I agree with Pathtrainer,s pass fail concept. The evaluation is a simple pass/ fail of the tasks the operator will have to complete in the workplace.
In fact, my experence is most evaluations of experence drivers can be performed while they work ( e.g. loading a trailer).
Some trainers use a score card totaling up the final score as the result. The idea of a point system realy dosen't work out unless its custom written to the work enviroment it will be used in.
Simple pass/ fail is best.
