IEP vs 504: Key Differences, How Teams Decide and Examples

Estimated reading time: 15 minutes

IEP vs 504 is the comparison between the two plans public schools use for students with disabilities: an individualized education program (IEP) under the Individuals with Disabilities Education Act (IDEA), for a student in one of 13 disability categories who needs special education (34 CFR 300.8, 300.320), and a 504 plan under Section 504 of the Rehabilitation Act, for a student whose impairment substantially limits a major life activity (34 CFR 104.3(j), 104.33). In short, an IEP delivers specially designed instruction with measurable goals, while a 504 plan most often provides the accommodations, aids and services a student needs to access the general education program. This guide compares the two in one table, explains how teams decide, works through ADHD, dyslexia, anxiety, diabetes and exit cases, and covers moving between plans. It is not legal advice.

Executive Summary

In the 2023-24 school year, about 7.6 million public school students in preschool through grade 12 were served under IDEA, 15% of enrollment, and about 1.9 million more, 4%, were served only under Section 504, according to the Civil Rights Data Collection report of the Department of Education’s Office for Civil Rights (OCR), September 2026. Every student with an IEP is also protected by Section 504, but not every student covered by Section 504 is eligible for special education.

Families often ask which plan is better. In law, an evaluation decides which plan applies, and the student’s needs decide what it contains.

IEP vs 504: Comparison Table

An IEP and a 504 plan differ in the law behind them, who qualifies, what the student receives and the procedures that protect families.

The 504 side is explained in full in our 504 plan guide.

The Key Difference: Instruction or Access

The key difference is that an IEP changes how a student is taught, while a 504 plan usually changes how the student gets to and takes part in what is taught.

IDEA defines specially designed instruction as adapting “the content, methodology, or delivery of instruction” to address the student’s unique needs and ensure access to the general curriculum (34 CFR 300.39(b)(3)). A student in an IDEA category who needs only a related service is not eligible under IDEA, unless state standards treat that service as special education (300.8(a)(2)). Accommodations, by contrast, keep the learning standard the same; see accommodations vs modifications and our specially designed instruction examples.

The line is not absolute: a 504 plan can include special education and related services (104.33(b)(1)), and an IEP can list accommodations as supplementary aids and services.

How Teams Decide Between an IEP and a 504 Plan

Teams do not pick a plan; they evaluate the student, and the eligibility findings decide which plan applies.

1. Suspect and refer. IDEA’s Child Find covers children “in need of special education and related services,” even those advancing from grade to grade (300.111).
2. Evaluate under IDEA first when specially designed instruction may be needed; the steps are in our guide to special education evaluation.
3. Decide IDEA eligibility on both prongs: the category and the need. The IEP is then written at an IEP meeting held within 30 days (300.323(c)).
4. If not eligible under IDEA, consider Section 504. OCR’s ADHD resource guide says an IDEA ineligibility finding “does not relieve the school district of its obligation to evaluate the student, as appropriate, under Section 504.”

IEP or 504 for ADHD

A student with ADHD gets an IEP when ADHD causes a need for specially designed instruction, and a 504 plan when the student needs accommodations or services but not that instruction.

IDEA names attention deficit hyperactivity disorder as an example of a health problem under other health impairment (300.8(c)(9)), and OCR notes that students with ADHD can also qualify under the specific learning disability or emotional disturbance categories. Two original examples to adapt:

• Liam, grade 4: reads and writes on grade level, but loses focus during long tasks and misses directions. The team finds ADHD substantially limits concentrating and writes a 504 plan with movement breaks, chunked assignments and a daily planner check.
• Sofia, grade 7: has the same accommodations, yet still hands in a third of her written work and cannot plan multi-step assignments. An IDEA evaluation finds she needs explicit instruction in planning and self-monitoring; she qualifies under other health impairment and receives an IEP with measurable goals.

A full ADHD plan example is in our 504 plan guide.

