ABA Therapy Waitlists & Provider Demand

ABA therapy wait times range from 1–3 months in well-served states like Massachusetts, Connecticut, and New Hampshire to 9–12+ months in underserved states like Wyoming, Mississippi, and Montana. The national average is roughly 3–12 months depending on location, insurance, and provider availability.

The US has approximately 48,352 BCBAs but an estimated 362,500 are needed to adequately serve the 2.9 million children with autism. Training a BCBA requires a master’s degree, 2,000+ supervised fieldwork hours, and passing a national exam — a pipeline that takes 3–5 years. Meanwhile, autism prevalence continues to rise (now 1 in 31 children).

Wyoming (7.5 BCBAs per 100K), Mississippi (8.1), Montana (8.5), Oklahoma (9.8), and Iowa (10.2) have the lowest BCBA density in the nation. Families in these states often wait 9–12+ months for ABA services and may need to travel or use telehealth.

Massachusetts (55.1 BCBAs per 100K), New Hampshire (45.6), Connecticut (41.9), New Jersey (39.2), and Hawaii (36.7) lead the country in BCBA density. Families in these states typically wait 1–3 months for ABA services.

Families can reduce wait times by joining multiple provider waitlists simultaneously, considering both center-based and in-home ABA options, asking about cancellation lists, exploring telehealth ABA for initial assessments, and looking at providers slightly outside their immediate area. Starting the insurance authorization process early also helps.

The shortage can impact quality in several ways: higher caseloads per BCBA, less supervision time per RBT, and pressure on providers to see more clients than recommended. Families should ask prospective providers about their BCBA-to-client ratio and supervision frequency.

Yes. The US has 186,880 RBTs and 8,629 BCaBAs who deliver direct ABA services under BCBA supervision. RBTs provide the majority of 1:1 therapy hours. However, BCBAs are still required for assessments, treatment planning, and supervision — so the BCBA shortage remains the primary bottleneck.

Many states now allow telehealth ABA for parent training, assessments, and supervision sessions. While direct 1:1 therapy typically requires in-person delivery, telehealth can help families get started on parent-implemented strategies while waiting for a full in-person program to begin.
