This guide breaks down the difference between IEP and 504 plan in plain language, with a side-by-side comparison, eligibility rules for both, and a simple decision framework you can use in your next meeting. Whether you call it IEP versus 504, 504 plan or IEP, or just trying to understand the difference in 504 and IEP , it's all the same question, and you'll have a clear answer by the end of this guide.

IEP vs 504 Plan: The Quick Answer

An IEP (Individualized Education Program) is a legal document under IDEA that provides specialized instruction and related services for students with one of 13 qualifying disabilities. A 504 plan, governed by Section 504 of the Rehabilitation Act, provides accommodations and access to the general education curriculum for students with any disability that substantially limits a major life activity. Every student with an IEP is also automatically protected under Section 504, but most 504 students do not qualify for an IEP, the eligibility bar is broader for 504 plans and the services are limited to accommodations.

What Is an IEP?

An Individualized Education Program is a legal document that defines the specialized instruction, related services, accommodations, and goals for a student who qualifies for special education under the Individuals with Disabilities Education Act (IDEA). It is a contract between the school and the family. Every public school student who qualifies must have one, and the school must follow it.

About 7.5 million students roughly 15% of all public school students in the US, currently have an active IEP, according to the most recent data from the National Center for Education Statistics. That number has grown every year since 2010, and the percentage of students receiving special education services is at an all-time high.

An IEP includes:

• Present Levels of Academic and Functional Performance (PLAAFP) — where the student is right now, with specific data

• Annual goals — what the student will work toward over the next year, written as measurable SMART goals

• Special education services — specialized instruction the student will receive

• Related services — speech therapy, occupational therapy, counseling, transportation, anything else needed

• Accommodations and modifications — how the student will access general education

• Participation in general education — how much time the student spends in regular classrooms

• Assessment information — how the student participates in state and district testing

• Transition planning — for students 16 and older, plans for life after high school

The IEP team meets at least once a year to review and update the document. Every three years the school must conduct a full reevaluation to confirm the student still qualifies.

If you write IEP goals as part of your role, our step-by-step guide to writing SMART IEP goals walks through the process and includes examples by subject area.

What Is a 504 Plan?

A 504 plan is a written plan that lists the accommodations a student needs to access the general education curriculum. It comes from Section 504 of the Rehabilitation Act of 1973, which is a civil rights law prohibiting discrimination on the basis of disability in any program that receives federal funding, including every public school in the country. The Section 504 Rehabilitation Act applies to all federally-funded institutions, not just K-12 schools.

About 1.6 million US students, roughly 3% of all public school students, currently have a 504 plan, according to the most recent Civil Rights Data Collection from the US Department of Education's Office for Civil Rights. That number has nearly tripled in the last decade as more families have learned the plan exists.

A 504 plan typically includes:

• The disability or impairment that qualifies the student

• How that disability affects the student's learning or access to school

• Accommodations the student needs (extended time, preferential seating, frequent breaks, modified assignments, etc.)

• Who is responsible for providing each accommodation

• How and when the plan will be reviewed

A 504 plan does not include specialized instruction. It does not include annual academic goals. It is much shorter than an IEP , sometimes a single page. The point is to remove barriers, not to redesign the student's education.

IEP vs 504: Side-by-Side Comparison

Here's a clear comparison of the two plans across the criteria that matter most.

This is the comparison most teachers need on a Post-it note. Save it.

Which Students Qualify for an IEP?

To answer the common question "what qualifies a child for an IEP", the student must meet two requirements under IDEA:

1. The student must have one of these 13 disability categories:

• Specific Learning Disability (the largest category - includes dyslexia, dyscalculia, dysgraphia)

• Speech or Language Impairment

• Other Health Impairment (often where ADHD falls if it affects educational performance)

• Autism Spectrum Disorder

• Developmental Delay (for younger children)

• Emotional Disturbance

• Intellectual Disability

• Multiple Disabilities

• Hearing Impairment

• Orthopedic Impairment

• Visual Impairment (including blindness)

• Traumatic Brain Injury

• Deaf-Blindness

2. The disability must adversely affect the student's educational performance to the point that the student needs specially designed instruction.

