How to Get an Autism Diagnosis for Your Child in Texas: A Step-by-Step Guide

Receiving an autism diagnosis for your child is one of the most significant moments in your family's journey. But before you can access ABA therapy and many other services in Texas, you need a formal diagnosis. The process can feel overwhelming, long waitlists, confusing referrals, and uncertainty about what to expect. This guide breaks down the autism diagnosis process in Texas step by step, so North Texas families can navigate it with confidence.

Step 1: Talk to Your Pediatrician

Your child's pediatrician is the first stop. Pediatricians are required to screen for autism at 18-month and 24-month well-child visits using tools like the M-CHAT-R/F (Modified Checklist for Autism in Toddlers). If you have concerns outside of these appointments, request a dedicated developmental screening visit.

Be specific and concrete when sharing your concerns. Document examples: 'He doesn't respond to his name 80% of the time,' not just 'He seems in his own world.' The more objective your description, the more actionable your pediatrician's response will be.

Step 2: Request a Referral for a Formal Evaluation

If your pediatrician has concerns, they will refer your child for a comprehensive autism evaluation. In Texas, evaluations are performed by: developmental pediatricians (usually the first stop), pediatric neurologists, child psychologists or neuropsychologists, and university-based developmental clinics (UT Southwestern's CTRD, Baylor's CARE Center, etc.).

Waitlists for developmental pediatricians in North Texas can be long, often 6-12 months or more. Request the referral as soon as your pediatrician identifies concerns. In the meantime, pursue other steps simultaneously.

Step 3: Apply for Texas Early Childhood Intervention (ECI)

If your child is under 3, apply for Texas Early Childhood Intervention (ECI) services immediately. ECI is a state-funded program that provides free early intervention services, including speech therapy, occupational therapy, and in some cases behavioral support, to eligible children with developmental delays, regardless of diagnosis status. You do not need an autism diagnosis to qualify for ECI.

Contact Texas ECI at 1-877-787-8999 or visit hhs.texas.gov/eic to apply. ECI is one of the most valuable resources available to North Texas families while awaiting a formal diagnosis.

Step 4: Prepare for the Autism Evaluation

A comprehensive autism evaluation typically includes: parent interview and developmental history, standardized autism assessment tools (ADOS-2, ADI-R), cognitive and developmental testing, speech/language evaluation, and sometimes occupational therapy assessment.

Bring your developmental history notes, any videos of concerning behaviors at home, school or daycare reports, and previous evaluations or therapy notes. The more context you provide, the more accurate and useful the evaluation will be.

Step 5: After the Diagnosis

If your child receives an ASD diagnosis, the evaluation report will typically include specific recommendations for treatment, including ABA therapy. The diagnostic report is the key document you need to: begin the insurance prior authorization process for ABA therapy, enroll in Texas ECI (if under 3), pursue an IEP evaluation through your child's school district (under IDEA), and contact ABA providers like Belong ABA.

Do not wait to act on the diagnosis. Contact Belong ABA Therapy at (469) 294-9924 as soon as you receive the report. We will begin the insurance verification and intake process immediately.
