Some schools were too focused on gaining C grades, because it is this measure which counts in league tables, when pupils had the capacity to achieve a A* or A grades, Sir Michael Wilshaw told the Sunday Telegraph.
I would like to see GCSE league tables reformed. The anxiety to get as many through those C boundaries have sometimes meant that schools haven’t pushed children beyond that.
We need sophisticated league tables which shows progress. Youngsters leaving primary school with level 5 should be getting A*, A or B at GCSE.
The report, which will take a representative sample of more than 50 secondary schools, will be published later this year.
