504 Plan vs IEP: What's the Difference and Which Does Your Child Need?

Someone at the school mentioned a 504 Plan. Someone else mentioned an IEP. They've used both terms and you're not sure which one your child needs, what the difference is, or whether you should be asking for something specific.

Here's the clear explanation.

What They Have in Common

Both 504 Plans and IEPs are legal documents that entitle children with disabilities to specific accommodations or services in US public schools. Both are free to families. Both involve the school and parents working together. And both require the child to have a qualifying disability.

That's where the similarities end.

What a 504 Plan Is

A 504 Plan is a civil rights document under Section 504 of the Rehabilitation Act of 1973. It prohibits discrimination against students with disabilities and requires that schools provide accommodations that allow a student to access education on an equal basis with their peers.

504 Plans are accommodations, not services. They change the environment around the child — extra time on tests, preferential seating, written instructions, noise-cancelling headphones, a quiet room for tests — but they don't provide additional instruction, therapeutic services, or a specially designed curriculum.

Eligibility: any child with a physical or mental impairment that substantially limits a major life activity. ADHD frequently qualifies. The threshold is lower than for an IEP.

What an IEP Is

An Individualized Education Program is a more comprehensive document under IDEA (Individuals with Disabilities Education Act). It provides for specially designed instruction — meaning the curriculum, teaching methods, and evaluation can all be modified specifically for the child.

IEPs also fund related services — speech therapy, occupational therapy, psychological counseling, physical therapy — that the school provides at no cost to the family.

Eligibility: the child must have one of 13 specific disability categories recognised by IDEA, and the disability must adversely affect their educational performance. ADHD can qualify under Other Health Impairment (OHI) or, if accompanied by a specific learning disability, under that category.

Which Does Your Child Need?

A 504 Plan may be sufficient if: your child's primary need is accommodations (more time, different seating, flexible submissions) and their academic performance is generally at grade level without additional instruction.

An IEP is likely needed if: your child is performing significantly below grade level, needs specialist instruction (reading intervention, language therapy), requires related services (OT, speech), or needs a fundamentally different approach to learning rather than just environmental changes.

The important point: if your child needs an IEP and only has a 504, they're underserved. Don't accept a 504 because it's easier for the school if your child's needs are IEP-level.

How to Request Either

Request in writing to the school principal and the Director of Special Education. For an IEP evaluation, use the words "I am requesting a special education evaluation under IDEA" — this triggers a legal response requirement. For a 504, write to the school's 504 coordinator.
