Getting an autism diagnosis in Texas: what to expect

This guide covers the parts of getting an autism diagnosis that are specific to Texas: the state's Early Childhood Intervention program, how a Texas school evaluation works, and where the three pathways differ. For the clinical basics that are the same everywhere, see our general guide to getting an autism diagnosis.

Who can diagnose autism

There's no single blood test or scan for autism. A diagnosis is a careful clinical judgment, made by a professional with the right training after a thorough evaluation. The professionals who diagnose autism in children are usually a developmental-behavioral pediatrician, a child psychologist, a pediatric neurologist, or a child psychiatrist, and often a team that includes more than one of them.

One thing that trips up a lot of families: a screening at a regular check-up is not a diagnosis. Your pediatrician may give your child a quick autism screen and, if something stands out, refer you onward. But as the CDC and the American Academy of Pediatrics both stress, screening only flags who should be evaluated. It doesn't diagnose.

The three Texas pathways (and how they differ)

This is where Texas families get confused, so it's worth being precise. There are three separate doors, and they don't all give you the same thing.

• Early Childhood Intervention (ECI), birth to 36 months. A statewide Texas program for young children with developmental delays or qualifying conditions. An autism diagnosis isn't required. A child can qualify through a measured developmental delay instead. Anyone can make a referral, including you. The evaluation and case management are free to every family; ongoing therapy uses a sliding scale based on income, and no family is turned away for inability to pay (families on Medicaid or CHIP pay nothing).
• A school district evaluation, age 3 and up. Under federal law, you can request a special-education evaluation from your district in writing, and they have a set timeline (around 45 school days after you give consent) to complete it. No medical diagnosis is required.
• A medical diagnosis, any age. The formal clinical evaluation, done by a developmental pediatrician, psychologist, neurologist, or psychiatrist.

The crucial distinction: a school “autism” eligibility is an educational decision and is not the same as a medical diagnosis. A medical diagnosis, in turn, doesn't automatically create school services either. For insurance-funded therapy like ABA, you need the medical diagnosis, not the school one. Many families pursue both at once, because they do different jobs.

What you get, and what comes next

A medical evaluation ends in a written report explaining the findings in plain language. Keep copies, because that report is the key that unlocks insurance-funded therapy and supports requests at school. From there, most families move in a few directions at once: starting therapies, engaging ECI or the school, and finding support.

If a diagnosis is in hand and you're wondering what's next, our guides on what ABA therapy involves and how Texas Medicaid covers it are good next reads.
