BCBA Supervision Calculator

Under BACB requirements, each RBT must be supervised for at least 5% of the hours they spend providing behavior-analytic services in a calendar month. For example, if an RBT provides 120 hours of service across all clients, they need at least 6 hours of supervision that month.

At least 0.5 hours (30 minutes). The BACB minimum is 5% of the RBT’s service hours in a calendar month, so 10 hours of treatment needs 0.5 hours of supervision, 40 hours needs 2 hours, and 100 hours needs 5 hours.

The BACB requires at least two face-to-face supervision contacts in each calendar month, and at least one of them must be an individual meeting. Those contacts count toward the 5% minimum. Check the BACB RBT handbook for the full rules on format and documentation.

Take the total hours the RBT worked with each client that month and multiply by 0.05 (5%). Sum these across all clients to get the RBT’s total. The BACB counts 5% of the RBT’s total monthly service hours; the per-client breakdown is a planning aid, and some payers set their own per-client supervision rules.

Yes. BCBAs typically supervise multiple RBTs. Each RBT’s supervision requirement is calculated independently based on their own direct service hours. Use this calculator to track requirements across your entire caseload.

Since January 1, 2026, new RBT applicants complete a 40-hour training under the 2026 curriculum, taught by active BCBAs or BCaBAs who have completed an 8-hour supervision training. RBTs also move to a 2-year recertification cycle with 12 professional development units. The 5% monthly supervision requirement did not change.

CPT revises the ABA codes 97151 to 97158 and adds new codes effective January 1, 2027 (AMA; ABA Coding Coalition). 97155 becomes direction of the technician and analysis by the BCBA, and treatment the BCBA delivers directly moves to new code 97173. BACB supervision rules are separate from billing codes; check each payer’s 2027 guidance.
