How to Choose and Vet an ABA Provider

Picking an ABA provider is one of the biggest decisions a parent makes after a diagnosis. You are handing a stranger many hours a week with your child, often for a year or more. This guide gives you the facts to check and the questions to ask, so you can tell a strong provider from a weak one. It does not tell you whether to do ABA at all. That is your call, and there is honest disagreement about it, covered near the end.

The two credentials behind ABA

Most ABA services are delivered by two roles. Knowing which is which tells you a lot about a program.

• A BCBA is a Board Certified Behavior Analyst. This is the clinician who assesses your child, writes the treatment plan, sets the goals, and supervises the day-to-day work. A BCBA holds a master's degree, has passed a national exam, and is certified by the Behavior Analyst Certification Board (BACB). Source: BACB Certificant Registry, verified Jul 19, 2026.
• An RBT is a Registered Behavior Technician. This is the person in the room with your child for most of the hours. An RBT completes a 40-hour training, passes a competency check, and works under a BCBA's supervision. An RBT is not allowed to design the program alone.

If a company cannot tell you the name of the BCBA who will supervise your child, that is a problem. The BCBA is who you are really hiring.

Verify the provider yourself, for free

The BACB keeps a public online registry of every certified BCBA and RBT. You can search it by name to confirm a person is certified and in good standing. It also shows discipline.

• Search the BACB Certificant Registry at bacb.com and look up the BCBA by name. Confirm the certification is current, not expired or revoked. Source: BACB Certificant Registry.
• Check for sanctions. On the registry, a "†" symbol next to a certificant's status means the BACB has published one or more sanctions or actions against that person, which you can open and read. Source: BACB Certificant Registry, verified Jul 19, 2026.
• Do the same for the RBTs when you can get names, and re-check yearly. Certifications lapse.

What good supervision looks like

An RBT running your child's sessions is normal. An RBT running them with almost no oversight is not. The BACB sets a floor.

• An RBT must receive supervision for at least 5% of the hours they spend giving services each month. Source: BACB Registered Behavior Technician Handbook.
• Supervision must include at least two contacts each month, and in at least one of them the supervisor has to watch the RBT actually working with a child. Phone calls and email do not count as the observation. Source: BACB Registered Behavior Technician Handbook, verified Jul 19, 2026.
• Only a BCBA, BCaBA, or BCBA-D can supervise an RBT. Source: BACB Registered Behavior Technician Handbook.

Caseload is the other number to ask about. A BCBA stretched across too many children cannot supervise any of them well. The Council of Autism Service Providers (CASP), the main trade body for ABA providers, publishes practice guidelines that suggest a BCBA carry roughly 10 to 15 children when the work is focused on a few goals, or 6 to 12 children when it covers many developmental areas at once. Source: CASP Applied Behavior Analysis Practice Guidelines for the Treatment of Autism Spectrum Disorder. Ask the BCBA how many children they currently supervise. A number far above these ranges is a red flag.

What a real initial assessment looks like

Before any therapy starts, a good provider does a full assessment. This is where the BCBA meets your child, watches how they play and communicate, and talks with you about what your family actually needs. The assessment produces a written treatment plan with specific goals and a recommended number of hours.

CASP describes two broad models. One works on many developmental areas at once and tends to run 30 to 40 hours a week. The other, called focused ABA, targets a smaller set of specific goals and runs fewer hours. Source: CASP Applied Behavior Analysis Practice Guidelines. The right number is the one the assessment justifies for your child, not a fixed package the company sells to everyone.

Green signs and red flags in the staffing model

Use this when you tour a clinic or interview a provider.

Green signs:

• The BCBA is named, certified, and supervises a reasonable caseload.
• You are allowed to watch sessions and are told you can drop in.
• Goals are tied to your family's priorities and your child's own way of communicating.
• The team stops or changes course when your child is in real distress.
• They share session data with you and explain it in plain words.
• They can tell you what progress looks like and roughly when your child would no longer need services. This is called discharge criteria, and a serious provider has them.

Red flags:

• The same 40-hour plan is pushed on every child regardless of the assessment.
• You are not allowed to observe sessions.
• Goals center on forced eye contact, "quiet hands," or stopping harmless self-soothing like hand-flapping.
• RBTs work long hours with little sign of the BCBA supervision described above.
• The provider cannot explain how a session ends when your child is upset, or when therapy itself would end.

The honest disagreement about ABA

You will hear strong views on both sides, and you deserve to know them before you choose.

Many families report that ABA helped their child with safety, communication, and daily skills. At the same time, the Autistic Self Advocacy Network (ASAN), an advocacy group run by autistic people, has raised ethical concerns about ABA. ASAN argues that some ABA has focused on making autistic children act non-autistic rather than teaching skills the child actually needs, and that autistic people should have the final say in what a therapy works on.

We are not going to settle that debate for you. What we will say is this: you can insist on respectful, assent-based care whichever provider you pick. Assent means your child's ongoing willingness to take part, shown through their behavior, and the BACB Ethics Code expects behavior analysts to seek it and to protect client dignity. Source: Ethics Code for Behavior Analysts (2022). Modern, assent-based practice follows the child's lead, treats distress as a signal to stop and adjust, and never treats compliance as the goal in itself. Rigid compliance training, where a child is drilled to obey and their protests are ignored, is the version of ABA that draws the strongest criticism. You are allowed to ask a provider directly which one they practice, and to walk away from the answer you do not like.

The Florida piece

If your child is on Florida Medicaid and under 21, ABA is a covered benefit, called "behavior analysis" in state rules. It has no annual dollar cap the way private insurance often does, which makes it a strong funding path. Two Florida realities to plan around:

• Prior authorization is required, and hours are approved in blocks based on the assessment, then reassessed. Approvals can shrink or need renewal, so keep the doctor's order and evaluation current. Source: AHCA Behavior Analysis Services Information page, verified Jul 19, 2026. See medicaid-managed-care-and-aba-access.
• Waitlists for an actual provider slot are common even after coverage is approved, because provider capacity is the bottleneck in many Florida metros, not the benefit itself.

Ask each provider for their current wait when you call.

Questions to ask on the first call

Print this. Ask every provider the same questions and compare the answers.

Credentials and supervision:

1. Who is the BCBA who will supervise my child, and what is their full name so I can look them up on the BACB registry?
2. How many children does that BCBA currently supervise?
3. How often will a BCBA watch my child's sessions in person each month?

The plan and the goals:

1. How do you decide how many hours my child needs, and how many are you recommending?
2. How will my family's priorities show up in the written goals?
3. Can you show me an example goal, and tell me why it matters for my child's life?

Respect and safety:

1. What do you do in a session when my child is crying, refusing, or clearly done?
2. What is your policy on assent, meaning my child's willingness to take part?
3. Can I watch sessions whenever I want, in person or by video?

Data and the finish line:

1. How and how often will you share my child's progress data with me?
2. What does progress look like, and how will we know when my child no longer needs services?

Access and cost:

1. Do you take my Medicaid plan or insurance, and what is your current wait for an open slot?

Take notes on the call. The provider who answers all twelve without dodging is the one worth trusting with your child's hours.
