The exam system in England is suffering from “deterioration and decay”, says a damning report from leading independent school head teachers.
Head teachers attacked huge variations in results and poor marking.
The most able pupils now have to “dumb down” their answers to get A* grades, said the leaders of the Headmasters’ and Headmistresses’ Conference.
Christopher Ray, the independent schools group’s chairman, said the exam system was in a “truly shocking” state.
This summer has seen angry protests from head teachers over what they claimed were unfair changes to GCSE grade boundaries.
And the HMC – representing 250 of some of the most famous independent schools – has launched its own broadside against the exams system, in a report that says there are deep-rooted problems with unreliable, unfair and inaccurate marking.
