IEP vs. 504 Plan: Side-by-Side Comparison for Parents

An IEP provides specialized instruction and legally mandated services under IDEA — it changes how your child is taught. A 504 Plan provides accommodations for equal access under Section 504 — it changes the conditions around learning without specialized instruction. Children who need specialized teaching need an IEP; children who only need accommodations may qualify for a 504.

This guide breaks down exactly what each one is, how they're different, and how to figure out which one is right for your child.

The One-Sentence Version

An IEP provides specialized instruction tailored to your child. A 504 Plan provides accommodations so your child can access the same instruction as everyone else.

That's the core distinction. Everything else flows from it.

What Is an IEP?

An Individualized Education Program (IEP) is a legally binding document created under the Individuals with Disabilities Education Act (IDEA). It's designed for children who need specially designed instruction — meaning the way they're taught needs to be adapted to meet their unique needs.

An IEP includes:

• Present Levels of Performance — where your child is right now, academically and functionally
• Measurable annual goals — specific targets your child should work toward
• Specially Designed Instruction (SDI) — teaching methods adapted specifically for your child
• Related services — things like speech therapy, occupational therapy, counseling, or behavioral support
• Accommodations and modifications — changes to how or what your child learns
• Progress monitoring — how and when the school will measure and report your child's progress

To qualify for an IEP, your child must:

1. Have a disability that falls under one of IDEA's 13 eligibility categories
2. That disability must meaningfully impact their ability to learn at school
3. Your child must need specially designed instruction (instruction specifically adapted for your child's disability) as a result

All three must be true. A diagnosis alone doesn't automatically qualify a child for an IEP.

What Is a 504 Plan?

A 504 Plan is created under Section 504 of the Rehabilitation Act of 1973 — a civil rights law that prevents discrimination against people with disabilities. It's designed for children who have a disability that substantially limits a major life activity (like learning, reading, concentrating, or walking) but who may not need specialized instruction.

A 504 Plan provides accommodations — changes to the learning environment or how material is delivered so your child can access education on an equal footing.

Common 504 accommodations include:

• Extended time on tests
• Preferential seating
• Breaks during long assignments
• Permission to use a calculator or assistive technology
• Modified homework load
• Access to notes or recorded lectures

To qualify for a 504 Plan, your child must:

1. Have a physical or mental impairment that
2. Substantially limits one or more major life activities

The eligibility criteria are broader than an IEP. Many children who don't qualify for an IEP do qualify for a 504.

Side-by-Side Comparison

Feature	IEP	504 Plan
Federal law	IDEA (Individuals with Disabilities Education Act)	Section 504 of the Rehabilitation Act
Purpose	Provide specialized instruction and services	Provide accommodations for equal access
Eligibility	Must meet one of 13 disability categories AND need specially designed instruction	Any physical or mental impairment that substantially limits a major life activity
What it provides	Modified instruction, related services, accommodations, and modifications	Accommodations only (no modified instruction or related services)
Written document	Yes — detailed, with specific goals and progress monitoring	Yes — but format varies by district (often less detailed)
Annual review required	Yes	Yes (though enforcement varies)
Reevaluation	Every 3 years (or sooner if requested)	Periodically (varies by district)
Parent participation	Required by law — parents are part of the IEP team	Recommended but not always required in the same way
Due process protections	Strong — includes mediation, due process hearings, stay-put provisions (see full IEP rights guide)	More limited — complaint process through OCR (Office for Civil Rights)
Funding	School receives federal funding for IEP services	No additional funding — school absorbs costs

Common Scenarios: IEP or 504?

Here's how this plays out in real life.

Scenario 1: ADHD with academic struggles

Your child has ADHD. Grades are slipping, homework takes hours, and the teacher says they "can't focus."

Could go either way. If your child needs accommodations like extra time and preferential seating — a 504 may be enough. But if ADHD is significantly impacting learning and your child needs specially designed instruction (like modified assignments, behavioral interventions, or executive functioning support) — an IEP under the category "Other Health Impairment" may be more appropriate.

Scenario 2: Dyslexia

Your child has been diagnosed with dyslexia and is reading two grade levels behind.

Likely an IEP. Dyslexia typically requires specialized reading instruction (like Orton-Gillingham or Wilson Reading) — not just extra time on tests. That's specially designed instruction, which means an IEP.

Scenario 3: Anxiety disorder

Your child has a diagnosed anxiety disorder. They have panic attacks during tests and avoid school on presentation days.

Start with a 504. Accommodations like a quiet testing space, the ability to leave the room when overwhelmed, or modified presentation requirements may be enough. If anxiety is so severe that it's preventing your child from accessing the curriculum even with accommodations, escalate to an IEP evaluation.

Scenario 4: Physical disability

Your child uses a wheelchair but has no cognitive or learning differences.

504 Plan. Your child needs physical accommodations (accessible classroom, modified PE, elevator access) but doesn't need specialized academic instruction.

Can Your Child Have Both?

Not exactly. An IEP already includes everything a 504 can provide — accommodations, modifications, and more. If your child qualifies for an IEP, the 504 is essentially absorbed into it.

However, if your child had a 504 and now qualifies for an IEP, the transition is common. And if your child is evaluated for an IEP but doesn't qualify, you should immediately ask: "Does my child qualify for a 504 Plan instead?"

What If the School Suggests the Wrong One?

This happens more than it should. Some common patterns:

• School offers a 504 when an IEP is needed — sometimes because a 504 requires fewer resources and less paperwork. If your child needs specialized instruction (not just accommodations), push for an IEP evaluation.
• School says your child "doesn't qualify" for either — you have the right to request an evaluation in writing. The school must respond. If they refuse, they must provide Prior Written Notice (PWN) explaining why.
• School suggests dropping the IEP to a 504 — this sometimes happens when a child is "doing well." But ask: Are they doing well because of the IEP supports? Removing the IEP could remove the very thing that's working.

Your Next Steps

1. If your child doesn't have either: Request an evaluation in writing. The school must respond within a set timeline (varies by state).
2. If your child has a 504 but is struggling: Request an IEP evaluation. A 504 might not be enough.
3. If someone suggests changing from IEP to 504: Ask for data showing your child would maintain progress without specialized instruction.
4. If you're not sure what your child has: Request a copy of the current plan. Read it. If it has goals and specially designed instruction, it's an IEP. If it lists accommodations only, it's a 504.
