IEP vs 504 Plan, and Private School Rights
Two different laws, two different plans
An autistic child in a public school may get help under one of two federal laws. They are not the same.
| IEP (under IDEA) | 504 Plan (under Section 504) | |
|---|---|---|
| Law | Individuals with Disabilities Education Act | Section 504 of the Rehabilitation Act of 1973 (a civil rights law) |
| What it provides | Specially designed instruction plus related services, with measurable goals | Accommodations and access so the child can learn alongside peers |
| Who qualifies | Child has one of IDEA's disability categories and needs special education | Child has a physical or mental impairment that substantially limits a major life activity |
| Eligibility scope | Narrower. Must need special education. | Broader. Many children who do not qualify for an IEP still qualify for 504. |
| Extra federal funding | Yes, the school gets IDEA funds | No dedicated funding attached |
| Example supports | Reading goals, speech therapy, ABA-style behavior supports, a resource room | Extended time, sensory breaks, preferential seating, a quiet testing room |
How eligibility differs (why this matters)
Section 504 uses a broad definition (source: US Department of Education, Office for Civil Rights). A child qualifies if they have "a physical or mental impairment that substantially limits one or more major life activities." Major life activities include learning, concentrating, thinking, communicating, reading, and caring for oneself, among others. Autism can substantially limit several of these.
IDEA is narrower. A child must both have a covered disability and need special education because of it. A bright autistic child who keeps grades up but needs accommodations for sensory and social needs may not qualify for an IEP but often does qualify for a 504 plan.
Rule of thumb
- Needs actual specialized teaching or therapy built into the school day: aim for an IEP.
- Needs accommodations to access a regular classroom but not specialized instruction: a 504 plan may fit.
- An IEP generally carries stronger procedural protections and progress monitoring than a 504 plan. If a child qualifies for both, families usually prefer the IEP.

Children placed by parents in private school
If parents choose to enroll their child in a private school, the child's IDEA rights change in a big way (source: IDEA regulations, summarized by the Texas Education Agency guide citing the federal OSEP guidance):
- The child loses the individual entitlement to a free appropriate public education (FAPE) that a public-school child has. The public district does not have to write a full IEP or deliver everything the child needs.
- The school district where the private school is located is still responsible for Child Find, meaning it must locate and evaluate parentally placed private-school children who may have disabilities, including homeschooled children.
- Instead of an IEP, an eligible private-school child may get a "services plan." These are called equitable services, and they are funded from a proportionate share of the district's federal IDEA Part B money.
- Because only a limited pool of money is set aside, not every eligible private-school child gets services. The district decides which children get equitable services through a consultation process. A child could be found eligible and still receive little or nothing.
The separate tuition-reimbursement path
There is a different situation, often confused with the above. If a parent believes the public school failed to provide FAPE and then moves the child to a private school to get appropriate services, the parent may be able to seek tuition reimbursement from the district through a due process hearing. That is a distinct legal claim from the "parentally placed" equitable-services rules, and it usually requires giving the district proper notice first. This path is fact-specific. Families pursuing it should talk to a special education advocate or attorney.
What to do
- Ask the school to evaluate under IDEA first (the higher level of protection). If the child does not qualify for an IEP, ask about a 504 plan in the same breath.
- If your child is in private school, contact the public district where the private school sits and ask about Child Find and equitable services. Do not assume the private school will do this.
- Keep everything in writing and keep copies.
