Djanogly City Academy in Nottingham has bucked the national trend and achieved a big rise in the proportion of pupils getting top GCSE marks.
It is a big relief to the inner city school which was under pressure from the Government to improve.
In February the Department for Education sent the Academy a pre-warning letter following years of poor performance. It threatened the school with the possibility of the Government stepping in and imposing a new sponsor to take charge.
This morning however the school achieved its best ever set of results with 43% of students gaining 5 A-C grades including English and Maths - up from 34% last year.
Head teacher Andy Kilpatrick said he was delighted in what had been an exceptionally tough year, with harsher marking and shifted grade boundaries.
