What the data says
The Department for Education has not published where Cobham Hall’s Year 11 leavers went next (destination measures are not published for independent schools), so this page relies on the school’s results and subjects.
A level grades average C, below the England average of B-; 6% of students achieved AAB or better including two facilitating subjects (England 18%).
39% of pupils achieved grade 5 or above in both English and maths GCSE in 2025 (England 45%). Attainment 8 is not comparable for independent schools, which often enter pupils for IGCSEs that the Department for Education does not count.
Where pupils went after Year 11
Destinations of the 2023 Year 11 leavers, measured the following year: the share in a sustained place for at least two terms. Compared with all state-funded schools in Kent and England.
The Department for Education has not published destination figures for this school (new school, small cohort or not a state-funded school).
Where students went after sixth form