Case Examples: Dyslexia, Anxiety, Diabetes and Exit From Special Education

The same diagnosis can lead to an IEP, a 504 plan or neither, depending on what the student needs; these original examples use fictional students.

Dyslexia

Noah, a third grader, cannot yet decode grade-level words and needs structured reading instruction every day: that is specially designed instruction, and IDEA names dyslexia within specific learning disability (300.8(c)(10)), so he receives an IEP. Ana, a ninth grader, reads accurately but slowly after years of intervention; she needs audio texts and extended time, so a 504 plan fits. In Texas, dyslexia instruction itself is delivered through an IEP. Supports by area are in dyslexia accommodations.

Anxiety

Elena, a tenth grader with an anxiety disorder, attends class and keeps her grades with a plan for breaks, advance notice of presentations and a quiet testing room: a 504 plan. If anxiety kept a student out of school for weeks and fears tied to school problems adversely affected performance “over a long period of time and to a marked degree,” the team would evaluate under IDEA’s emotional disturbance category (300.8(c)(4)).

Diabetes

Ava, a third grader with type 1 diabetes, needs blood glucose checks, snacks, trained staff on field trips and make-up time after appointments. Diabetes is listed under other health impairment (300.8(c)(9)), but Ava needs no specially designed instruction, so she has a 504 plan with her health plan attached.

A Student Exited From Special Education

Marcus, a tenth grader, received speech-language services under an IEP. His reevaluation shows he no longer needs special education; IDEA requires that evaluation before ending eligibility (300.305(e)(1)) and prior written notice of the change (300.503). The team then asks whether a remaining impairment substantially limits a major life activity: if so, he may receive a 504 plan; a past disability alone, a “record of” one, does not trigger Section 504 FAPE, according to OCR.

Moving Between an IEP and a 504 Plan

A student moves between an IEP and a 504 plan only through an evaluation and written notice, never by an informal decision at a single meeting.

• From a 504 plan to an IEP: a parent or the district may request an initial IDEA evaluation (300.301(b)); after written consent it is completed within 60 days or the state’s timeline. Flat progress despite accommodations is a reason to consider a referral. Keeping the 504 plan in place until an IEP is in effect avoids a gap.
• From an IEP to a 504 plan: the district evaluates before finding a student no longer eligible, except at graduation with a regular diploma or at the age limit (300.305(e)), gives prior written notice, and then makes a Section 504 decision based on evaluation (104.35).
• When a parent revokes consent for special education in writing, the district must stop IEP services after prior written notice and may not use due process to continue them (300.300(b)(4)). Ask district counsel how Section 504 applies in that situation.
• Both plans at once: OCR states that a student eligible under IDEA “must have an IEP,” and implementing it is one way to meet Section 504. TEA advises addressing any additional Section 504 needs within the IEP.

Common Misconceptions About IEPs and 504 Plans

Most confusion about IEPs and 504 plans comes from a few beliefs that federal rules do not support.

• “A 504 plan is a weaker IEP.” It comes from a different law with a different purpose, and it can include services.
• “Parents choose the plan.” Evaluations decide eligibility; parents consent to evaluations (and, under IDEA, to services) and take part in decisions.
• “A diagnosis decides.” Under IDEA, a need for special education is required; under Section 504, a diagnosis is not enough on its own.
• “Good grades rule out both.” IDEA covers a child who needs special education “even though the child has not failed or been retained in a course or grade” (300.101(c)), and OCR warns that grades can hide a substantial limitation.
• “504 plans have no rights attached.” Section 504 requires notice, records access, an impartial hearing and a review procedure.

What Families and Staff Can Ask the Team

These questions help a family or a teacher understand an IEP vs 504 decision at the meeting:

• Which evaluation data show whether the student needs specially designed instruction?
• Which major life activities are substantially limited, judged without medication or other supports?
• What will change in how the student is taught, and what only in how the student takes part?
• How will we know in three months whether the plan is working?
• What would lead the team to reevaluate under IDEA?

