RBT assessment date calculator

When does my RBT competency assessment need to be completed?

Enter your 40-hour training completion date, competency assessment date and intended application date, and the calculator shows how they sit against the usual timing windows — training must be completed before the assessment, and the assessment and application must fall inside the windows the certifying body specifies. It is planning guidance; only the certifying body determines eligibility.

How it is calculated

Each date is checked against the sequence and the window that normally applies to it, and problems are flagged in plain language.

The timing rules are versioned and effective-dated, so results show which rule version they were calculated against.

Dates worth diarizing — such as the point at which an assessment would go stale before application — are listed as next actions.

Worked example

  1. 40-hour training completed 1 February 2026.
  2. Competency assessment scheduled 20 February 2026.
  3. Application planned for 15 August 2026.

Result: Sequence is valid, but the application sits near the far edge of the window after assessment — worth bringing forward.

Related questions

Does this confirm I am eligible?
No. It highlights timing that commonly causes problems. Only the certifying body determines eligibility.
Does the 40-hour training have to come before the assessment?
Yes. The training is completed first, and the competency assessment follows it.
Can a competency assessment expire before I apply?
The assessment must fall inside the window before application specified by the certifying body, so a long delay can force a reassessment.
What happens when the requirements change?
Results are stamped with the rule version they were calculated against, and the underlying rules are cross-checked against published sources.
Can I get reminded about these dates?
