What the data says
Of the 177 pupils who finished Year 11 at Tonbridge Grammar School in 2023, 91% stayed on in Tonbridge Grammar School’s own sixth form (Kent average 56%), 2% went to a further education college and none started an apprenticeship.
Among the 118 students who left the sixth form in 2023, 69% went to university (Kent 39%, England 37%), and 73% of level 3 students progressed to one of the most selective universities, against 19% nationally.
GCSE results in 2025 were well above the national picture: Attainment 8 of 77.2 against 46.1 across England and 46.7 in Kent, with 98% of pupils getting grade 5 or above in both English and maths (England 45%) — as a selective grammar school, Tonbridge Grammar School admits pupils by test at 11, which drives these figures.
Music is unusually popular at GCSE: 25% of the year group took it, against 5% of pupils across England.
