They will say that between January and June 2012 it was decided that too many students were going to get a C grade or better in GCSE English, so a decision was taken to push up grade boundaries for the exams marked in June to bring down the numbers of good grades for the year as a whole.
The state gives extra money to schools that get an A or improve their grade, and children at schools that get two F grades in four years are allowed to transfer to better schools.
