In general, there's a training and qualification document that's been put together for use on the east coast. It identifies all the different types of training for all the different types of positions. Those are minimum requirements. The companies themselves will have a look at them, and they'll adopt those plus have internal training as well. That document is a living document and is continually reviewed and revised to drive up the standards for training and competencies.
