Ungraded inspection: no current grade
Ofsted's most recent visit was an ungraded inspection; its outcome was “Improved significantly”. Since September 2024 these outcomes no longer confirm a named grade, and the school's last graded inspection is too old to appear in Ofsted's current data file, so SchoolFacts shows no grade rather than guessing. Earlier grades are on the school's Ofsted report page.

Progress 8 is suspended nationally for 2024/25 and 2025/26. These cohorts sat no key stage 2 tests (COVID), so there is no baseline to measure progress from.

Attendance (2025/26 autumn term)
Autumn-term absence, DfE pupil absence data. Lower is better.

Spending per pupil
Total expenditure ÷ pupils, council-maintained school finance return (DfE Schools Financial Benchmarking, latest year). Higher spending is not a measure of quality. It often reflects greater pupil need or a smaller school. Open Government Licence v3.0.
