How Long Is the ABA Therapy Waitlist? (And How to Get Off It Faster)

Published April 6, 2026

The short answer: 3 to 12 months, with the national average around 6 months. In high-demand metro areas like Los Angeles, New York, and Chicago, some families wait 18 months or longer. Rural areas often have no providers at all.

Why ABA waitlists are so long

The core problem is a shortage of Board Certified Behavior Analysts (BCBAs). As of 2024, there are approximately 60,000 certified BCBAs in the US — but demand for ABA therapy has grown faster than the certification pipeline can support.

The 2023 BCBA Task List change added new supervision requirements, and the BACB (Behavior Analyst Certification Board) reported that exam pass rates dropped after the 5th edition rollout. Fewer new BCBAs entering the workforce means existing practices are stretched thin.

Insurance mandates have also expanded access significantly — all 50 states now require most commercial insurance plans to cover ABA therapy. More families can now afford ABA, which has increased demand without a corresponding increase in supply.

What affects waitlist length

Several factors determine how long you'll wait at a specific practice:

• Location: Urban areas have more providers but also more demand. Rural areas may have one provider within 50 miles.
• Insurance: Practices that accept Medicaid often have longer waits because reimbursement rates attract high demand. Out-of-pocket pay can sometimes move faster.
• Child's age: Early intervention slots (ages 2–5) are most in-demand and typically have the longest waits.
• Hours needed: Full-time intensive ABA (25–40 hours/week) is harder to place than a child needing 10–15 hours.
• Provider size: Large clinic networks sometimes have shorter waits than solo practices.

How to check real wait times before you call

Most provider websites don't list waitlist times — you have to call. But there are smarter ways to check before spending hours on the phone:

• Use FindABA's city pages — we display verified waitlist times where providers have shared them directly.
• Check parent Facebook groups for your city — other parents often share current waitlist intel.
• Call the intake coordinator (not the front desk) directly — they have the most accurate information.
• Ask for the waitlist estimate in writing via email — this creates a reference point you can follow up on.

6 strategies to get seen faster

1. Apply to multiple providers simultaneously

This is the single most effective strategy. Most families apply to one practice, wait 6 months, hear nothing, and start over. Apply to 5–10 providers at once. Being on multiple waitlists is not rude — it's standard practice and providers expect it.

2. Ask about the cancellation list

Most practices have a separate cancellation list for families who can accept short-notice openings (24–48 hours). This list moves much faster than the standard waitlist. Explicitly ask: "Do you have a cancellation list, and can you add us to it?"

3. Be flexible on timing and format

If you can accept early morning, late afternoon, or weekend slots, say so explicitly. Practices often fill "unpopular" times first. Telehealth ABA has also expanded significantly — if your child is appropriate for teletherapy, you'll have access to a much wider pool of providers.

4. Start with an assessment-only provider

Some families get a diagnostic assessment completed at one clinic, then use that assessment to move faster at a second clinic's waitlist. Having an existing BCBA assessment in hand can reduce a practice's intake burden and sometimes leads to faster placement.

5. Contact your state's autism resource center

Every state has an autism resource network (often connected to a university). Many have family navigators whose job is specifically to help families find services. They know which local practices are actually accepting new clients, even if websites say otherwise.

6. Ask about parent training while you wait

Many ABA practices offer parent training sessions while your child is on the waitlist. This is ABA-based coaching for caregivers, covered by most insurance plans, and it means your child is making progress even before formal therapy starts. Ask any practice you're waitlisted with if they offer this.

What to do if you can't find any availability

If you've contacted 10+ providers and found no availability, escalate to these resources:

• Your state's Medicaid waiver program — many states have HCBS waivers that fund ABA and may have different provider networks than commercial insurance.
• Your child's school district — if your child is school-age, IDEA requires the district to provide appropriate services. ABA may be available through the school IEP process.
• Regional autism centers at universities — many major universities run ABA clinics with supervised student therapists at reduced cost.
• Your insurance company's care advocate — insurers are legally required to help members find in-network providers within access standards. Call the member services number and request a case manager.
