You found an ABA provider you felt good about. You called. And then you heard the words that almost every family hears next: “We’re currently not accepting new clients. We can add you to our waitlist.”

Some families wait three months. Some wait nine. Some are told not to call back for over a year.

If you’re in that position right now, or trying to avoid it, this article is for you. We’ll explain why ABA therapy waitlists are so long — not in vague terms, but structurally — and walk through what you can do in the meantime. We’ll also tell you what actually changes the equation, because there is a path to starting ABA therapy without a six-month wait.

If you’re new to ABA, understanding how ABA therapy helps children with autism will give you useful context before we get into the access problem.

Why Are ABA Therapy Waitlists So Long?

This isn’t a mystery — it’s a math problem with a structural solution.

Traditional ABA therapy is delivered at a clinic or through in-home visits from a therapist who drives to your house. Both models depend on physical proximity. A clinic can only serve as many children as it has physical space and local staff. An in-home provider can only serve as many families as therapists can drive to in a given day.

Meanwhile, demand for ABA therapy has risen steadily. The CDC’s 2025 ADDM data puts ASD prevalence at 1 in 31 children aged 8 — up from 1 in 44 just a few years earlier. More children diagnosed means more families seeking services, all competing for providers anchored to physical geography.

On the supply side, the workforce hasn’t kept up. A systematic review of the US autism healthcare workforce found “significantly restricted availability” of providers. Even as Medicaid expansion — which research shows was associated with a 9% increase in BCBAs per 100,000 children — has helped grow the field, demand for BCBAs increased 58% from 2023 to 2024 alone, according to the Behavior Analyst Certification Board’s employment demand report.

As of January 2026, there are 81,566 BCBAs certified nationally — significant growth, but still deeply mismatched with demand, especially in suburban and rural areas where clinic access is thin.

The result: a family in a mid-sized Texas city or a rural Illinois town might have one or two clinic-based ABA providers within driving distance — and both have waitlists.

Why does the delay matter so much?

Early intervention matters — and delays have measurable consequences. A 2021 study published in the Journal of Autism and Developmental Disorders followed 667 Medicaid-enrolled children with ASD in Minnesota over several years. It found that approximately 70% of children experienced a delay to intensive behavioral intervention, and that children who started earlier had significantly better educational outcomes. The study explicitly lists waitlists as a contributing factor.

The CDC identifies ABA as a behavioral approach with “the most evidence for treating symptoms of ASD.” A 2023 meta-analysis across 11 studies found meaningful effects on intellectual functioning and adaptive behavior for children who received comprehensive ABA-based care. Every month on a waitlist is a month that window isn’t being used.

What to Do Right Now if You’re on a Waitlist

Being on a waitlist doesn’t mean standing still. There’s real work you can do in the months between a diagnosis and the start of formal ABA therapy.

1. Get your child’s insurance authorization started immediately

ABA therapy requires prior authorization — a formal approval process where your insurance plan reviews the clinical documentation before agreeing to cover services — and that process takes time, separate from the provider waitlist. If you’re waiting on a waitlist and haven’t started the authorization process, you’re stacking delays.

Contact your insurance plan now, ask about their ABA therapy authorization requirements, and begin gathering your child’s diagnostic documentation. If your child is covered by Medicaid, ABA therapy covered by Medicaid has more on how that process works in Texas and Illinois.

2. Request school-based services through an IEP evaluation

If your child is school-age (3+), you can request an evaluation for special education services under IDEA (Individuals with Disabilities Education Act). School-based services aren’t a replacement for ABA therapy, but they can provide speech therapy, OT, and behavioral support while you’re waiting for private ABA to begin.

Put the request in writing — email or letter to your school district’s special education department. Schools are required to respond within specific timelines once a written request is received.

3. Ask your pediatrician about early intervention (under age 3)

If your child is under 3, early intervention services are available through your state — and they don’t require a clinic or a waitlist in the same way. In Texas, the program is called Early Childhood Intervention (ECI). In Illinois, it’s the Early Intervention Program. These services come to your home and can begin while you’re waiting for ABA to start.

