You've noticed your child is struggling at school. Maybe they're bright but can't finish tests on time. Maybe they hold it together all day and fall apart the moment they get home. You've heard "504 plan" and "IEP" mentioned by teachers, other parents, and pediatricians — but nobody has actually explained what either one means for your specific kid.

Here's what you need to know: the differences between the two plans, how to figure out which one fits your child's situation, and how to get the process moving in 2026.

The Core Difference: Support vs. Specialized Instruction

Both a 504 plan and an IEP are legal documents that protect your child's right to access education. But they come from different laws and do very different things.

A 504 plan comes from Section 504 of the Rehabilitation Act of 1973. Its job is to remove barriers so your child can access the same education as their peers. Think accommodations: extra time on tests, preferential seating, a quiet testing room, access to a fidget tool. The school doesn't change what it teaches or how it measures success — it just levels the playing field.

An IEP (Individualized Education Program) comes from the Individuals with Disabilities Education Act (IDEA) and goes further. An IEP means your child receives specially designed instruction, which can include modified curriculum, direct services from a special education teacher, speech therapy, occupational therapy, social skills support, and more. Progress is measured against goals written specifically for your child.

The short version: a 504 adjusts how your child accesses learning. An IEP changes what and how your child is taught.

Who Qualifies for Each

504 Plan Eligibility

To qualify for a 504, your child needs a documented physical or mental impairment that substantially limits one or more major life activities — learning, concentrating, reading, communicating, and caring for oneself all count.

ADHD, Autism, anxiety, dyslexia, and many other neurodivergent profiles can qualify. The bar is lower than for an IEP. You don't have to prove the condition is affecting academic performance specifically, just that it limits a major life activity.

IEP Eligibility

To qualify for an IEP, your child must meet two conditions:

1. They have a disability that falls into one of 13 specific categories defined by IDEA (ADHD falls under "Other Health Impairment"; Autism has its own category)
2. That disability must be shown to adversely affect educational performance

Both conditions have to be true. A child can have an ADHD diagnosis and still not qualify for an IEP if the school determines it isn't meaningfully impacting their learning. This is where a lot of parents hit a wall — and it's a frustrating one.

Side-by-Side Comparison

When a 504 Is the Right Fit

A 504 plan often works well when your child:

• Has a diagnosis (ADHD, anxiety, Autism, dyslexia, etc.) but is keeping up academically
• Mainly needs accommodations to access the same material as peers
• Is in general education classes and performing at or near grade level
• Needs supports like extended time, movement breaks, or reduced homework volume

Many kids with ADHD who are high-masking or academically strong will qualify for a 504 but not an IEP. That doesn't mean their needs aren't real. It means the accommodations route may be enough right now — and it can always be revisited as things change.

When an IEP Is the Right Fit

An IEP is worth pursuing when your child:

• Is significantly behind grade level in one or more areas
• Needs direct services like speech therapy, occupational therapy, or social skills instruction
• Requires a modified curriculum, not just extra time
• Has an Autism diagnosis with support needs that go beyond classroom accommodations
• Is in or needs a specialized classroom setting

For many autistic children — and especially those with AuDHD (co-occurring ADHD and Autism) — an IEP provides a depth of support that a 504 simply can't match. Services are written into the document and are legally required to be delivered.

Can a Child Have Both?

Not at the same time. A child with an IEP is already protected under IDEA, which is the stronger law, and the IEP covers everything a 504 would. If your child later transitions out of special education services, they may move to a 504 to keep their accommodations in place.

How to Get the Process Started in 2026

Step 1: Request an Evaluation in Writing

You have the right to request a special education evaluation from your school district at any time. Send a written request to the principal and special education coordinator, and keep a copy. The school has a legal deadline to respond — typically 60 days, depending on your state.

You can also request a 504 evaluation separately if you're not pursuing an IEP.

Step 2: Get an Independent Evaluation

Schools conduct their own evaluations, but they're not always comprehensive. A school psychologist's assessment is often shorter and narrower than a full neuropsychological evaluation completed by a licensed psychologist.

If you want a thorough picture of your child's cognitive profile — processing strengths and challenges, attention, executive function, social communication — an independent evaluation gives you that. It also gives you documentation that carries real weight in IEP and 504 meetings.

