# 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?

Save them into a free Professional Passport; renewal reminders build on the same dates.