This second requirement is the one that trips up most parents and new teachers. A student can have a documented disability and still not qualify for an IEP if that disability is not significantly affecting their access to learning. A student with mild dyslexia who reads at grade level with no support does not need an IEP. A student with the same diagnosis who reads two grade levels behind does.

The qualification process requires a full multidisciplinary evaluation. The school must get written parent consent before testing. The team, which includes the parent , meets to review the results and decide eligibility. The full process from referral to IEP in place typically takes 60-90 days.

Which Students Qualify for a 504 Plan?

The eligibility bar for a 504 plan is broader and lower. A student qualifies if they have a physical or mental impairment that substantially limits one or more major life activities. Major life activities include learning, reading, concentrating, thinking, communicating, walking, seeing, hearing, breathing, sleeping, eating, and the operation of major bodily functions.

This broader definition is why 504 plans cover students with conditions that don't fit IDEA's 13 categories, such as:

• ADHD that doesn't significantly impact academic performance but affects focus and behavior

• Anxiety disorders that interfere with test-taking or attendance

• Type 1 diabetes (needs blood sugar monitoring, snacks, bathroom access)

• Severe food allergies (needs an EpiPen plan and lunchroom accommodations)

• Asthma (may need inhaler access, modified PE)

• Epilepsy (needs seizure response plans)

• Concussions and recovery from traumatic injuries

• Cancer treatment side effects

The qualification process is much simpler than for an IEP. There's no formal multidisciplinary evaluation required. The 504 team reviews medical documentation, school records, and teacher input, then makes a decision. The whole process can take a few weeks rather than months.

Easterseals and the US Department of Education's Office for Civil Rights both publish detailed guidance on 504 eligibility if you need to look up specific cases.

How to Decide: IEP or 504?

Here's a simple framework. Ask three questions in order.

Question 1: Does the student need specialized instruction to learn?

If yes — meaning the student needs the curriculum, the teaching approach, or the materials modified beyond simple accommodations — start an IEP referral. Specialized instruction is the hallmark of an IEP. If a student needs to be taught differently from peers, not just supported with accommodations, they likely need an IEP.

If no — the student can access grade-level curriculum with the right supports — go to question 2.

Question 2: Does the student have a disability that substantially limits a major life activity?

If yes — the student has a documented impairment that affects how they learn, behave, or function at school — they likely qualify for a 504 plan.

If no — the student does not need either plan, but may benefit from informal classroom supports, an MTSS or RTI intervention, or general education differentiation strategies.

Question 3: Is the student's progress monitored over time?

If a student starts on a 504 plan but their needs grow more complex or their academic gap widens, they may need to be reevaluated for an IEP. Movement between the two is common. A student who starts with simple accommodations may discover they need specialized instruction once those accommodations stop being enough.

Common IEP and 504 Accommodations

This is where the practical work happens. Here are the most common accommodations you'll see on both types of plans, with notes on where each typically appears.

Common IEP accommodations:

• Extended time on tests and assignments (typically 1.5x or 2x)

• Preferential seating, often near the teacher or away from distractions

• Reduced assignment length (still covering the same standards)

• Use of assistive technology (text-to-speech, speech-to-text, calculators)

• Frequent breaks during instruction

• Visual schedules and graphic organizers

• Modified assessments or alternate assessments

• Specialized instruction in resource rooms or co-taught classrooms

• Behavior intervention plans (BIPs) for students with behavior goals

• Related services like speech therapy, OT, PT, and counseling

IEP accommodations also come with the legal requirement that students learn in the least restrictive environment — meaning they should be in general education classrooms with their peers as much as possible, only pulled out for specialized services when absolutely necessary.

