You see your child's RBT every session. You know their name, their voice, the toys they bring. Your BCBA shows up less often — maybe once every couple of weeks — and yet their name is on the treatment plan, their hours appear on the insurance bill, and the decisions that shape your child's therapy are theirs to make.



So what exactly is a BCBA doing with those hours?

That's the question I want to answer directly — not as a job description, but as a translation. Here's what a week in your child's BCBA's work actually looks like, and what it means for your child's progress.

A BCBA designs your child's ABA programme, supervises the RBT who delivers it, reviews data to decide what's working and what isn't, and keeps you informed throughout. In a typical week, those four things — design, supervision, data review, and family communication — are what the BCBA hours on your insurance authorization are actually paying for.

The three things your BCBA owns in your child's care

1. Assessment and programme design

Before your child's first session, the BCBA conducts a functional assessment — observing your child, talking with you, and using standardised tools to map what skills your child has, which are emerging, and which behaviours are getting in the way of learning or daily life.¹

That assessment produces your child's treatment plan: a set of specific, measurable goals and the strategies the RBT will use to work toward them. The BCBA also writes the behaviour intervention plan — the written document that tells everyone on your child's team exactly how to respond to challenging behaviours and why.

This isn't a one-time document. The BCBA updates the programme as your child grows, drops targets that have been mastered, and adds new ones. A treatment plan that hasn't changed in six months is a red flag, not a sign of stability.

2. Supervising the RBT

The RBT who works with your child daily is trained and credentialed — but they work under a BCBA's clinical oversight. The Behaviour Analyst Certification Board requires BCBAs to provide a minimum of 5% supervision of RBT service hours, which in practice means regular in-person observations, feedback sessions, and competency checks.²

When I observe a session, I'm not watching passively. I'm checking whether the RBT is implementing the programme correctly — are they using the right prompt level, reinforcing the right behaviours, responding to challenging behaviour according to the plan? If something's off, I correct it in the moment or debrief directly afterwards. For more on how the BCBA and RBT roles fit together, see our guide to BCBA supervision requirements.

3. Making the data mean something

Every session generates data. The RBT records how often a behaviour occurred, how many trials were completed, what percentage the child got correct. By itself, that's just numbers.

The BCBA's job is to turn those numbers into decisions. If a skill has been in the programme for three to four weeks and the data line isn't moving upward, that's not bad luck — it's a signal that the strategy needs to change. The BCBA looks at the graphs, identifies the pattern, and adjusts: a different prompt level, a different reinforcer, a different sequence.

That decision-making is what the clinical hours pay for — not the data collection itself, but the judgment about what the data means and what to do next.

A real week: what this looks like in practice

Here's what a typical week looks like for a BCBA managing your child's case. The specifics vary by family and setting — in-home, center-based, and school-based cases have different rhythms — but the core work is the same.



Monday — I pull up last week's session data for each child on my caseload. For one child, the tantrum data has been trending up since we changed the classroom schedule two weeks ago. I flag it and schedule a call with the family before the week is out.

Tuesday — I observe an in-home session. The RBT is implementing the reinforcement procedure correctly, but I notice the child is losing interest in the reinforcer we selected last month. I make a note to run a preference assessment at the next session and update the programme accordingly.

Wednesday — Supervision meeting with my RBT team. We go through cases together: what's working, what isn't, any behaviour we need to debrief. This is also where I answer clinical questions and make sure everyone is running the programmes consistently.

Thursday — A child whose data has been flat for four weeks on a mealtime goal. I spend time reviewing the session notes, re-reading the original assessment, and talking with the parents about what mealtimes actually look like at home. I decide to shift from a token board to a first-then visual and write the programme update for the RBT.

Friday — IEP meeting for a school-based child. I attend alongside the family, share the ABA data from the past quarter, and advocate for the accommodations and support hours that match what the data shows the child needs.

To see what ABA therapy at home looks like from the session level — what the RBT is actually doing during those hours — that post walks through a typical session in detail.

What BCBA hours actually pay for

Insurance authorises BCBA hours separately from RBT hours. For most cases, that's somewhere between 2 and 10 BCBA hours per week, depending on the child's age, intensity of need, and where they are in the programme.³

Those hours cover:

• The time spent reviewing session data and making programme decisions
• Direct supervision of the RBT, including in-person observations
• Assessment and programme writing
• Parent meetings and family coaching
• IEP meetings, school coordination, and communication with other providers

What they don't cover is the BCBA sitting in on every session. That's not how the model works, and it's not what most families need. What families need is a BCBA who is looking at the data every week, adjusting the plan when something isn't working, and communicating clearly when they do.

How to know your BCBA is doing a good job

These are the practical signals worth watching for:

You hear from them regularly. A BCBA who is actively managing your child's programme contacts you at minimum every two to four weeks — not just when there's a problem.

The programme gets updated. Goals that have been mastered get replaced. Strategies that aren't working get changed. A treatment plan that looks identical month over month isn't being managed — it's being maintained.

They share data with you. You should be able to see how your child is progressing toward each goal. If you don't know what the data shows, ask.

They observe sessions. A BCBA who never watches the RBT work with your child has no way to know whether the programme is being implemented correctly.

They show up when it matters. IEP meetings, transition planning, conversations with the school or paediatrician — these are moments when the BCBA's clinical knowledge is genuinely useful, and a good one makes themselves available for them.

When to raise a concern

You have the right to ask questions about your child's programme at any time. Raise a concern directly with your BCBA or the clinical director if:

• You haven't heard from your BCBA in more than four weeks
• Your child's goals haven't been updated in several months despite progress or stalling
• Data isn't being shared with you in a format you can understand
• The RBT mentions that the BCBA hasn't observed a session recently
• You have a significant concern about the programme and aren't getting a response

Raising these concerns is not difficult — it's appropriate. You are part of the clinical team.

How All Star ABA's BCBAs work with families

At All Star ABA, every child's programme is managed by a credentialed BCBA from day one. Our BCBAs conduct the initial assessment, design the treatment plan, supervise the RBT team, and stay in regular contact with families throughout the process — not just at quarterly reviews.

We provide in-home ABA therapy, center-based ABA therapy, and school-based ABA therapy across Maryland and Virginia, with no waitlist and most insurances accepted, including Medicaid.

If you want to understand what your child's BCBA will actually be doing — or if you have questions about a current programme — contact our team directly. We're glad to walk you through it.
