What the data says
The Department for Education has not published where Haileybury College’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 A-, well above the England average of B-; 33% of students achieved AAB or better including two facilitating subjects (England 18%). The largest A level subjects are Mathematics, Psychology and Economics.
Physical Education is unusually popular at GCSE: 29% of the year group took it, against 11% of pupils across England.
Languages are a small part of the curriculum here: entries in German add up to 5% of the year group, and 0% 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 Hertfordshire 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
