Autism Evaluation in California: 2026 Guide

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. Per Cal. Ed. Code §56321, the district must provide a written assessment plan within 15 calendar days of referral. California Ed. Code §56043 sets a 60-calendar-day outer window from written parental consent to the IEP team meeting, EXCLUDING any school vacation longer than 5 schooldays. The federal 30-day-from-eligibility floor (34 CFR §300.323(c)(1)) is preserved per §56344(a) as an alternate trigger inside the 60-day cap, so the IEP meeting must occur within 30 days of an eligibility determination if that's sooner than the 60-day outer deadline. 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: copay or coinsurance after deductible varies by plan; aba covered under the sb 946 state mandate; $1,800 to $5,500 for a full diagnostic battery (ados-2 + adi-r + cognitive testing). California SB 946 (signed Oct 2011, effective July 1, 2012; codified at Cal. Ins. Code §10144.51 and Cal. Health & Safety Code §1374.73) requires fully-insured plans to cover behavioral health treatment for autism including ABA, with no monetary or 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 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 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.

What is the California autism insurance mandate?

California SB 946 (signed Oct 2011, effective July 1, 2012; codified at Cal. Ins. Code §10144.51 and Cal. Health & Safety Code §1374.73) requires fully-insured plans to cover behavioral health treatment for autism including ABA, with no monetary or visit cap.

Does California have a Medicaid waiver waitlist for autism services?

California does not maintain a multi-year waitlist for its primary developmental disability Medicaid waiver. Anyone of any age with a qualifying developmental disability is entitled to Regional Center services under the Lanterman Act. No income test, no funding waitlist for the entitlement itself. Self-Determination Program (statewide since July 1, 2021) is one voluntary delivery option within the RC system; Medi-Cal acts as supplemental coverage. Even with no waitlist, the eligibility and Medicaid determination process can still take months, so apply the day you have a diagnosis or strong evidence of substantial functional impairment rather than waiting.
