Mad-jock is correct. Numerous of the schools (at least out here) have non-examiners marking the papers - and the CAA have already been told.
I know of one place where the owners mother told me that I was not allowed to mark examination papers - only she and the owner were allowed to do them - oh, and the accountant did some, too.
That was despite the fact that I was the nominated custodian of the papers and the only authorised examiner in the company.
