Wrenn School in Wellingborough has recorded its best ever GCSE results for the fourth year running.
A total of 75 per cent of pupils achieved at least five A* to C grades, and 58 per cent achieved five A* to C grades including maths and English.
Almost one fifth of the grades were A or A*, and nearly three-quarters were C or above.
A total of 30 pupils gained at least six A/A* grades, with eight students achieving 12 or more.
Among the high achieving pupils were Toby Ryman-Tubb, with 8 A* grades, Simon Howard-Clark and Danny Ash, who both got six A*s.
A school spokesman said: “In English, the school managed to buck the reported national trend of falling grades, while attainment in maths soared to new heights.
“Languages, humanities, art and music - along with other subjects - also had successful years.
“In 2011 the school’s improving GCSE results were in the top 10 per cent nationally. With a similar improvement in 2012 this is likely to be the case again.”
Headteacher William Thallon said: “We are really proud of the success our students have earned. Very well done to them, their families and their teachers.”
Danny Ash, 16, of Rushden, said: “I did a lot of revision, but it has paid off.”
