504 Plan vs. IEP in Texas: Which One Does Your Child Actually Need?

The school has suggested a 504 plan. You have heard about IEPs. You are not sure which one offers stronger protection — and you suspect the school may be steering you toward whichever is easier to manage on their end. In Texas, the 504 vs. IEP question has layers that most national resources never address, particularly around dyslexia and ADHD.

The Core Legal Difference

An IEP is created under IDEA (federal special education law) and Texas's implementing rules in TAC Chapter 89. It provides specially designed instruction — meaning the actual teaching content, methodology, or delivery is specifically adapted to your child's disability. An IEP comes with a mandatory ARD committee, strict evaluation timelines, specific procedural safeguards, and the right to dispute resolution through TEA.

A 504 plan is created under Section 504 of the Rehabilitation Act, which prohibits disability discrimination by any program receiving federal funding. It provides accommodations and modifications within general education — extended time, preferential seating, reduced homework load, assistive technology — but does not change the instructional content itself.

The standards for dispute are different too. IEP disagreements can go to a TEA complaint, mediation, or due process hearing with a neutral hearing officer. A 504 dispute goes through the district's own 504 coordinator and then to the U.S. Department of Education's Office for Civil Rights (OCR) — a slower, less parent-friendly path.

Who Qualifies for Each

IEP eligibility requires two things: (1) your child meets one of Texas's 13 disability categories under TAC §89.1040, and (2) the disability adversely affects their educational performance to the degree that they need specially designed instruction.

504 eligibility has a lower threshold: your child has a physical or mental impairment that substantially limits a major life activity (including learning, reading, concentrating, thinking, communicating). A child who does not qualify for an IEP can often qualify for 504.

This creates a spectrum that Texas parents frequently misunderstand: a child with mild ADHD who needs extended time but is passing all classes with that support might do fine on a 504. A child with ADHD who needs a modified curriculum, direct instruction in organizational skills, or a behavior intervention plan almost always needs an IEP.

The Dyslexia Exception in Texas: HB 3928

Texas changed the landscape for dyslexia significantly with House Bill 3928, which took effect in 2022. Before HB 3928, many Texas students with dyslexia were served only under the separate state Dyslexia Program — often with a 504 plan — without the IEP protections that IDEA provides.

HB 3928 requires Texas school districts to evaluate students who are suspected of having dyslexia for Specific Learning Disability (SLD) under IDEA, not just for the Dyslexia Program. This means:

• If your child has dyslexia and it is adversely affecting their educational performance, the school must consider an IEP — not just a 504 or Dyslexia Program placement
• The evaluation must be a full FIIE, not a limited dyslexia screener
• If found eligible for SLD, your child is entitled to all IEP protections

Texas now has 212,167 students identified with SLD of dyslexia. If your child is being served only under a 504 or Dyslexia Program and is still struggling significantly, it is worth requesting a FIIE to assess for SLD eligibility.

ADHD: When to Push for an IEP vs. a 504

ADHD is where the 504 vs. IEP question comes up most often in Texas ARD meetings. Here is the framework:

504 may be appropriate if:

• Your child has diagnosed ADHD but is performing at or near grade level with accommodations
• The main challenges are attention management, organization, and test-taking
• The school's response to the 504 accommodations is showing genuine progress

IEP under OHI (Other Health Impairment) may be more appropriate if:

• ADHD is causing significant academic delays despite accommodations
• Your child needs direct instruction in executive function, study skills, or behavior management
• A Behavior Intervention Plan (BIP) is warranted
• The school is providing minimal or no response-to-intervention data showing the 504 is working

Under Texas law, OHI — the category that captures most ADHD diagnoses — requires showing that the condition "results in limited alertness with respect to the educational environment, that adversely affects the child's educational performance." If ADHD is clearly affecting academic performance, the district cannot default to a 504 on the grounds that it is administratively simpler.

What the 504 Does Not Provide

Texas parents choosing between the two should understand what a 504 explicitly does not give you:

• No ARD committee. The 504 team is not governed by the strict membership requirements of an ARD. Whoever the district puts in that room is generally up to the district.
• No evaluation timeline. There is no state-mandated window within which a 504 evaluation must be completed.
• No IEE right. You cannot demand an independent evaluation at public expense if you disagree with the 504 evaluation.
• No stay-put rights. If the district wants to change or remove the 504, there is no automatic right to keep the previous plan in place while you dispute it.
• No dedicated STAAR accommodations framework. IEP STAAR accommodations are governed by TEA's Accommodations for Students with Disabilities guidelines. 504 STAAR accommodations exist, but they require separate documentation and are sometimes disputed by testing administrators who are not familiar with 504 accommodations as distinct from IEP ones.

When the School Pushes 504 Over IEP

Texas districts sometimes default to 504 because it requires fewer staff resources and creates less legal accountability than an IEP. If the school is recommending a 504 and you believe your child needs an IEP, you have the right to:

1. Request a full FIIE in writing, citing TAC §89.1011 and the Child Find obligation under TAC §89.1001
2. Ask specifically why the team believes your child does not need specially designed instruction
3. Request that the rationale for the 504 recommendation (rather than IEP) be included in the Prior Written Notice (PWN)

The PWN is your record. If the district decides not to evaluate for IEP eligibility, they must provide you a PWN explaining why. That document can support a TEA complaint if you believe the decision was wrong.

Making the Decision

A 504 plan is appropriate when accommodations alone are sufficient. An IEP is appropriate when your child needs modified instruction — in content, method, or delivery — to make progress. If you are uncertain which applies, the question to ask the ARD or 504 team is: "What evidence shows that accommodations alone, without specially designed instruction, are sufficient for this child to make appropriate academic progress?"

If they cannot answer that with data, the IEP discussion is not over.

The Texas IEP & 504 Blueprint covers both the IEP and 504 pathways in detail, with step-by-step guidance for requesting evaluations, preparing for ARD meetings, and responding when the district recommends the wrong plan for your child's needs.
