Nope, when I sign the course completion certificate I verify the logbook entries and our own training records.
For a course beyond PPL level the training has all to be done with us anyway. At PPL level we can accept previous log book hours direct from the logbook.
You know as well as I do that we know the experience of a PPL student from flying with them so Parker hours are no value and we know the penalties for them anyway.
So I can't understand the original posters question unless they are trying to catch out someone.
