The Latimer Arts College says 92 per cent of students gained five A* to C grades at GCSE.
The college also reported that 63 per cent of students achieved five A* to C grade GCSEs including English and maths (national average 58 per cent)
Eighty per cent of students achieved A*-C pass in science subjects while maths results reach a record high with 79 per cent of students achieving A* to C grades.
Principal Siobhan Hearne said: “I’m delighted to report that once again we have shown positive progress in our GCSE results and are thrilled to have exceeded national averages in all of our core subjects.
“The Latimer Arts College has seen a substantial increase in A* and A grades this year, with notable successes including students Milan Caska, Rose Edgeworth, Emily Sparkes, Katie Thomas, and Ben Watkin-Wynn, who collectively achieved a total of 53 A* to A grades.
“This has proved a challenging year for students across the country following government changes intended to make core GCSE exam marking harder.
“I would like to congratulate all of our students, many of whom are now returning to study A-Levels, and we look forward to welcoming visitors to The Latimer Arts College’s open evening on Wednesday, October 16.”
