Quick answer
An IEP is a plan under IDEA that provides specially designed instruction and related services to students whose disability affects their education. A 504 plan, under Section 504 of the Rehabilitation Act, provides accommodations so a student with a disability has equal access to learning. In short: an IEP changes what or how a student is taught; a 504 plan changes how the student accesses the same instruction.
Key takeaways
- IEPs come from IDEA (an education law); 504 plans come from Section 504 (a civil rights law).
- IEPs provide specially designed instruction; 504 plans mainly provide accommodations.
- Section 504 uses a broader definition of disability, so more students qualify.
- Both are free to families and both are legally enforceable.
Parents and teachers often hear "IEP" and "504" in the same conversation. Both help students with disabilities succeed in school, but they're built on different laws, cover different groups of students, and offer different types of support.
The short version
IEP
Law: IDEA (education law)
Specially designed instruction plus related services and accommodations, written as a detailed plan with measurable goals.
504 plan
Law: Section 504 (civil rights law)
Accommodations and supports that remove barriers so the student can access the same instruction as classmates.
Different laws, different purposes
The Individuals with Disabilities Education Act (IDEA) is a special education law. It requires public schools to provide eligible students with a free appropriate public education designed around their individual needs.
Section 504 of the Rehabilitation Act of 1973 is a civil rights law. It prohibits discrimination on the basis of disability in any program that receives federal funding — including public schools. A 504 plan is the school's way of making sure a student's disability doesn't block their access to learning.
Who qualifies
For an IEP, a student must have a disability in one of IDEA's categories and need specially designed instruction because of it. For a 504 plan, a student must have a physical or mental impairment that substantially limits one or more major life activities — such as learning, reading, concentrating, breathing, or walking.
What each one provides
Common 504 accommodations
- Extended time on tests and assignments
- Preferential seating
- Breaks during class or testing
- Access to a nurse for medication or health monitoring
- Audiobooks, text-to-speech, or large print
- A copy of class notes
What an IEP can add
- Specially designed instruction from a special education teacher
- Related services, such as speech-language therapy, OT, PT, or counseling
- Measurable annual goals with regular progress reports
- Modifications to what the student is expected to learn
- Placement in a resource room or specialized program when appropriate
How the process differs
- Evaluation: both require an evaluation, but IDEA's evaluation rules are more detailed.
- Written plan: IDEA requires a written IEP with specific required parts; Section 504 doesn't require a specific format, though most schools write a 504 plan.
- Team: an IEP team has required members, including the parents; a 504 team is made up of people who know the student and the evaluation data.
- Review: IEPs are reviewed at least yearly; 504 plans are reviewed periodically, and many schools review them yearly too.
- Parent rights: both come with procedural protections; IDEA's are more detailed, including prior written notice and specific dispute options.
Which one is right for a student?
The question to ask is: does the student need instruction to be taught differently, or do they mainly need barriers removed so they can learn alongside classmates? If they need specially designed instruction or services such as therapy, an IEP is usually the right fit. If accommodations alone allow them to succeed, a 504 plan may be enough.
Who carries out these plans
504 plans are mostly carried out by classroom teachers, with support from counselors and school nurses. IEPs bring in special education teachers, paraprofessionals, and related-service providers such as speech-language pathologists, occupational therapists, and school psychologists. Both depend on schools having enough qualified staff in place.
Frequently asked questions
Is a 504 plan or an IEP better?
Neither is better — they serve different needs. An IEP provides specially designed instruction and services; a 504 plan provides accommodations for equal access. The right one depends on what the student needs to succeed.
Can a student have both an IEP and a 504 plan?
Generally no. A student with an IEP is already protected under Section 504, and their accommodations are written into the IEP, so a separate 504 plan isn't needed.
Does ADHD qualify for an IEP or a 504 plan?
It can qualify for either. A student with ADHD may get an IEP under the "other health impairment" category if they need specially designed instruction, or a 504 plan if accommodations are enough.
Do 504 plans apply in college?
Section 504 and the Americans with Disabilities Act apply in college, but IEPs don't. College students request accommodations through the school's disability services office.
