What the data says
The Department for Education has not published where Gad's Hill School’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.
Most pupils take the three separate sciences: at least 97% sat Biology, Chemistry and Physics as individual GCSEs, compared with about 23% nationally.
71% 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.
Languages are a small part of the curriculum here: entries in Spanish add up to 14% of the year group, and 9% of pupils entered the full EBacc set of subjects (England 41%).
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).
