The RBT 5% Supervision Rule, Explained (with examples)

If you're an RBT (Registered Behavior Technician), the BACB requires you to receive ongoing supervision while you're providing behavior-analytic services. The headline number most people remember is 5% — but it's easy to get tripped up on what exactly that 5% is calculated from, and what counts as supervision in the first place.

What the 5% rule actually says

In plain English: in a given supervisory period (typically a calendar month), at least 5% of the hours you spend delivering behavior-analytic services must be supervised by a qualified supervisor (usually a BCBA or BCaBA).

Supervision % = supervision hours ÷ service-delivery hours × 100

So if you delivered 80 hours of ABA services in May, you need at least 4 hours of supervision that month (80 × 0.05 = 4).

Direct vs. indirect supervision

Not all supervision is created equal. The BACB requires at least one real-time observation of you working with a client during each supervisory period — that's the "direct" piece. The rest of your supervision hours can be a mix of:

• Direct (in-vivo or live video): your supervisor watches you work with a client in real time.
• Indirect: meetings, case review, feedback on data, group supervision, etc.

What does NOT count toward the 5%

• Time you spent without a client (drive time, documentation between sessions).
• Trainings that aren't tied to supervision of your direct work.
• Supervision provided by someone who isn't a qualified BACB supervisor.

A simple monthly workflow

1. Log every session of client service delivery — that's your denominator.
2. Log every supervision contact (direct + indirect) — that's your numerator.
3. At the end of the month, check: numerator ÷ denominator × 100 ≥ 5?
4. Confirm at least one of those supervision contacts was a live observation.

Doing this weekly (not monthly) is the single best way to avoid a scramble at month-end. If you're at week 3 with 60 service hours and only 1 hour of supervision, you know to schedule another supervision contact before the period closes.

How HoursNest tracks this

In HoursNest, log service-delivery hours under the "Worked" category and supervision under Direct or Indirect. The RBT dashboard card automatically computes your supervision % for the current period and warns you if you're trending under 5%.

See the companion guide: RBT Supervision Tracker — how to log hours and stay compliant.

The bottom line

The 5% rule isn't complicated, but it punishes anyone who tracks hours from memory. Pick one tool, log every session the day it happens, and check the percentage weekly. That's it.
