A refresher should not be a shorter replay of the original class. It should address the risk that has changed, the task that is drifting or the safety-critical behavior that workers need to perform reliably now.
Under 49 CFR 673.29, a covered transit agency must implement a comprehensive safety training program and include refresher training as necessary. The rule does not prescribe one calendar for every subject.
Use evidence to trigger the refresher
- A safety event or report reveals a recurring task error.
- A procedure, route, vehicle, tool, facility or emergency responsibility changes.
- Assessment shows that a critical skill is not performed consistently.
- A mitigation depends on behavior that has not been checked in the field.
- A worker returns after an extended absence.
These are instructional triggers, not automatic findings of fault. Training should not conceal an equipment, environment, staffing, supervision or procedure problem.
Build around one performance gap
- State the changed risk. Explain what is different and why it matters.
- Demonstrate the expected behavior. Use the real work setting when practical.
- Require practice. Let every learner perform and receive correction.
- Verify transfer. Score an observable result and plan a field check when warranted.
The FTA Fiscal Year 2026 Contractors' Manual directs reviewers to examine safety and refresher training. Oceans Transit's trigger matrix and four-part design are recommendations, not federal mandates.
Instructors should be able to say what the worker can now do, under what conditions, and how that performance was verified.