This is where a telehealth evaluation can make a meaningful difference. Sachs Center conducts comprehensive neuropsychological evaluations for children via telehealth, available across 48 or more states. There's no 18-month in-person waitlist. The evaluation is done from home, by licensed psychologists who understand how ADHD and Autism present in children who have been missed or misread by earlier assessments.

Step 3: Attend the Eligibility Meeting

After the evaluation, the school holds a meeting to determine eligibility. Bring your independent evaluation report if you have one. You are a full member of this team — not a guest. You can ask questions, push back on findings, and request that specific supports be included.

Step 4: Develop the Plan

If your child qualifies for an IEP, the team writes it together. Goals are set, services are identified, and placement is determined. If they qualify for a 504, accommodations are listed and agreed upon.

Ask for everything in writing. Ask how progress will be measured. Ask who is responsible for each service.

Step 5: Review and Advocate

IEPs are reviewed annually. 504 plans vary by district but should be revisited at least once a year. You can request a meeting at any time if something isn't working.

What Happens If the School Says No

Schools deny evaluations and eligibility more often than they should. If the school refuses to evaluate your child, they must give you written notice explaining why. From there, you have the right to:

• Request an Independent Educational Evaluation (IEE) at the school's expense
• File a complaint with your state's department of education
• Request mediation or a due process hearing

Having a comprehensive independent evaluation already in hand strengthens your position significantly before any of those steps become necessary.

A Note on Diagnosis

Neither a 504 plan nor an IEP requires a formal outside diagnosis. Schools can find a child eligible based on their own evaluation process. But a formal diagnosis from a licensed psychologist — especially a comprehensive one that explains the full cognitive and behavioral profile — gives you clearer answers and stronger documentation.

It also gives your child something the school process rarely provides: a real understanding of how their brain works. That matters well beyond the paperwork.

FAQs

Q: Does my child need a formal diagnosis to get a 504 or IEP?
A: Not necessarily. Schools can determine eligibility through their own evaluation. That said, a formal diagnosis from a licensed psychologist — especially a comprehensive neuropsychological evaluation — provides stronger documentation and a fuller picture of your child's needs.

Q: What's the difference between a 504 plan and an IEP in plain terms?
A: A 504 plan provides accommodations so your child can access the same education as their peers. An IEP provides specialized instruction and services tailored specifically to your child. A 504 adjusts how your child learns; an IEP changes what and how they're taught.

Q: My child has ADHD. Which plan do they need?
A: It depends on how ADHD is affecting their education. If they're keeping up academically but need supports like extended time or preferential seating, a 504 may be enough. If ADHD is significantly impacting their performance and they need specialized instruction or services, an IEP may be the better fit.

Q: Can I request an evaluation from the school at any time?
A: Yes. You have the legal right to request a special education evaluation in writing at any time. The school must respond within the timeframe set by your state, typically around 60 days.

Q: What if I disagree with the school's evaluation results?
A: You have the right to request an Independent Educational Evaluation (IEE), and in some cases the school is required to pay for it. Having an independent neuropsychological evaluation completed beforehand can also help you advocate more effectively during eligibility meetings.

Q: Does an IEP follow my child to college?
A: No. IDEA doesn't apply to colleges and universities. However, a 504 does carry forward in a modified form — students can request accommodations through their college's disability services office, typically using documentation from a recent evaluation.

Q: My child has both ADHD and Autism. Does that change anything?
A: It can, yes. Children with co-occurring ADHD and Autism — sometimes called AuDHD — often have more complex support needs that a 504 alone may not fully address. A comprehensive evaluation that looks at both profiles together gives the IEP team a much clearer picture of what your child actually needs.

Where to Go From Here

Figuring out the right plan for your child is hard enough without also navigating long waitlists just to get an evaluation. If you're looking for a comprehensive, licensed assessment you can complete from home, Sachs Center offers virtual neuropsychological evaluations for children across 48 or more states. The evaluation covers ADHD, Autism, AuDHD, and full cognitive and academic profiles — giving you the documentation you need to advocate effectively when you walk into that school meeting.

You already know your child. Getting the right paperwork behind you just means the school has to listen.
