Well over 90 per cent of students at Bishop Stopford School achieved five or more A*-C grade GCSEs this year.
Staff said the results of boys and girls were both very pleasing.
Around 90 per cent of students achieved C grade and above in GCSE English and over 90 per cent in GCSE maths, and at least 84 per cent of students achieved five A*-C including English and maths.
Initial analysis suggests that the progress measure for this group of students will exceed that of last year.
In 2012, the school was placed in the top 100 schools nationally for the progress students made between Key Stage 2 results and their GCSEs.
Initial figures in 2013 suggest that 32 students gained 10 or more A* or As in their results, and at least 63 per cent of all grades achieved in the school were A*-B.
Many other students exceeded expectations, or achieved to their fullest potential, and are now able to embark upon the next stage of their education from a very solid foundation.
Headteacher Margaret Holman said: “Particularly given the concerns cited in the press regarding predicted turbulence in GCSE results, we are delighted with the excellent achievements of our students this summer. The results are, once again, a testament to the hard work and commitment shown by the teachers and students, particularly over the past two years.”
