Ofqual: English GCSEs will not be regraded

England's exams regulator, Ofqual, has refused to order exam boards to regrade this summer's English GCSE in a row over this year's results.

Head teachers had urged Ofqual to investigate when it was revealed that grade boundaries for the exams were changed part way through the year.

Ofqual's chief executive said it had looked carefully at how the exam boards had managed the awarding of all GCSE qualifications this year.

Glenys Stacey said examiners acted properly, and set the boundaries using their best professional judgement, taking into account all of the evidence available to them.
