The Kingswood School in Corby, which is to become an academy next month, celebrated an overall 98 per cent pass rate among its A Level students.
It was placed in special measures last November but after a recent inspection, the school was praised for making outstanding improvements.
And today (August 15) all the hard work by students and staff paid off.
The school’s headteacher Scott Hudson said: “The results were in line with our expectations and there has been an improvement.
“Students and staff stayed focussed and we’re delighted with the results.”
Lilith Bateman, head of sixth form, said: “We’re so pleased with the results and the hard work by students and staff. There has been a lot of monitoring, tracking and communicating and it’s paid off.”
Gage Talbot, 18, gained an A* in maths, A grades in physics and English Literature and a B in further maths.
He said: “I plan to study maths at Birmingham University and I’m really pleased with my results.”
Michelle Mirkovic, 18, celebrated B grades in English literature and English language and business studies and a C grade in politics.
She is to study English and Amerian studies at the University of Sussex.
Michelle said: “I had a bit of a sleepless night but I’m really happy with my results.”
Shannon Carey, 18, gained A grades in English language and English literature and B in history and plans to study English at Birmingham University. She said: “I’m just relieved it’s all over.”
Rebecca Moulding, 18, who achieved a Distinction* in IT studies and A grades in English literature and English Language, will start studying at the University of South Wales next month.
She said: “I was slightly nervous about the results but they are better than I expected.”
