Pittsburgh's early intervention system forks by address, not just by age. Every child under 3 in Allegheny County goes through the same countywide agency, but at age 3 the system splits: families inside Pittsburgh's city limits are served by Pittsburgh Public Schools, while everyone else in the county moves to the Allegheny Intermediate Unit. Knowing which door applies to your address avoids a redirected phone call.

This guide lists the phone numbers and links behind each door, the evaluation pathways at UPMC Children's Hospital of Pittsburgh and the Watson Institute, the county's intellectual disability and autism access point, and the PH-95 Medicaid route that many Pennsylvania families can use regardless of income.

Statewide programs, numbers, and rights are on the Pennsylvania page. This page adds the local entry points that are specific to Pittsburgh (Allegheny County).

Early intervention under 3: Alliance for Infants and Toddlers (birth–3), then a city/county-split preschool system (3–5)

The Alliance for Infants and Toddlers has served as Allegheny County's Early Intervention Service Coordination Agency for children birth to 3 since 1996, covering the whole county from one intake line. At age 3, responsibility splits by residence: a child who lives inside the City of Pittsburgh moves to Pittsburgh Public Schools' own Early Intervention Program, run out of the district's Early Childhood Education department, while a child anywhere else in Allegheny County moves to the Allegheny Intermediate Unit's Preschool Early Intervention Program, which served over 4,000 children across 500 sites in the 2024–25 school year. Eligibility for either preschool program requires a 25% developmental delay in one or more areas plus a need for specially designed instruction — not a medical diagnosis. At school age, responsibility shifts again, to the local school district.

School districts and special education

For a school-age child in a district school, put an evaluation request in writing to the school; Pittsburgh Public Schools centralizes this through its Program for Students with Exceptionalities (PSE) office. Pittsburgh also has a notable option outside the district system: Spectrum Charter School, in Monroeville, describes itself as the first autism-specific charter school in the United States and is tuition-free and publicly funded, built for students who have not thrived in a traditional classroom.

• Pittsburgh Public Schools — Program for Students with Exceptionalities (PSE) — 412-529-3132; 2323 Brighton Road, Pittsburgh, PA 15212
• Spectrum Charter School — 412-374-8130; a tuition-free public charter in Monroeville built specifically to educate autistic students — note it sits just outside Pittsburgh's city limits

Evaluation and diagnosis pathways in Pittsburgh

These are hospital and university programs with public intake information. Listing here is informational — it is not a recommendation, and it is not medical advice. Public school evaluation is free and does not require any of these.

• UPMC Children's Hospital of Pittsburgh — Autism Evaluations — autism evaluation for ages 18 months to 7 years using ADOS-2 testing, cognitive and behavioral assessment, medical record review, and a parent interview; a standard evaluation runs 2–3 hours, with an extended option up to 5 hours for ages 5–7 · 412-692-5325
• The Watson Institute — diagnostic testing and TEACCH-based programming for ages 3–21 across five locations (Sewickley, Pittsburgh, Sharpsburg, Bridgeville/South Fayette, Wexford), plus intensive behavioral health services delivered under IBHS · 412-741-1800
• The Children's Institute of Pittsburgh — ABA therapy for ages 18 months to 21 years alongside in-house speech-language, occupational, and physical therapy — one of the few Pittsburgh providers combining ABA with a full therapy team on one campus · 412-420-2400

Disability services and waivers: Allegheny County Department of Human Services — Office of Developmental Supports

The Office of Developmental Supports is Allegheny County's registration point for intellectual disability, autism, and other developmental disability services, including eligibility for Pennsylvania's Medicaid waivers; registering here assigns a Supports Coordinator and is a separate step from enrolling in early intervention or requesting a school evaluation. Community Care Behavioral Health Organization (CCBH) is the separate entity that administers HealthChoices behavioral-health coverage for Allegheny County, and it is what funds and authorizes IBHS-delivered ABA for children on Medicaid.

Documented waits and access notes

Wait times change. Each note below links to the public source it came from — confirm current status directly with the program.

• Pittsburgh developmental psychologist Dr. Jessie Northrup was quoted in 2025 local reporting saying local waitlists for autism testing can run six months to a year, with advice to join more than one waitlist at once. (source)
• Whichever office produces the evaluation report — Pittsburgh Public Schools' PSE office or Spectrum Charter — Pennsylvania then gives the IEP team just 30 calendar days to hold the meeting and finish the IEP. (source)
• Act 62 caps a Pittsburgh family's state-regulated autism insurance benefit around $36,000 annually (adjusted for inflation) through age 20, and it has no reach into a self-funded employer plan. (source)
