Autism Evaluation in Texas: 2026 Guide
Three pathways exist in Texas to get your child evaluated for autism. Each one has a different timeline, different cost, and a different decision-maker. Private clinics typically have a 4 to 12 month waitlist; Early Intervention and school evaluations have a 45 to 60 day legal deadline. You can pursue more than one path at the same time.
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 contact the family within 2 days of referral and complete the eligibility evaluation within 45 days. Services typically begin 30 days after the IFSP meeting.
Self-refer to Early Childhood Intervention (ECI) →2. Private developmental pediatrician or autism clinic
Typical waitlist in Texas: 4 to 12 months. Cost with insurance: $30 to $150 copay typical, ABA covered under HB 451 mandate up to age 10. Without insurance: $1,500 to $4,500 for a full diagnostic battery; some clinics offer sliding-scale fees.
Texas Children's Hospital Autism Center (Houston), Dell Children's (Austin), Children's Health (Dallas), UT Health Science Center San Antonio, and the Thompson Autism Center (CHOC) all run multidisciplinary evaluations.
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 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.

Insurance mandate
Yes. Texas HB 451 (2007) requires state-regulated plans to cover ABA and other autism services for children diagnosed before age 10, through age 10.
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). Note: the waitlist for full waiver enrollment in Texas is currently around 16 years; apply early.
Tax-advantaged savings: Texas ABLE
ABLE accounts let families save for disability-related expenses without losing means-tested benefits like Medicaid or SSI. Open a Texas ABLE account →

Frequently asked questions
- 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 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: $30 to $150 copay typical, aba covered under hb 451 mandate up to age 10; $1,500 to $4,500 for a full diagnostic battery; some clinics offer sliding-scale fees. Texas HB 451 (2007) requires state-regulated plans to cover ABA and other autism services for children diagnosed before age 10, through age 10.
- 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 state'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.
