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:
- An assessment produces a recommendation — typically written by a board certified behavior analyst after observing your child and talking with you.
- The payer authorises some quantity of hours. That may match the recommendation, or it may not.
- The provider schedules what it can actually staff. Authorised hours and delivered hours aren’t the same number, and the gap between them is a fair question to ask.
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:
- At least two face-to-face, real-time contacts every month. The handbook states supervision “may not occur over the phone or via email”.
- At least one of those two must be individual — no other RBTs or trainees present. The second may be a small-group meeting of between 2 and 10 RBTs, and the handbook caps that group at 10 regardless of how many supervisors attend.
- The supervisor must observe the RBT providing services in at least one of the monthly meetings. In-person, on-site observation is preferred; video-conferencing is permitted instead.
- Watching a recording isn’t automatically supervision. In the board’s words, “video monitoring on its own, without real-time interaction or feedback, may not count as supervision.”
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 receives | That’s about | Supervision 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:
- The BACB Certificant Registry lists an RBT’s RBT Supervisor and/or RBT Requirements Coordinator alongside their certification status.
- If nobody is on record, or the certification is inactive for any other reason, the handbook says the registry marks it “with red text stating that you may not practice”.
“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:
- “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.
- “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.
- “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.
