GCSE row: 'Students deserve consistent grades'

England's exams regulator, Ofqual, will not be ordering exam boards to re-grade this summer's English GCSE, its review says.

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

The regulator said the January papers were marked too leniently, but stood by the new June grade boundaries.

Mike Griffiths, head teacher at Northampton School for Boys, said students deserve to have grades that are "consistent within the year group".
