IEP vs. 504 plan: what's the difference?
Maybe a teacher mentioned a 504 at pickup, or the school offered one when you were expecting an IEP. The IEP vs 504 question comes down to different laws, different students and different rights for you as a parent or legal guardian.

The short answer
The main difference between an IEP and a 504 plan is what your child needs. An IEP, under IDEA, is for a child in one of IDEA's disability categories who needs specially designed instruction, and it includes goals and services. A 504 plan, under Section 504 of the Rehabilitation Act, is for a child whose disability substantially limits a major life activity and who mainly needs accommodations to access school. Neither one is a lesser version of the other.
"IEP vs 504" is one of the first questions parents and caregivers ask me. Is one better? Is the school offering less than my child needs? Those are fair questions. The simplest way I can put it: an IEP changes how your child is taught, and a 504 plan changes how your child gets to what everyone else is taught.
Both are free. Both are written by the school. Both are legally binding. The difference shows up in who qualifies, what goes into the plan, and what protections come with it.
What is an IEP?
An Individualized Education Program, or IEP, is a written plan under the Individuals with Disabilities Education Act (IDEA). Your child qualifies when two things are true. They have a disability in one of the categories IDEA lists (our guide to the 13 disability categories walks through them). And because of that disability, they need special education.
Special education here means specially designed instruction. That's teaching adapted in content, method or delivery to fit your child.
Federal rules spell out what an IEP must contain in 34 CFR 300.320. That includes your child's present levels of performance (see our guide to reading present levels), measurable annual goals, and how progress will be measured and reported to you. It also lists the special education and related services your child will get, any accommodations and modifications, and how much of the day your child will spend apart from students without disabilities.
What is a 504 plan?
A 504 plan comes from Section 504 of the Rehabilitation Act of 1973. It's a civil rights law. It bars discrimination against people with disabilities by any program that gets federal money, and that includes public schools.
A student qualifies when a physical or mental impairment substantially limits one or more major life activities. Since the ADA Amendments Act of 2008, the list of major life activities in 42 U.S.C. 12102 expressly includes learning, reading, concentrating, thinking and communicating.
That's a broader door than IDEA's. Picture a child with ADHD who's keeping up in class but loses focus without breaks, a child with diabetes who needs blood sugar checks during the day, or a child with anxiety who needs a plan for testing days. Each of them may qualify for a 504 plan without needing special education.
In practice, a 504 plan is mostly a list of accommodations. The Section 504 regulation at 34 CFR 104.33 does refer to "regular or special education and related aids and services," so a 504 plan can include things like counseling or health services. A child who needs specially designed instruction is usually evaluated for an IEP, though.
IEP vs 504 plan, side by side
| IEP | 504 plan | |
|---|---|---|
| Law | Individuals with Disabilities Education Act (IDEA), 34 CFR Part 300 | Section 504 of the Rehabilitation Act, 34 CFR Part 104 (the ADA also applies) |
| Who qualifies | A child in one of IDEA's disability categories who needs specially designed instruction because of it | A child with a physical or mental impairment that substantially limits a major life activity |
| What it includes | Present levels, measurable goals, special education, related services (speech, OT, PT, counseling), accommodations and modifications | Mostly accommodations; can include related aids and services |
| Who writes it | The IEP team, which must include the parent or legal guardian, a general education teacher, a special education teacher and a district representative | A group of people who know the child and the evaluation data; whether the parent or legal guardian takes part varies by district |
| Transition planning | Required in the IEP in effect when the child turns 16, or earlier if the team decides | Not required |
| Discipline protections | Manifestation determination before a disciplinary change of placement; services continue after 10 school days of removal in a year | An evaluation, including whether the behavior is caused by the disability, before a significant change in placement |
| Funding and oversight | Federal funding to states; enforced by the state education agency with federal oversight | No dedicated federal funding; enforced by the U.S. Department of Education's Office for Civil Rights |
| How often reviewed | IEP reviewed at least once a year; reevaluation at least every three years | "Periodic" reevaluation, plus before any significant change in placement; many districts review yearly by policy |
A few rows are worth a closer look. Transition planning comes from 34 CFR 300.320(b), which requires postsecondary goals and transition services starting with the first IEP in effect when your child turns 16. Annual review and the three-year reevaluation are in 34 CFR 300.324 and 34 CFR 300.303. The 504 reevaluation rule is in 34 CFR 104.35.
Discipline and your rights under each plan
A call about a suspension is hard to get. It helps to know the rules before that call ever comes.
Under IDEA, a school can remove a child with an IEP for up to 10 school days at a time, like any other student. Once a removal would change the child's placement, the school, the parent or legal guardian and relevant IEP team members must hold a manifestation determination within 10 school days. That meeting decides whether the behavior was caused by the disability or by the school's failure to follow the IEP. After 10 days of removal in a school year, the school has to keep providing services, even if the behavior wasn't a manifestation. All of this is in 34 CFR 300.530.
Section 504 requires an evaluation before any significant change in placement. The Department of Education's Office for Civil Rights treats an exclusion of more than 10 school days as a significant change, so the 504 team has to look at whether the behavior is related to the disability before a long suspension or expulsion (see the department's Section 504 FAPE questions and answers). Section 504 doesn't have a rule matching IDEA's requirement to keep providing services after removal.
Your rights differ too. IDEA gives you a detailed set of procedural safeguards: written notice, consent for evaluation and services, independent evaluations, mediation, state complaints and due process. Section 504 requires a shorter list in 34 CFR 104.36: notice, a chance to look at records, an impartial hearing and a review procedure. You can also file a complaint with the Office for Civil Rights (OCR).
A 504 plan is not a smaller IEP
A lot of caregivers hear "504" and feel like their child is getting the consolation prize. I understand that feeling. It isn't true, though.
A 504 plan is a different legal framework for students who need support but don't need specially designed instruction. If your child learns well once the barriers are out of the way, a well-written 504 plan may be exactly the right fit.
The trouble starts when the fit is wrong: if your child is falling further behind, if they aren't making progress with accommodations alone, if they need direct teaching in reading, writing, math, speech or behavior. A 504 plan can't hold what your child needs then.
Both plans have to give your child a free appropriate public education (FAPE). The IEP is the tool IDEA built for children who need instruction designed for them.
Which one fits your child?
You don't have to make this call on your own. Bring these questions to your team and sort out the 504 plan vs IEP decision together:
- Does my child need to be taught differently, or does my child need a different way to get to the same teaching?
- Is my child making progress in the general education curriculum with the supports already in place?
- Does my child need a service like speech therapy, occupational therapy or specialized reading instruction?
- Would my child benefit from measurable goals that are tracked and reported to me?
- Is my child old enough that transition planning for life after high school would help?
If most of your answers point toward teaching and services, ask for a full evaluation for special education. Put the request in writing and keep a copy.
If the school finds your child eligible for neither, ask for the decision in writing and ask what the team considered. That isn't the end of the road. Our post on what to do when your child isn't found eligible walks through your options, and the eligibility guide explains how the decision is made.
Getting help with the decision
I've spent over a decade as a speech-language pathologist in schools, outpatient clinics and private practice. I've run IEP meetings from the school's side of the table, and now I sit on yours.
If you're weighing a 504 plan against an IEP, or you have a 504 plan that doesn't seem to be working, I can review the documents with you and help you get ready for the meeting. You can read more on my 504 plan advocacy page. I'm not an attorney, and advocacy isn't legal advice. If you're heading toward due process or an OCR complaint, talk with a special education attorney.
