What the data says

The Department for Education has not published where The Portsmouth Grammar 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.

Chemistry is unusually popular at GCSE: 74% of the year group took it, against 23% of pupils across England.

A level grades average A-, well above the England average of B-; 48% of students achieved AAB or better including two facilitating subjects (England 18%). The largest A level subjects are Mathematics, Physics and Biology.

Most pupils take the three separate sciences: at least 74% sat Biology, Chemistry and Physics as individual GCSEs, compared with about 23% nationally.
