504 Plan vs IEP: What's the Difference, and Which One Does My Child Need?
If you've just been handed a form or an evaluation and the school is throwing around "504" and "IEP," this guide gets you unstuck in about eight minutes.
The 30-second answer
A 504 Plan removes barriers so your child can access school — extra time, preferential seating, breaks. It's governed by Section 504 of the Rehabilitation Act.
An IEP (Individualized Education Program) does that and provides specially designed instruction and related services (speech, OT, resource room). It's governed by IDEA and comes with stronger procedural protections.
Side-by-side
| 504 Plan | IEP | |
|---|---|---|
| Law | Section 504 (civil rights) | IDEA (education law) |
| Eligibility | Any disability that substantially limits a major life activity | One of 13 IDEA categories that requires specialized instruction |
| Provides | Accommodations & access | Accommodations + specialized instruction + related services |
| Team | Small team, informal | Formal IEP team incl. gen-ed, special-ed, parent |
| Written plan required? | Recommended | Yes, legally required |
| Progress reporting | Not required | Required (usually quarterly) |
| Dispute options | OCR complaint, impartial hearing | Full IDEA procedural safeguards (mediation, due process) |
| Reevaluation | Periodic | Every 3 years (or sooner) |
How to pick a starting path
- Your child needs changes to how they access school (extra time, breaks, seating)? Start with 504.
- Your child needs changes to what is taught, or a service like speech or OT? You're likely looking at IEP.
- Not sure? Request a full evaluation in writing. That triggers IDEA timelines the school has to follow.
The 3 mistakes we see most
- Accepting a 504 when the child clearly needs services. Schools sometimes offer 504 because it's faster — ask directly whether an IDEA evaluation is warranted.
- Verbal accommodations only. If it's not written into the plan, it's not enforceable. Ever.
- Missing the 15-day PWN window. After any IEP meeting, the district must issue a Prior Written Notice. If they don't, that's your leverage.
