Both provide protections, but only one guarantees specialized instruction. A plain-English comparison.
Parents are often steered toward a 504 plan because it is faster to write. Faster isn't the same as sufficient.
The core difference
- An IEP provides specially designed instruction, measurable goals, and progress reporting under IDEA.
- A 504 plan provides access — accommodations that remove barriers — under civil rights law.
- An IEP requires eligibility under one of the disability categories and a demonstrated educational need.
- A 504 plan requires a disability that substantially limits a major life activity.
How to decide
If your child needs someone to teach a skill differently, that is instruction and belongs in an IEP. If your child can access the curriculum with adjustments — extended time, seating, medical supports — a 504 may be enough. When in doubt, request the evaluation; you can always accept a 504 afterward.
