The school that inspired Harry Potter author JK Rowling and where she finessed her writing skills has been put into special measures because its English exam results are some of the worst in the country.
Miss Rowling, 48, got inspiration for some of her characters in hero wizard Harry's Hogwarts school from Wyedean School and Sixth Form Centre.
She was head girl at the school in the Forest of Dean, Gloucestershire, in 1982 and her mother Anne was a technician in the science department.
The author, whose Harry Potter books have sold more than 450million copies and been translated into 67 languages, left with three A-levels in English, French and German.
But Ofsted says some current teaching at the school - whose library is named after its most famous pupil - is weak because it is 'slow and uninteresting'.
Their report said: "Achievement is particularly low in English and the 2012 GCSE results in this subject placed the school in the bottom three per cent of schools nationally."
Head teacher Clive Pemberton blamed falling exam results for the move.
In a letter to parents he said: "The special measures decision was based on examination outcomes and the inspectors recognised that we had already put in a number of measures which should secure improvements.
"We know we need to make progress and this is going to be monitored very closely."
