Six months ago a candidate told me that he was allowed to cheat in a controlled assessment in German. He was allowed to read from a sheet which should have been learnt. I asked my HOD about it, she was annoyed that the boy had told me, and annoyed with me as I asked her when a class was present. She told me that she allowed him to read it as he hadn't revised, and that she would put in a note to the moderator. However, I believe that this did not happen, as he had a high mark for speaking. I think he was allowed to do this as he is an eFSM pupil, and a target was to increase a-cs for eFSM pupils. If I report it now, my life in school will be a misery as my HOD is very chummy with SMT. Should I leave it? What would you do?
