RBT Supervision Requirements: The 5% Rule Explained

1 The 5% rule, explained simply

The core BACB rule lives in the Ongoing Supervision section of the RBT Handbook, and it is exactly one sentence: you must obtain ongoing supervision for a minimum of 5% of the hours you spend providing behavior-analytic services each calendar month. Five percent is the floor, not the target, and your supervisor can require more. Here is what the floor looks like at typical caseloads:

Count only hours you spend providing behavior-analytic services, things like conducting preference assessments, implementing discrete-trial teaching procedures, and generating session notes. And keep the percentage straight in your head: it is 5% of your hours, not 5% of your month and not a flat number of hours per week. When your caseload changes, the minimum moves with it.

2 Who is allowed to supervise you

RBTs practice under the direction and close supervision of either an RBT Supervisor or an RBT Requirements Coordinator, who are responsible for all work the RBT performs. In practice: a BCBA may serve as an RBT Supervisor or an RBT Requirements Coordinator, and a BCaBA may serve as an RBT Supervisor. Supervisors who oversee the work of RBTs must also have completed the BACB 8-hour supervision training.

You may have noticed older guides mention a Responsible Certificant. That was the previous BACB term for the certificant responsible for all of an RBT work, and it has been replaced in current BACB materials by the RBT Supervisor and RBT Requirements Coordinator titles. The meaning did not change: one qualified certificant is on the hook for the quality and safety of everything you do with clients, which is why the supervision rules carry real consequences.

Two administrative details matter more than they look. First, your supervisor must add you as a supervisee in their BACB portal account. Second, the public BACB Certificant Registry shows your supervisor and your certification status, so employers, funders, and families can verify you in about ten seconds. Newly certified RBTs appear on the registry within approximately 24 hours of passing the examination.

3 The two-contact rule (this is where most people slip)

The percentage is not the whole structure. Supervision must include at least two face-to-face, real-time contacts per month. Phone calls and emails do not count. Your supervisor must observe you providing services in at least one of the monthly meetings.

In-person, on-site observation is preferred by the BACB, but the rules allow video cameras, video-conferencing, or similar means instead of the supervisor being physically present. Internet-based supervision has to comply with all applicable laws, and video monitoring on its own, without real-time interaction or feedback, may not count as supervision. One observation per month is the minimum; the BACB encourages direct observation of service delivery as much as possible.

4 Supervision starts before day one, not after 60 days

Some older blog posts float a "first 60 days" concept for RBT supervision. The current RBT Handbook contains no special first-60-days supervision rule. What it does require is stricter in a way: your RBT Supervisor or RBT Requirements Coordinator must add you as a supervisee in their BACB portal account before you begin services. The monthly 5% and two-contact structure applies from your first month on the job.

If you are preparing for certification, this is why employment usually comes before the exam application. RBT certification was designed for settings where a BCBA or BCaBA is already providing services, and most candidates complete training and the competency assessment through the organization where they will keep working under that organization supervisor.
