IEP vs. 504 Plan: What's the Difference

Written by Casey, a Minnesota school counselor and former special education teacher.

IEPs and 504 plans both exist to support students with disabilities, and it's common for families to hear both terms without a clear sense of how they differ, or which one applies to their child. Here's the real distinction.

Different laws, different purpose

An IEP (Individualized Education Program) comes from IDEA, a special education law, and is for students who need specially designed instruction because of a disability -- meaning the way they're taught has to change, not just accommodated. A 504 plan comes from Section 504 of the Rehabilitation Act, a civil rights law, and is for students who have a disability that substantially limits a major life activity but who can access the general curriculum with accommodations rather than specialized instruction.

What each one actually provides

An IEP includes individualized goals, specially designed instruction, and often related services (like speech therapy or occupational therapy), all documented in detail and reviewed on a legal timeline. A 504 plan provides accommodations -- things like extended test time, preferential seating, or breaks -- without specially designed instruction or the same formal goal-writing and service structure an IEP requires.

Eligibility is not automatic either way

Having a diagnosis alone doesn't automatically qualify a child for either one. IEP eligibility requires falling into one of IDEA's specific disability categories AND needing specially designed instruction as a result. 504 eligibility is broader on the disability side (any impairment substantially limiting a major life activity can qualify) but doesn't require the specialized-instruction need an IEP does -- which is part of why a student who doesn't qualify for an IEP may still qualify for a 504 plan.

A student can move between them, or need both discussed

It's not unusual for a team to evaluate a student for an IEP and determine a 504 plan fits better instead, or vice versa, as needs change over time. If you believe your child needs specially designed instruction and currently only has a 504 plan, or vice versa, it's reasonable to ask the school in writing to evaluate for the other one directly.

This is general information, not legal advice, and isn't specific to your child's own IEP. For anything specific to your situation, talk with your child's IEP team or a special education attorney or advocate.
