We're having a little debate over how effectiveness of training is documented. Without question, each individual's records must show his or her competence level. But for effectiveness of training, does this need to be documented on an individual basis? Or can it be looked at from a higer level. For example, if we train our procedure on nonconforming product to everyone involved in the handling and disposition of it, do we need to go back and inividually establish the training was effect with each person? Or can we, based on audit results, observations, etc., establish if the training was effective or not for the organization in general?