4. Learn the foundational skills yourself

This one is underused and genuinely powerful: research consistently shows that parent involvement is one of the strongest drivers of better outcomes in autism therapy. A meta-analysis of 26 studies involving 1,738 children found that “the largest effects are found when both parent and clinician implement the intervention.”

You don’t need to wait for a BCBA to start learning. There are BCBA-led parent training courses and books grounded in ABA principles that teach parents the foundations of understanding behavior, responding to communication attempts, and building functional routines. This knowledge doesn’t expire — it becomes even more valuable once formal ABA begins, because you show up as an informed partner rather than starting from scratch.

5. Get on multiple waitlists simultaneously

There’s no rule against being on more than one waitlist. Contact every qualified ABA provider serving your area and ask to be added. When a spot opens, you can choose — and if you’ve started elsewhere by then, you simply decline. Keep notes on who you’ve contacted and when.

When evaluating providers while you wait, knowing how to choose an ABA therapy provider helps you ask the right questions so you don’t end up starting over with a poor-fit provider.

How to Actually Skip the Waitlist

Everything above is about making the best of a waitlist situation. But there’s a different question worth asking: why does the waitlist exist in the first place, and does it have to apply to your family?

The waitlist problem is a clinic-based problem. A clinic can only serve families who live within driving distance. Demand in any given geography will almost always outpace local supply.

Virtual ABA therapy removes geography from the equation entirely.

When ABA therapy is delivered through secure video — a BCBA coaching you and your child in your own home — the provider doesn’t need a physical clinic in your zip code. The supply of qualified BCBAs becomes national, not local. And the bottleneck that creates 6-to-12-month waitlists simply doesn’t apply.

This isn’t a workaround or a compromise. Research supports virtual ABA as effective. A 2016 study by Lindgren et al. compared in-home therapy, clinic-based telehealth, and home-based telehealth across 107 children with autism. All three models achieved a mean reduction in problem behavior of more than 90%. A more recent 2023 study by Gerow et al. found that parents in a telehealth ABA coaching program implemented procedures with 95% accuracy and 85% of therapy goals showed medium, large, or very large improvements.

How virtual ABA therapy works covers the evidence and the mechanics in more detail if you want to go deeper.

What Luna Families Experience

Luna Family Autism provides virtual, family-led ABA therapy for children ages 2–12 in Texas and Illinois. We don’t have a waitlist. Most families start ABA therapy within days — not months.

Here’s what that looks like:

• You call or fill out a brief contact form
• We verify your insurance and confirm coverage — most families pay $0 with Medicaid
• We match you with a BCBA, schedule an assessment, and build your child’s individualized plan
• Sessions happen at home, via secure video, on a schedule that works for your family

The family-led model also means more of the work happens in the moments between sessions. Your BCBA teaches you the same principles they’re using in sessions — so that every dinner table conversation, every bedtime routine, every trip to the grocery store becomes an opportunity to reinforce what your child is learning.

How home-based ABA therapy delivers better skill generalization explains why this matters clinically: skills learned in the home environment generalize more reliably to real life than skills learned in a separate clinic.

You Don’t Have to Wait

If a waitlist is what’s standing between your family and ABA therapy, it’s worth knowing that the waitlist isn’t inevitable — it’s a feature of a specific delivery model that doesn’t apply to every provider.

Virtual ABA therapy, delivered in your home by a qualified BCBA with parent coaching built in, is what the evidence supports and what Luna provides.

Most families who call us are still in the research phase — and that’s exactly the right time to ask questions. You can start ABA therapy within days — not months — no waitlist, no months of waiting to see if there’s a spot.

If cost is a concern, Luna accepts ABA therapy covered by Medicaid in both Texas and Illinois — and most families pay $0 out of pocket. We’ll confirm your coverage before anything begins.
