We just had our SQF audit two weeks ago. The subject of documenting OJT (on the job training) came up. Our environment is very technical (Flexography=Printing, Laminating, Slitting, Pouching for food products) so OJT is the overwhelming majority of what we provide. New employees are trained in a mentoring system until deemed competent. The auditor suggested that the verification of sufficient training be achieved simply by "observation". Upon deeming a employee competent to perform job duties on their own, prior to that first shift flying solo, they are to sign off on a bullet list heavily generalizing the processes of their job duties (again, the atmosphere is so technical it is essentially a trade in itself to run some machines proficiently) and then signed by the supervisor as well. Occasional, one would imagine that mistakes are made and with mistakes comes corrective actions. If the corrective action is human error and further training is required, the employee will be forced back into an addition period (to be determined) of mentoring. The end of this re-training will be verified by the same form there-by closing the loop with documentation on the retraining and corrective action response as well. All forms are kept in the employee's file.
