Understanding IEP vs 504 Plans: Special Education Navigation
Both IEPs and 504 plans help students with disabilities succeed in public school, but they come from different federal laws. An IEP (Individualized Education Program) under IDEA provides specialized instruction and related services; a 504 plan under Section 504 of the Rehabilitation Act provides accommodations so a student has equal access to education.

How to request an evaluation
- Write to the school principal or special education director requesting a full evaluation in all areas of suspected disability
- Describe your concerns and any outside reports

- The school must obtain your written consent before evaluating, and under IDEA must complete the initial evaluation within 60 days of consent or the state's own timeline

Frequently asked questions
Can a child have both an IEP and a 504 plan?
Generally, a student with an IEP doesn't need a separate 504 plan because the IEP can include accommodations and the student is also protected under Section 504.
Do private schools have to provide IEPs?
Private schools are not required to provide IEPs, but under IDEA public school districts have obligations to identify and offer some services to eligible children in private schools in their area.
