Good (2022) — Ungraded inspection — “School remains Good” (previous grade confirmed, not re-graded)
This school has not yet been inspected under the report-card system introduced in November 2025. When it is, this section will show a grade for each area — Ofsted says the new grades do not map onto the old ones, so we do not predict them.
Inspected 29 June 2022, published 30 September 2022. Read the full Ofsted report
England has three coexisting inspection systems — how we translate them into one signal.
Exam results
| Measure | 2024/25 |

| Reaching the expected standard in reading, writing & maths | 76% |
| Reaching the higher standard | 11% |
“Not published (small cohort)” means the DfE suppressed the figure to protect small cohorts — it is not a zero.

First-choice demand varies year to year, and the school’s admission criteria — not demand — decide who is offered a place. Use this as a rough signal, never a prediction.
