RBT PDU calculator
What is the best way to track RBT PDUs?
The most reliable way to track RBT PDUs is to work backwards from your recertification date: record your cycle start, the total units required, and every unit as you earn it, then divide the remaining units by the months left to get a monthly pace. RBTs certifying or recertifying from 1 January 2026 must complete 12 professional development units in each 2-year recertification cycle.

RBT recertification cycle (2 years) — 12 professional development units, required for RBTs certifying or recertifying from 1 January 2026
RBTs may start earning PDUs after they certify or recertify in 2026, so a cycle that began earlier may differ. In-service PDUs are awarded in 0.5 increments — 0.5 for 25 minutes of instruction, 1 for 50 minutes — and are never rounded up. Confirm your own cycle in the RBT Handbook.

How it is calculated
A recertification cycle runs two years from your certification or most recent recertification date.
In-service PDUs are awarded in half-unit increments — 0.5 for 25 minutes of instruction and 1.0 for 50 minutes — and partial time is never rounded up.
The calculator subtracts what you have earned from what you need, counts the days left in the cycle, and converts the shortfall into a per-month pace so the deadline never arrives as a surprise.
monthly pace = (units required − units earned) ÷ months remaining in the cycle
Worked example
- An RBT recertifies on 1 March 2026, so the cycle ends 1 March 2028.
- 12 units are required; 4 have been earned by 1 September 2026.
- 8 units remain with about 18 months left.
- 8 ÷ 18 = 0.44.
Result: About 0.5 units per month keeps the cycle on schedule.
