sensory breaks, preferential seating, noise-cancelling headphones).
An IEP is a legally binding plan that provides specialized instruction and related services — it can change what and how a child is taught (e.g., speech therapy at school, OT, social skills groups, modified curriculum).
A medical autism diagnosis does not automatically qualify a child for an IEP. The school team has to decide the disability impacts educational performance and that specialized instruction is needed. Some kids with autism do better with a 504; many benefit substantially more from an IEP.
My questions to the group:
- If you started with a 504 and later moved to an IEP (or vice versa), what triggered the change?
- For families whose district pushed back on an IEP eligibility — how did you advocate, and did you bring outside evaluations?
- Anyone with a child who has both? How do they coordinate in practice?