Funding and Staffing

IDEA comes with federal Part B grants ($14.23 billion for grants to states in FY2026, as our IDEA guide explains), while Section 504 and the ADA “do not provide any type of funding,” according to OCR. Districts fund 504 plans themselves and may use any public or private source (104.33(c)(1)). Staffing is the tighter limit: 45 states reported special education teacher shortages in 2024-25 (Learning Policy Institute, 2026).

Common Mistakes District Leaders Make

1. Offering a 504 plan instead of an IDEA evaluation when specially designed instruction may be needed.
2. Closing the file after an IDEA “not eligible.” Section 504 still has to be considered.
3. Writing a 504 plan for a student with an IEP instead of adding the needs to the IEP.
4. Exiting students without an evaluation or prior written notice.
5. Applying IDEA discipline rules only. Students with 504 plans also need an evaluation before long removals.
6. Letting campuses use different referral routes for the same needs.

Questions District Leaders Should Ask

• What share of our students have a 504 plan compared with an IEP, by campus?
• How many students with 504 plans were referred for an IDEA evaluation last year, and how many qualified?
• How many IDEA exits were followed by a Section 504 decision?
• Do campuses handle discipline for 504 students the same way?

Frequently Asked Questions

What is the difference between an IEP and a 504 plan?

An IEP is required by IDEA for a student in one of 13 disability categories who needs special education, and it sets measurable annual goals and specially designed instruction. A 504 plan is written under Section 504, a civil rights law, for a student whose impairment substantially limits a major life activity, and it usually lists accommodations and services that give access to general education.

Is a 504 plan the same as an IEP?

No. They come from different laws, cover different groups of students and follow different procedures. An IEP must include present levels, measurable goals and progress reporting (34 CFR 300.320); Section 504 regulations do not require any written plan, although districts usually write one. A student eligible under IDEA must have an IEP, which also meets Section 504.

Is a 504 plan special education?

Not in the IDEA sense. A 504 plan comes from a civil rights law, and its default setting is the regular classroom (104.34(a)). Section 504 FAPE can still include special education and related services (34 CFR 104.33(b)(1)). A student who needs specially designed instruction because of a disability in an IDEA category should be evaluated for an IEP.

Should a student with ADHD have a 504 plan or an IEP?

It depends on need, not on the diagnosis. A student whose ADHD calls for accommodations such as breaks, chunked work and extra time may be served with a 504 plan. A student who needs specially designed instruction, for example in planning or self-monitoring, may qualify for an IEP under other health impairment, specific learning disability or emotional disturbance.

Does a student with autism get a 504 plan or an IEP?

Autism is one of IDEA’s 13 categories (34 CFR 300.8(c)(1)), so a student with autism who needs specially designed instruction, for example in social communication, qualifies for an IEP. A student with autism who needs only accommodations, such as a predictable schedule or a quiet space, may be served with a 504 plan after a Section 504 evaluation.

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

Usually not. OCR states that a student eligible under IDEA “must have an IEP,” and implementing that IEP is one way to meet Section 504. TEA, for example, advises writing needs linked to another condition into the IEP. The student keeps Section 504’s protections against discrimination in every school program.

Which is better, an IEP or a 504 plan?

Neither is better in general; each fits a different need. An IEP offers specially designed instruction, measurable goals and IDEA’s detailed procedures. A 504 plan offers access through accommodations and services for a broader group of students. The right plan is the one the evaluation supports and that addresses the student’s documented needs.

Conclusion

IEP vs 504 is less a choice than a finding. When a disability calls for specially designed instruction, IDEA and an IEP apply; when a student needs access through accommodations, aids or services, Section 504 and a 504 plan apply. Districts that evaluate first and consider both laws at every decision keep the comparison where it belongs: on the student’s needs.
