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

An IEP changes what your child is taught. A 504 plan changes how your child reaches the same teaching. The goals, the timelines and your dispute rights follow from that one difference.

IDEA and Section 504 are federal laws and read the same in every state. What varies is the state's own IDEA evaluation timeline and the district's written Section 504 procedures. Check your school's procedural safeguards notice for both.

Quick answer

An IEP is special education. A 504 plan is access to regular education. An IEP gives your child different teaching, written goals and progress reports. A 504 plan gives your child accommodations so the regular program is reachable. Most children get one or the other.

The two come from different laws. An IEP comes from the Individuals with Disabilities Education Act (IDEA). A 504 plan comes from Section 504 of the Rehabilitation Act of 1973, a civil rights law that reaches every district taking federal money. IDEA is harder to qualify for, and it guarantees far more.

IEP and 504 plan, side by side

Six rows cover almost every practical difference, IDEA first in each one.

IEP and 504 plan, side by side
	IEP, under IDEA	504 plan, under Section 504
Who qualifies	IDEA needs one of 13 named disability categories plus specially designed instruction, at 34 C.F.R. § 300.8.	Section 504 needs only an impairment that substantially limits a major life activity.
Written goals	An IEP carries measurable annual goals and periodic progress reports, at 34 C.F.R. § 300.320.	Section 504 requires neither.
Who writes it	IDEA names the seats at the table, including you, both kinds of teacher, and someone who can read the evaluation.	A 504 group has none.
Evaluation clock	IDEA gives the district 60 days from your written consent, or the state's own timeframe.	Section 504 sets no federal deadline.
Review	An IEP is reviewed yearly and the child reevaluated every three years.	Section 504 requires periodic reevaluation and names no interval.
If you disagree	IDEA gives you prior written notice of a refusal and a due process hearing.	Section 504 gives you notice, a records review and a hearing.

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

No. A student with an IEP is still protected by Section 504, and the district does not write a second plan. The Office for Civil Rights says IDEA-eligible students who have an IEP "are not required to also have a Section 504 plan," because "the IEP developed and implemented in accordance with the IDEA is sufficient."

An IEP already covers everything a 504 plan would. Accommodations go on the IEP.

Which offers more comprehensive services: IEP or 504?

The IEP, and clearly so for a learning disability. Specific learning disability is one of IDEA's 13 categories, at 34 C.F.R. § 300.8(c)(10). A child who needs reading taught a different way needs specially designed instruction, which means adapting the content, methodology or delivery of instruction, at 34 C.F.R. § 300.39(b)(3). A 504 plan cannot do it, so it changes the conditions around the teaching instead. Extra time, a quiet room, a copy of the notes.

The 504 plan wins on one thing. It is quicker, and for a child who can learn from the regular program once the barrier is gone, an IEP only adds paperwork.

Is a 504 plan or an IEP better for ADHD or anxiety?

Neither. The need decides it, not the diagnosis.

ADHD. Usually a 504 plan. ADHD also qualifies under IDEA as other health impairment, at 34 C.F.R. § 300.8(c)(9), when the child needs specially designed instruction.
Anxiety. Usually a 504 plan. The IDEA route runs through emotional disturbance, at 34 C.F.R. § 300.8(c)(4), which requires the condition to have run over a long period of time and to a marked degree.

Questions to ask when comparing IEP and 504

Does my child need specially designed instruction, or only accommodations and access supports?
What evaluation data supports the plan the school is recommending?
If the school offers a 504 plan, what happens if my child needs direct teaching of reading, behavior, or social skills?

Simple parent script

When offered 504 instead of IEP

The team is recommending a 504 plan, but I believe my child needs special education. Please explain the evaluation results showing my child does not need specially designed instruction. If the district refuses an IEP evaluation, please provide prior written notice.

When you want both considered

My child has a disability affecting school. Please evaluate under IDEA and Section 504 and explain which plan, if any, meets my child's need for instruction, accommodations, and related services.

Common mistakes to avoid

Accepting a 504 plan as equal to an IEP when the child needs direct special education instruction.
Assuming good grades mean a child does not need an IEP or 504 support.
Not asking what evaluation was done before the school chose 504 over IDEA.
Treating a 504 plan as a step you pass through before an IEP.

When to get more help

Consider getting help when the school refuses to evaluate under IDEA and offers only 504, the 504 plan is not being followed, the child needs services that only an IEP typically provides, or you need to challenge eligibility under either law.

An advocate reads the evaluation against the plan the district proposes and sits next to you while the group decides. They are not attorneys. They cannot represent you at a due process hearing. Most charge $75 to $150 per hour, and you can see who works in your state.
