Autism Evaluation in Pennsylvania

The three routes, and why the free ones come first

Families often assume the only way in is a private specialist with a twelve-month waitlist. Two of the three routes are free, and both of them run on a federal deadline that the agency does not get to ignore.

• Early intervention, birth to 3. A state-run program. You refer your own child — no diagnosis and no doctor’s note required — and the evaluation is free regardless of income.
• Your school district, age 3 and up. Also free, also something you can start yourself, and the district has an affirmative legal duty to find and evaluate children who may have a disability even before they enroll.
• A private evaluation. What most people picture. It produces the medical diagnosis insurers and Medicaid usually want, and it is the one with the waitlist.

The practical advice is to start the free route today and get on private waitlists at the same time. Nothing about doing one prevents the other, and a school evaluation and a medical diagnosis are different documents that get used for different things — educational eligibility on one side, insurance authorization on the other. Plenty of families need both.

If your child is under 3 in Pennsylvania

Part C of IDEA is administered here by Bureau of Early Intervention Services and Family Supports, Office of Child Development and Early Learning, Departments of Education and Human Services (program information).

The number to call: (800) 692-7288. You can refer your own child. You do not need a diagnosis, a referral, or a reason beyond a concern about how your child is developing.

Then a clock starts. Once the program receives the referral, federal law gives it 45 days to complete the evaluation, complete the assessment, and hold the meeting that writes your child’s first plan. Not 45 days to call you back — 45 days for all of it. Note the date you referred and keep it.

Early intervention is also the one part of this system with no waitlist by design, because the deadline is the entitlement. If you are told there is a wait, that is worth questioning, and your Parent Training and Information center can help you do it.

One thing to know before the 3rd birthday: early intervention ends there, and the handover to the school district is its own process rather than something automatic. We cover the timing in the under-3 guide.

If your child is 3 or older

Ask your school district for an evaluation, in writing. Email is fine and email is better than a phone call, because the clock starts from a date and you want that date to exist somewhere you can point to.

Two federal rules do the work here. Districts have an affirmative duty to identify and evaluate children who may have a disability — that duty covers children who are not yet enrolled and children in private school, so “they don’t attend here” is not a reason to refuse. And once you consent to an evaluation, the district has 60 days to complete it, unless Pennsylvania has established its own timeline, which some states have. Ask which applies and get the answer in writing.

A school evaluation decides whether your child is eligible for special education. It does not produce a medical diagnosis, and a district saying “we don’t diagnose autism” is accurate rather than evasive. It is also why families often pursue both routes. Requesting a school evaluation has the letter template and what to do when a district says no.

Where to get evaluated in Pennsylvania

38 diagnostic providers across 36 Pennsylvaniacounties. Every one is a named practice with a website that resolves — a large number of listings were removed in August 2026 after they turned out not to describe real businesses, and these are what survived that. We do not rank them, take payment for placement, or claim to have assessed anyone’s clinical work. Confirm licensure and current availability yourself.

Diagnostic providers are listed in 24 more Pennsylvania counties — start from the Pennsylvania page to find yours.

When you call, ask two questions that decide whether the waitlist number means anything: how long until the appointment, and how long after that until you get the written report. The second half is where months disappear. Ask to be put on the cancellation list, and get on more than one list — you can always decline.

Who pays for the evaluation

Both free routes are genuinely free, and neither is means-tested. For a private evaluation there are three payers worth knowing about.

Medicaid. If your child is under 21 and on Medicaid, EPSDT requires the state to cover medically necessary diagnostic services. This is the strongest coverage position in the system and it is federal, so it works the same in every state.

State-regulated insurance. Pennsylvania requires state-regulated health plans to cover autism diagnosis and treatment. Self-funded employer plans are federally regulated and sit outside that mandate, so check which kind you have before assuming.

The school district. If you disagree with a district evaluation, you can request an independent educational evaluation at public expense. The district either pays for it or has to go to a hearing to defend its own — which is a real lever, and one most families are never told about.
