BCBA vs RBT: who does what in your child's ABA programme

Start reading about ABA in Dubai and the letters arrive quickly: BCBA, RBT, sometimes BCaBA, IBT or ABAT too. They are not interchangeable, and knowing what each means tells you a lot about how a programme will be run and who is accountable for it.

Two roles, one programme

Most ABA programmes are delivered by a team working at two levels. One person designs the programme and is responsible for it. Another delivers it, session by session. In the system many UAE providers use, those roles are the BCBA and the RBT, and both credentials are issued by the Behavior Analyst Certification Board (BACB), a US-based certification body.

Neither role is a lesser version of the other. A programme needs a clinician who can assess, analyse and decide, and it needs someone who can show up consistently, build a relationship with your child and deliver the plan the same way every time. Most of what a child experiences of ABA is the RBT. Most of what decides whether it is the right ABA is the BCBA.

What a BCBA does

A BCBA (Board Certified Behavior Analyst) holds a graduate degree, has completed a substantial period of supervised practice and has passed the BACB's certification exam. They maintain the certification through continuing education and are bound by the BACB's ethics code.

In a child's programme, the BCBA typically:

• Assesses your child: their current skills, what is getting in the way, and what matters most to your family
• Writes the programme, including the goals, how each one will be taught and how progress will be measured
• Works out why difficult behaviour is happening before deciding how to respond to it
• Trains and supervises the RBT, including watching sessions and giving feedback
• Reviews the data, decides when a target is mastered or needs rewriting, and changes the plan
• Coaches you, so the strategies carry on between sessions

Some programmes also involve a BCaBA (Board Certified Assistant Behavior Analyst), a level that requires an undergraduate degree and can take on part of this work, also under a BCBA's supervision.

What an RBT does

An RBT (Registered Behavior Technician) has completed a set training course, passed a competency assessment observed by a qualified supervisor, passed a background check and passed the BACB's RBT exam. The credential is designed for people who deliver ABA, not design it, and the BACB requires RBTs to practise under ongoing supervision.

Day to day, the RBT:

• Delivers sessions one-to-one, following the programme the BCBA has written
• Builds a relationship with your child, which is much of what makes sessions work
• Records data on each target, every session
• Notices what is changing and reports it, so the BCBA can adjust the plan
• Uses the agreed strategies for behaviour, consistently and calmly

What an RBT should not be doing is deciding the goals, inventing new strategies for serious behaviour, or running a programme with no supervisor behind them. That is not a criticism of RBTs. It is simply the role the credential was designed for.

You may also come across other entry-level credentials in the UAE, such as IBT or ABAT, issued by different boards. Our article on IBT, RBT and ABAT explains how they compare.

How supervision actually works

Supervision is not a BCBA glancing at a spreadsheet once a term. In a well-run programme, the BCBA observes sessions regularly, sometimes working alongside the RBT and sometimes checking how a particular target is being taught, and gives specific feedback. They read the session data, look for patterns, and change the programme when something has stalled or been mastered. They are also the person you can go to when something is worrying you.

Ask any provider how often the BCBA will see your child in person, how they review the data between visits, and who you contact if there is a problem between reviews. Our article on what clinical supervision means covers the wider principle.

Questions worth asking

• Who is the BCBA on my child's programme, and when will they meet my child?
• How often will the BCBA observe sessions, and will I hear what they saw?
• What experience does the RBT have with children of my child's age and needs?
• Who decides when goals change, and how will I hear about it?
• If the RBT is unwell or leaves, what happens to my child's sessions?

The BACB publishes a registry on its website where you can check the status of a BCBA, BCaBA or RBT by name. It is a reasonable thing to do, and a good provider will not be offended.

At Special Minds, a BCBA writes and reviews every programme, and an RBT delivers the sessions one-to-one under that supervision, at home or at your child's nursery or school. Data is taken every session, the programme is reviewed with you each month, and if the fit between your child and the RBT is wrong, we replace the RBT.
