So the second test is basically is the grade awarded the correct band for the marks achieved?
I know that the exams have specific and prescriptive marking schemes. Are none of the remarks where someone checks an answer against a mark scheme and says that answer got say 11 out of 12 marks (clearly in accordance with the mark scheme) but only 2 marks have been awarded - there must have been an error? Does that fall within the first test you mentioned? Thanks.
The first check is what they call a clerical check, and the example you give would fall under that: have any mistakes been made in the process of marking the paper, either a 2 being written down when a 12 was given, or a mistake made in the adding up.
The second check is that the original examiner applied the mark scheme accurately to the paper. So if they gave a question 6 out of 10, can that mark be justified according to the marking criteria?
People still think papers are re-marked - they're not. We just check to ensure that the original examiner's marks can be objectively supported by the assessment criteria.
Grades are irrelevant to us, by the way: we work with numbers and the mark scheme. When I'm marking as an examiner, obviously the grade boundaries haven't yet been fixed for that session, and when I check scripts during the Enquiries About Results period, I never look at the grade boundaries for my paper. We're not looking for that extra two marks a student needs to get the next grade up, I'm afraid.
