Autism Evaluation in California: 2026 Guide
Three pathways exist in California 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 6 to 18 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 California
1. Early Intervention (under age 3): Early Start
Free, no diagnosis or doctor referral required, federally guaranteed under IDEA Part C. Initial intake call within 2 to 4 weeks of referral, full multidisciplinary evaluation within 45 days (state law). Services typically start 30 to 60 days after the IFSP meeting.
Self-refer to Early Start →2. Private developmental pediatrician or autism clinic
Typical waitlist in California: 6 to 18 months. Cost with insurance: $30 to $200 copay typical after deductible, ABA covered under state mandate. Without insurance: $1,800 to $5,500 for a full diagnostic battery (ADOS-2 + ADI-R + cognitive testing).
UCLA Center for Autism Research and Treatment, Stanford Autism Center, Children's Hospital Los Angeles, UCSF Benioff, and the network of 21 Regional Centers all run developmental evaluations.
3. School district evaluation (age 3 and up)
Free, federally guaranteed under IDEA Part B (Child Find). Submit a written request to your district's special education director (find via your school's main office or the district website). California requires the request in writing to start the timeline; verbal requests do not count.
Timeline: California follows the federal IDEA 60-calendar-day timeline from signed parental consent to completed assessment, with the IEP meeting within 30 days after that.

Insurance mandate
Yes. California SB 946 (2011) requires fully-insured plans to cover behavioral health treatment for autism, including ABA, with no annual visit cap.
Medicaid waiver: Self-Determination Program (Regional Center system)
Children of any age with a qualifying developmental disability. Income is not a factor for the Regional Center entitlement; Medi-Cal acts as supplemental coverage.
Tax-advantaged savings: CalABLE
ABLE accounts let families save for disability-related expenses without losing means-tested benefits like Medicaid or SSI. Open a CalABLE account →

Frequently asked questions
- How long is the autism evaluation waitlist in California?
- Private autism evaluations in California typically take 6 to 18 months from referral to evaluation date. The state's Early Intervention program (Early Start) 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 California?
- Yes, for children age 3 and up. Submit a written request to your district's special education director (find via your school's main office or the district website). California requires the request in writing to start the timeline; verbal requests do not count. California follows the federal IDEA 60-calendar-day timeline from signed parental consent to completed assessment, with the IEP meeting within 30 days after that. 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 California?
- Early Intervention (under 3) and school evaluations (3+) are free. Private evaluations: $30 to $200 copay typical after deductible, aba covered under state mandate; $1,800 to $5,500 for a full diagnostic battery (ados-2 + adi-r + cognitive testing). California SB 946 (2011) requires fully-insured plans to cover behavioral health treatment for autism, including ABA, with no annual visit cap.
- Do I need a referral from my pediatrician to start in California?
- No, not for Early Start (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 California. What can I do right now?
- Three things, in order. First, refer to Early Start (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 California.
