How many hours of ABA will my child actually get — and who decides?

Nobody on the internet can tell you the right number of hours for your child, and this page won’t try. What it can tell you is who sets that number, what every one of those hours is required to carry, and the arithmetic that follows from a rule the certification board publishes in plain sight.

Sourced to the BACB RBT Handbook, Updated 06/2026 (pages 15–17). Every quoted sentence below is the board’s wording, not ours. Written 4 September 2026.

The short version. Your child’s hours come from a clinical assessment and then from whoever is paying. The board doesn’t set them. What the board does set is the supervision that must sit behind those hours — a monthly floor, a minimum number of real-time meetings, and at least one occasion where the supervisor watches the actual work. Those are the facts you can check.

1. Who actually decides the number

Three different parties touch the number, in this order, and only one of them is in the room with your child:

We aren’t any of those three. Special Learning doesn’t assess children, doesn’t deliver ABA services, and has no view on what your child’s hours should be. If you want to know how coverage works, that’s a separate question with its own answer: does insurance cover autism therapy.

2. What every delivered hour is required to carry

Most Registered Behavior Technicians (RBTs) work under supervision by design — it’s not a sign that something is wrong. The board is explicit about the minimum:

“Amount of supervision. You must obtain ongoing supervision for a minimum of 5% of the hours you spend providing behavior-analytic services each calendar month.”

— BACB RBT Handbook, Updated 06/2026, p.16

And it’s explicit about the shape of that supervision, which matters more than the percentage:

3. The arithmetic, which nobody prints

A percentage is hard to picture. Hours aren’t. The table below is our arithmetic applied to the board’s 5% rule — it’s derived, not quoted, and a month is taken as 4.33 weeks.

If your child receivesThat’s aboutSupervision floor that month
10 hours a week~43 hours a month~2.2 hours
20 hours a week~87 hours a month~4.3 hours
30 hours a week~130 hours a month~6.5 hours
40 hours a week~173 hours a month~8.7 hours

Read this as a floor, not a target. The 5% is the minimum an RBT must obtain to keep their own certification in good standing. It’s not a promise about the quality of your child’s programme, and a provider doing careful work will often be well above it. A number at or barely above the floor isn’t evidence of anything on its own — it’s a reason to ask the next question rather than a verdict.

4. What you can check yourself, in about a minute

The board runs a public register, and it shows more than whether someone is certified. For an RBT it also shows who their supervisor is:

“If at any time you do not have a qualified RBT Supervisor or RBT Requirements Coordinator, you may not practice, and your certification will be considered inactive.”

— BACB RBT Handbook, Updated 06/2026, p.15

An RBT isn’t a credential a person holds on their own. It exists only inside a supervised relationship, and the register is where you can see that the relationship exists. If you want the fuller picture of who may walk through your door and what each credential is trained to do, that’s here: who works with my child.

5. Three questions worth asking when the hours change

Hours move — up at the start, down at reauthorisation, sideways when staff leave. These three get a real answer, and none of them requires you to know any ABA:

  1. “How many hours were authorised this period, and how many were actually delivered?” A provider tracking its own work can answer this from a record, not from memory.
  2. “How much supervision did my child’s RBT receive last month, against how many service hours?” The board’s floor is 5%. The question is answerable, and asking it’s ordinary.
  3. “When did a supervisor last watch a session with my child, and what changed afterwards?” Supervision that never involves watching the actual work, and never changes anything, is a form on a shelf.

If the hours dropped because of a payer decision rather than a clinical one, ask which it was. Those two answers lead to completely different next steps, and providers can usually tell you plainly.
