They're not cheating the system rather they are driving a legal coach and horses through the holes in the moderation process. It's not illegal it's just that the moderation process is seriously flawed: too flawed to give a level playing field to all schools. The sample size is too small for a statistically significant outcome and it's a nonsense that the teachers pick the sample. For a proper moderation there should be a much larger sample which is picked by the moderator according to a formula which will guarantee a representative sample: ie candidatates drawn from the top, bottom, 75th, 50th and 25th percentiles of the ability range according to marks already achieved. A minimum sample size of 20 with a sliding scale for larger cohorts would be somewhere near right. I have also been moderated by moderators who do not understand the moderation process and do not follow the guidelines issued to moderators by the board. I've never reported them because their lack of rigour has always worked to the advantage of my candidates. I also know that the board will simply close ranks and not admit anything because they are scared stiff of any publicity which will call the board or the system into question. The Daily Mail and it's ilk are waiting to pounce; they would love a juicy story about how stupid drama exams are, especially in the current climate. Leave well alone I say. Try to get hold of a copy of 'Guidelines for moderators' ; it's issued to all moderators. You can check if your moderator follows them - many don't. I'll give you another dodge. Do 5 pieces of coursework; give your best candidates their best marks for piece 4. Enter piece 5 for the moderation and slightly undermark. If the moderator agrees the centre's marks then the marks for piece 4 are the marks that count towards the final total. You might even be lucky and get the moderator to raise all your marks then all your candidates benefit. If it's any consolation the Edexcel system of moderation is even more arbitrary and even more of a statistical nonsense.
