Exceptional results, but a place depends on the entrance test rather than where you live — worth a look only if you are planning to sit it.

- The DfE stopped publishing Oxbridge and Russell Group shares for individual schools after the 2022-23 performance tables (students who left in 2019/20). Top-third figures continue.
- Figures are percentages of all students who finished 16 to 18 study at the school, counting those who sustained a university place in the two years after leaving.
- Rankings use the average across years weighted by the number of students; a school needs at least 2 years and 50 students to be ranked. The top-third ranking uses the latest 3 years. Ranks are among state-funded schools and colleges.
- '<0.5%' means above zero but under half a percent. 'Suppressed' means 5 or fewer students.