Common 504 accommodations:

• Extended time on tests

• Preferential seating

• Permission to leave class for medical needs (insulin checks, EpiPen access, restroom breaks)

• Modified attendance policies for chronic illness

• Access to water and snacks during class

• Note-taking assistance or copies of class notes

• Use of a calculator or word processor

• Access to a school nurse on scheduled basis

• Modified PE or alternative physical activity options

• Quiet testing environment

504 Accommodations for ADHD

ADHD is one of the most common reasons a student gets a 504 plan. Common 504 plan ADHD accommodations include extended time on tests, preferential seating, frequent movement breaks, broken-down assignments, written and verbal directions, and check-ins from the teacher to monitor focus. Some students with ADHD qualify for an IEP under "Other Health Impairment" if their ADHD significantly affects their ability to access the curriculum — but most ADHD students are served through 504 plans.

The key difference: an IEP would also include specialized instruction targeting the student's executive functioning and self-regulation skills as measurable goals. A 504 plan stops at the accommodations.

Your responsibilities as a classroom teacher differ for each plan, but both come with legal weight.

For students with an IEP, you must:

• Read the entire IEP at the start of the year and any time it is updated

• Implement every accommodation and modification listed

• Collect data on progress toward annual goals

• Communicate with the case manager or special education teacher regularly

• Attend IEP meetings when requested (this is part of your job)

• Document any concerns or changes you observe

• Never modify or remove accommodations without team approval

For students with a 504 plan, you must:

• Read the entire 504 plan at the start of the year

• Implement every accommodation listed

• Communicate with the 504 coordinator if accommodations aren't working

• Document the use of accommodations if your district requires it

• Treat the plan as legally binding — it is

If you feel a student's needs aren't being met by their current plan, you have the right and the responsibility to request a team meeting. You don't need parent permission to request a review. You do need to follow your district's process.

What's Happening With Section 504 in 2026

If you've heard rumors about Section 504 being challenged in court, here's what you need to know.

In September 2024, 17 state attorneys general filed a lawsuit originally called Texas v. Becerra (now Texas v. Kennedy) that challenged updated Section 504 regulations issued by the US Department of Health and Human Services. The original complaint included language asking the court to declare Section 504 unconstitutional, which alarmed disability advocacy organizations and education leaders across the country.

After significant pushback from the disability community, the states filed a clarifying status report in February 2025 stating they had "never moved — and do not plan to move — the Court to declare or enjoin Section 504 of the Rehabilitation Act as unconstitutional on its face." Several states have since withdrawn from the lawsuit entirely.

In January 2026, nine states filed a more narrow amended complaint focused on the integration mandate and specific 2024 regulation changes. The constitutional challenge to Section 504 itself has been dropped. The case is ongoing.

What this means for teachers right now: Section 504 is still in full effect. Every 504 plan currently in place is still legally binding. Schools are still required to evaluate students who may qualify, implement accommodations, and protect students from discrimination based on disability. Nothing about your day-to-day responsibilities has changed.

The case is still worth watching because it could affect how specific Section 504 regulations are applied. For ongoing updates, the Council of Parent Attorneys and Advocates (COPAA) and the Disability Rights Education and Defense Fund publish detailed analysis as the case develops.

Common Mistakes Teachers Make With IEPs and 504 Plans

These are the errors that show up most often in compliance reviews and parent complaints.

Mistake 1: Treating accommodations as optional

Problem: A teacher decides a student doesn't really need extended time on a quiz and skips the accommodation.

This is a federal civil rights violation. Accommodations on an IEP or 504 plan are legally required, not suggestions.

Fix: Implement every accommodation as written. If you think one isn't working or isn't appropriate, request a team meeting to discuss changing it. Never change it on your own.

Mistake 2: Confusing accommodations with modifications

Problem: A teacher gives a student with a 504 plan a shorter, easier assignment when the plan only calls for extended time.

A 504 plan provides accommodations — changes to how a student accesses the curriculum. It does not provide modifications — changes to what the student is expected to learn. Modifications are an IEP-only feature.

Fix: Read the plan carefully. If it says "extended time," give extended time. Don't shorten the assignment unless the plan explicitly says to.

Mistake 3: Not reading the plan

Problem: A teacher discovers in November that one of their students has an IEP and they never received a copy.

This happens more than it should. The case manager is supposed to share plans with all teachers, but caseloads are heavy and things get missed.

