There is no doubt that the standard in English which the current modular system of GCSE exams produces, falls short of what many young people need to get a good, or indeed any, job, unless they achieve the top grades. This is why Michael Gove is changing the system. Quite separately there is the question of whether all the marking this summer was fair to all the students. Manifestly it was not and something constructive is required to put things right in England.
Ofqual has conducted an enquiry and reached the surprising conclusion that the fault lies with over marking by teachers of coursework. It is clearly a ridiculous system where teachers mark their own pupils, but the integrity of the exam is supposed to be protected by monitoring of these markings by the exam boards. The job of Ofqual is to monitor the exam boards. When things go pear shaped, the buck stops with Ofqual.
This is why this blog finds the ice cold explanations of the chief executive of this ineffectual quango wholly unconvincing.
