Autism Testing and Evaluation in Texas (2026 Guide)
Parents in Texas have three options for getting an autism evaluation, and the options do different things. A private clinic produces a medical diagnosis but usually means waiting 4 to 12 months and dealing with insurance. Early Intervention is free for children under 3. The local school district evaluates for educational eligibility once a child turns 3. Running two paths in parallel is allowed, and is often the right move.
The three pathways for an autism evaluation in Texas
1. Early Intervention (under age 3): Early Childhood Intervention (ECI)
Free, no diagnosis or doctor referral required, federally guaranteed under IDEA Part C. ECI must complete pre-enrollment, evaluation, and the initial IFSP within 45 days of referral per 26 TAC §350.708. Services typically begin within 30 days of the signed IFSP.
Self-refer to Early Childhood Intervention (ECI) →2. Private autism testing: developmental pediatrician or clinic
Typical waitlist in Texas: 4 to 12 months. Cost with insurance: Copay or coinsurance after deductible varies by plan; ABA covered under TX Insurance Code §1355.015 (HB 451 (2007) as amended by SB 1484 (2013)). Without insurance: $1,500 to $4,500 for a full diagnostic battery; some clinics offer sliding-scale fees.
The Meyer Center for Developmental Pediatrics and Autism at Texas Children's Hospital (Houston), Dell Children's (Austin), Children's Health (Dallas), and UT Health Science Center San Antonio all run multidisciplinary evaluations. Baylor College of Medicine Developmental Pediatrics also evaluates.
3. School district evaluation (age 3 and up)
Free, federally guaranteed under IDEA Part B (Child Find). Submit a written request (email is fine) to your campus special education coordinator, with a copy to the district's Director of Special Education. Texas Education Code requires the district to respond within 15 school days.
Timeline: Texas Education Code §29.004 (19 TAC §89.1011) sets a stricter timeline than federal: 45 school days from signed parental consent to completed Full Individual Evaluation (FIE), then 30 calendar days to convene the IEP meeting.
Where to get your child tested for autism in Texas
When parents search for autism testing or an autism assessment, they usually mean a clinical diagnosis. In Texas that comes from the private pathway above: a developmental pediatrician, child psychologist, or autism clinic runs the assessment and issues the diagnosis, with a typical wait of 4 to 12 months. A school district can also test your child for educational eligibility under the autism category, but that determination is not the same as a medical diagnosis, and insurers and Medicaid waivers usually ask for the clinical one. If your child is under 3, Early Childhood Intervention (ECI) can start a developmental screening and services right away, with no diagnosis required, while you wait for the full assessment.

Insurance mandate
Yes. TX Insurance Code §1355.015 requires state-regulated plans to cover diagnosis and treatment of autism including ABA from initial diagnosis through age 9. The statute provides that coverage may not be discontinued solely because the enrollee turns 10 and continues to need treatment. Plan-level deductibles, copays, and coinsurance apply consistent with §1355.015(d).
Medicaid waiver: Home and Community-based Services (HCS) waiver
Children and adults with intellectual or developmental disabilities. Income limits apply, but the child's income is what's counted, not the parents' (deeming waiver). The interest list (~68,000 Texans) typically waits 10 to 15+ years. Note: the waitlist for full waiver enrollment in Texas is currently around 13 years; apply early.

Frequently asked questions
- Where can I get my child tested for autism in Texas?
- A clinical autism test (also called an assessment) in Texas comes from a private developmental pediatrician, child psychologist, or autism clinic, with a typical wait of 4 to 12 months. Early Childhood Intervention (ECI) can evaluate children under 3 within 45 days under federal law, and your school district can assess children 3 and up for educational eligibility. The private clinical assessment is the one that produces a medical diagnosis that insurers and Medicaid waivers usually require.
- How long is the autism evaluation waitlist in Texas?
- Private autism evaluations in Texas typically take 4 to 12 months from referral to evaluation date. The state's Early Intervention program (Early Childhood Intervention (ECI)) is faster for children under 3, with evaluation completed within 45 days of referral by federal law.
- Can the school evaluate my child for autism in Texas?
- Yes, for children age 3 and up. Submit a written request (email is fine) to your campus special education coordinator, with a copy to the district's Director of Special Education. Texas Education Code requires the district to respond within 15 school days. Texas Education Code §29.004 (19 TAC §89.1011) sets a stricter timeline than federal: 45 school days from signed parental consent to completed Full Individual Evaluation (FIE), then 30 calendar days to convene the IEP meeting. A school eligibility determination of "Autism" qualifies the child for an IEP and special education services, but it is not the same as a medical diagnosis from a developmental pediatrician (which insurance and Medicaid waivers may require separately).
- Who pays for autism evaluation in Texas?
- Early Intervention (under 3) and school evaluations (3+) are free. Private evaluations: copay or coinsurance after deductible varies by plan; aba covered under tx insurance code §1355.015 (hb 451 (2007) as amended by sb 1484 (2013)); $1,500 to $4,500 for a full diagnostic battery; some clinics offer sliding-scale fees. TX Insurance Code §1355.015 requires state-regulated plans to cover diagnosis and treatment of autism including ABA from initial diagnosis through age 9. The statute provides that coverage may not be discontinued solely because the enrollee turns 10 and continues to need treatment. Plan-level deductibles, copays, and coinsurance apply consistent with §1355.015(d).
- Do I need a referral from my pediatrician to start in Texas?
- No, not for Early Childhood Intervention (ECI) (Early Intervention). You can self-refer directly using the program's referral page. For private clinics, some require a pediatrician's referral form for insurance billing; many do not. Always call the clinic to confirm before joining the waitlist, since being on the wrong list wastes months.
- My child is on a long waitlist in Texas. What can I do right now?
- Three things, in order. First, refer to Early Childhood Intervention (ECI) (under 3) or your school district (3+); these run on legal deadlines, not waitlists. Second, document what you see at home (videos, behavior patterns, sleep, sensory triggers) so the eventual evaluation has data to work with. Third, start no-diagnosis-required supports: visual schedules, sensory accommodations, predictable routines. Our free 30-day plan tool combines all three based on your specific situation in Texas.
