Ofsted

Inspected under the current framework, which gives no overall grade, on 19 November 2024.

Inspections since September 2024 do not give an overall grade, so there is no one-word judgement to report. The full report sets out what inspectors found.

GCSE results 2024/25

Attainment 8 score

61.8 England 47

The average grade across eight GCSEs, doubling English and maths. 50 is roughly a grade 5 average.

On Attainment 8 this school is in the top 10% of state-funded secondaries in England.

Compared with the fifth of schools whose intake is least disadvantaged, which is where this one sits, it is in the better-performing half.

Progress 8 2023/24

0.67confidence interval 0.43 to 0.91

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

47% 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
90%

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.
