How many RBT supervision hours per month
There is no fixed monthly hour count: an RBT must receive supervision equal to at least 5% of the hours they spend delivering behavior-analytic services that month, which works out to roughly 1 hour for a 20-hour month, 2 hours for a 40-hour month and 8 hours for a 160-hour month.

The requirement scales with the work. A part-time RBT and a full-time RBT do not owe the same number of supervision hours, which is why a fixed monthly target set once at hire tends to be wrong for most of the year.
Monthly targets by service hours
| Service hours in the period | Minimum supervision at 5% | Typical schedule |
|---|---|---|
| 20 hours | 1.0 hour | Two 30-minute contacts, one with a client |
| 40 hours | 2.0 hours | Two 1-hour contacts, one with a client |
| 60 hours | 3.0 hours | Weekly 45-minute contacts |
| 80 hours | 4.0 hours | Weekly 1-hour contacts |
| 120 hours | 6.0 hours | Weekly 1.5-hour contacts |
| 160 hours | 8.0 hours | Weekly 2-hour contacts, or twice-weekly 1-hour |
Round up, not down. Service hours often land higher than planned, and a period that ends 6 minutes short of 5% is a period out of compliance.

This calculator performs arithmetic on the figures you enter. It does not determine compliance — confirm current requirements and how your hours qualify with the certifying body and your supervisor. Projections are estimates built from the pace you enter. Only supervision that actually happens and is recorded counts toward a monthly minimum.
Worked example
A month that grows mid-period
- Planned service hours: 72 → target 3.6 hours of supervision
- Two contacts delivered by the 15th: 2.0 hours
- A new client is added; actual service hours finish at 96
- Revised target: 4.8 hours — not 3.6
- Remaining need: 2.8 hours across the final two weeks
Hours are not the whole requirement
- At least one contact in the period must be individual supervision.
- At least one contact must include the supervisor observing the RBT with a client.
- Group supervision counts only up to a capped share of the total.
- Every contact needs documentation and both signatures to be demonstrable later.
Because service hours move during the period, recheck the target mid-month rather than at close. A supervisor who books to the plan instead of the actual will under-deliver in any month where the caseload grows.
Frequently asked questions
- How many hours of supervision does an RBT need per month?
- At least 5% of the hours the RBT spent delivering behavior-analytic services that supervisory period — about 1 hour for 20 service hours, 2 hours for 40, and 8 hours for 160.
- What if an RBT delivers no services in a month?
- With no service hours delivered, there are generally no supervision hours required for that period. Document the period as having no service delivery so the record shows why the percentage is absent.
- Is 5% a minimum or a target?
- It is a minimum. Many organizations schedule above 5% so that a canceled contact or an unplanned increase in service hours does not put the period out of compliance.
- Do supervision hours reset each month?
- Yes. Each supervisory period stands on its own; extra hours delivered in one period do not carry forward to cover a shortfall in the next.
How this works in Operation Optimize
Operation Optimize recalculates the target as service hours change.
- The 5% target updates continuously as hours are logged
- Mid-period alerts fire before a shortfall becomes unfixable
- Supervisors see which supervisees are behind, ranked by risk
