I have been reading some of the training requirements and I will add what we do...

We have a 4 phase training program

1) Formal Classroom training

2) Demonstration phase

3) Exercise phase

4) Evaluation phase

All our trainees must safely complete all 4 phases before they can be certified and they cannot be certified until the evaluator has signed the form off saying that the trainee has passed his evaluation phase.

We then have a certification phase and we have the re-fresher phase when needed. And as everyone else we have our 3 year re-eval phase. We take safety and training very serious in our company and we are very fortunate to have upper management, including the CFO and CEO 100% behind the training and safety sections.