Fix: At the start of every year, ask your case manager or 504 coordinator for a list of all your students with plans, and request copies. If you don't get them within a week, escalate.

Mistake 4: Discussing the plan in front of other students

Problem: A teacher tells a student in front of the class that they can have extra time because of their 504 plan.

IEP and 504 information is confidential. Discussing it in front of peers violates FERPA and student privacy rights, and it creates social problems for the student.

Fix: Provide accommodations discreetly. The student knows what they need. The other students don't need to know why.

Mistake 5: Confusing an IEP with a 504 in conversation

Problem: A teacher tells a parent "your son has a 504" when he actually has an IEP, or vice versa.

These are different legal documents with different rights, processes, and protections. Parents catch this and lose trust in the school instantly.

Fix: When in doubt, look it up before the meeting. If you're new to a student, check with the case manager before any parent contact.

Frequently Asked Questions

What is the difference between a 504 and an IEP?

The main difference between a 504 and an IEP comes down to what the plan provides. An IEP provides specialized instruction, related services like speech or occupational therapy, accommodations, and measurable annual goals — it's a complete educational program. A 504 plan only provides accommodations to remove barriers to learning. IEPs are more robust, more legally protected, and require a full multidisciplinary evaluation. 504 plans are simpler, easier to qualify for, and focus on equal access rather than specialized teaching.

What is an IEP or 504 plan?

Both IEPs and 504 plans are formal written documents that schools create to support students with disabilities. The difference is what they provide and how students qualify. An IEP is a legal special education document under IDEA that includes specialized instruction, related services, and measurable goals. A 504 plan is a civil rights document under Section 504 that lists accommodations the student needs to access general education. Both are free and both are legally binding on schools that receive federal funding. The 504 IEP difference is significant in practice — IEPs are roughly 10 times longer and require much more documentation.

Should my student get a 504 plan or IEP?

The answer depends on what kind of support the student actually needs. If the student can learn grade-level content with the right accommodations and supports, a 504 plan is usually the right fit. If the student needs to be taught differently — different curriculum, different pace, modified expectations, or specialized instruction in addition to accommodations — they need an IEP. When in doubt, request a special education evaluation. The school is required to evaluate any student suspected of having a disability, and the evaluation will determine which plan, if either, the student qualifies for. Talking through IEPs and 504s with your case manager or school psychologist is also worth doing before any meeting.

Can a student have both an IEP and a 504 plan?

In most cases, no. If a student has an IEP, they're already protected under Section 504 — every IEP student is automatically covered by 504, and the IEP includes everything a 504 plan would. There's no need for a separate document. However, in rare cases — most often for students with traumatic brain injury, developmental delay, or other health impairments — a student may have both plans active at the same time. If you're unsure, ask your case manager or 504 coordinator. The answer depends on your specific district's practice.

Can a student move from a 504 plan to an IEP?

Yes. If a student on a 504 plan stops making adequate progress or develops more complex needs, the school or parent can request a special education evaluation. This happens often when accommodations stop being enough and the student needs specialized instruction to keep up with grade-level standards.

Who pays for IEP services?

IEP services are funded through a combination of federal IDEA grants, state special education funding, and local district budgets. Schools receive specific federal money to support IEP students. 504 plans receive no federal funding — districts are required to provide accommodations as a civil rights obligation, but no money comes with that requirement.

Does an IEP follow a student to college?

No. IEPs end when a student graduates from high school or ages out at 22. In college, students with disabilities are protected under Section 504 and the Americans with Disabilities Act, but they have to self-identify, request accommodations from the disability services office, and provide their own documentation. Many families are caught off guard by this transition. If you teach high school, helping students understand this shift is part of transition planning.

What happens if a school doesn't follow an IEP or 504 plan?

Parents have the right to file a complaint. For IEPs, parents can request mediation, file a state complaint, or request a due process hearing under IDEA. For 504 plans, parents can file a complaint with the US Department of Education's Office for Civil Rights. Schools that fail to implement plans can face corrective action, compensatory services, and in serious cases, federal funding consequences.
