Outside of covering all the contents of a training schedule and ACOP'S to the best of our ability we surely have to ask ourselves a couple of questions.
1 - Would I be happy working with this person myself ?
2- Can I be reasonably sure that this person and all the people working with him/her will be going home at night ?

If the answer to either question is NO then the question of the effectiveness of the training has been answered (imho) ;-)
