On Attainment 8 this school is in the top quarter of state-funded secondaries in England.

Compared with the fifth of schools whose intake is middle, which is where this one sits, it is in the top quarter.

Progress 8 2023/24

0.64confidence interval 0.41 to 0.88

Taking that range into account, pupils made more progress than similar pupils nationally. DfE bands this as well above average.

Progress 8 measures how far pupils moved between the end of primary and their GCSEs, which makes it far fairer than raw attainment. It is shown for 2023/24 because it could not be calculated for 2024/25: that year group would have sat their key stage 2 tests in summer 2020, when the tests were cancelled, so there is no starting point to measure from. Every school in England is affected, not just this one.

Going on to university 2021/22 leavers

Went to a top third university

28% England 20.9%

The third of higher education providers whose entrants hold the highest average entry qualifications. It is the closest thing in the public data to "did they get into a competitive university", and it separates schools far more sharply than the headline progression rate does.

Went on to a degree
86%

England 65.3%

Students in the cohort

These follow an earlier group of leavers than the figures above, and count anyone reaching higher education within two years rather than the term after leaving, so they are not directly comparable with them.

A destination counts only if it lasted at least six months, which is why these figures lag the exam results by a year, and why the university figures track leavers from 2021/22. Small cohorts move these percentages a long way — check the cohort size before reading much into a gap.
