The furious head teacher at Feltham Community College has leapt to defend her school after it was criticised for its poor exam results.

The college was named alongside Longford and Hounslow Manor last week as being among 638 low-performing schools which must improve their performance at GCSE level or face closure under Schools Secretary Ed Balls' National Challenge ultimatum. 

With just 25 per cent of pupils at Longford, 29 per cent at Feltham Community College (FCC) and 25 per cent at Hounslow Manor achieving five or more A-C grades, including English and maths, the schools must now work hard to reach the new 30 per cent target.

But FCC head teacher Gillian Smith said: "Feltham Community College has shown its capacity to improve by increasing five A*-C GCSEs from 18 per cent to 59 per cent over the last four years.

"Last summer 29 per cent of our students gained five A*-C GCSEs, including English and maths. We anticipate that this figure will be in the 30s this year and the 40s the next."

Both Longford Community, in Feltham, and Hounslow Manor, declined to comment on the criticism or explain how they will reach the new targets.
