Autism Evaluation in Connecticut: 2026 Guide
There are three ways to get a child evaluated for autism in Connecticut. The private clinic route gives you a medical diagnosis and usually involves a 6 to 18 month wait. The Early Intervention route serves children under 3 and starts services without requiring a diagnosis. The public school route, for ages 3 and up, decides whether the school will provide services through an IEP. You can run more than one of these at once.
The three pathways for an autism evaluation in Connecticut
1. Early Intervention (under age 3): Birth to Three
Free, no diagnosis or doctor referral required, federally guaranteed under IDEA Part C. Evaluation, assessment, and the initial IFSP meeting must occur within 45 calendar days of referral to the local Birth to Three program, per Part C federal rule as implemented by the CT Office of Early Childhood. Parents or referring providers can call the statewide Child Development Infoline at 1-800-505-7000 to start a referral. Services typically begin within 30 days of the signed IFSP.
Self-refer to Birth to Three →2. Private developmental pediatrician or autism clinic
Typical waitlist in Connecticut: 6 to 18 months. Cost with insurance: Copay or coinsurance after deductible varies by plan; behavioral therapy including ABA covered without dollar or visit caps under Conn. Gen. Stat. §38a-488b and §38a-514b (caps removed by CT Insurance Department Bulletins HC-96 and HC-99 in 2014). Without insurance: $1,800 to $5,000 for a full diagnostic battery; Fairfield County practices tend to run higher than Hartford or New Haven.
The Yale Child Study Center in New Haven runs a two-day multidisciplinary autism diagnostic evaluation; the Yale Child Study Center Westport satellite handles anxiety, ADHD, executive functioning, and behavioral evaluations but does not perform autism diagnostic assessments (those are referred to New Haven). Connecticut Children's Autism Spectrum Assessment Program (ASAP) in Hartford and the Mary W. Parker Autism Center at the Institute of Living (Hartford HealthCare) also evaluate. Wheeler Clinic operates an Autism Diagnostic Evaluation Program with multiple locations. Fairfield County waitlists run longer than the rest of the state.
3. School district evaluation (age 3 and up)
Free, federally guaranteed under IDEA Part B (Child Find). Submit a written referral to your district's Director of Special Education or building principal; verbal requests do not start the timeline. Connecticut calls the special education team the Planning and Placement Team (PPT). The district must convene a PPT meeting and obtain written parental consent to evaluate before the 45 school day clock starts running.
Timeline: Per Conn. Agencies Regs. §10-76d-13, the initial evaluation must be completed within 45 school days of written parental consent. CT formally retired the federal 60-calendar-day timeline effective with the 2020-2021 school year and now uses the 45 school day rule exclusively, except that out-of-district placements get a 60 school day window per the same regulation.

Insurance mandate
Yes. Connecticut Public Act 09-115 (Substitute Senate Bill 301), effective Jan 1, 2010 and codified at Conn. Gen. Stat. §38a-488b (individual policies) and §38a-514b (group policies), requires state-regulated plans to cover the diagnosis and treatment of autism spectrum disorder including behavioral therapy. CT Insurance Department Bulletins HC-96 and HC-99 (2014) removed prior dollar and visit caps on ABA.
Medicaid waiver: Connecticut Medicaid Waiver for Persons with Autism Spectrum Disorder (DSS Division of Autism Spectrum Services)
Connecticut residents age 3 and older with a documented autism spectrum disorder diagnosis, an IQ above the intellectual-disability range (no co-occurring intellectual disability that would qualify the person for the DDS ID waiver instead), and substantial functional limitations in at least two major life activity areas. Only the applicant's own income is counted, not parents' income. Per Conn. Gen. Stat. §17a-215g the agency must report annually on the waitlist. Children under 3 with autism access services through Birth to Three instead. As of late 2025 lawmakers expanded capacity to 690 slots, though the state estimated about half would not be filled in time due to case-manager capacity constraints. // VERIFY 2026-05-18: a specific waitlist headcount could not be sourced to a .gov page; revisit when the next DSS §17a-215g annual report is posted to portal.ct.gov. Note: the waitlist for full waiver enrollment in Connecticut is currently around 10 years; apply early.

Frequently asked questions
- How long is the autism evaluation waitlist in Connecticut?
- Private autism evaluations in Connecticut typically take 6 to 18 months from referral to evaluation date. The state's Early Intervention program (Birth to Three) 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 Connecticut?
- Yes, for children age 3 and up. Submit a written referral to your district's Director of Special Education or building principal; verbal requests do not start the timeline. Connecticut calls the special education team the Planning and Placement Team (PPT). The district must convene a PPT meeting and obtain written parental consent to evaluate before the 45 school day clock starts running. Per Conn.

CT formally retired the federal 60-calendar-day timeline effective with the 2020-2021 school year and now uses the 45 school day rule exclusively, except that out-of-district placements get a 60 school day window per the same regulation. 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 Connecticut?
- Early Intervention (under 3) and school evaluations (3+) are free. Private evaluations: copay or coinsurance after deductible varies by plan; behavioral therapy including aba covered without dollar or visit caps under conn. gen. stat. §38a-488b and §38a-514b (caps removed by ct insurance department bulletins hc-96 and hc-99 in 2014); $1,800 to $5,000 for a full diagnostic battery; fairfield county practices tend to run higher than hartford or new haven.

- Do I need a referral from my pediatrician to start in Connecticut?
- No, not for Birth to Three (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 Connecticut. What can I do right now?
- Three things, in order. First, refer to Birth to Three (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 Connecticut.
