GCSE results (2024/2025)
186 pupils at the end of key stage 4 in 2024/2025
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.
A-level results (2024/2025)
Source: DfE performance tables 2024/2025. “Suppressed” means the DfE withholds figures for very small cohorts.
Attendance (2025/26 autumn term)
Autumn-term absence, DfE pupil absence data. Lower is better.
Staffing
Full-time-equivalent, 2025/26.

80% of teachers stayed at the school the following year · 6% moved to another state school · 14% left the state-funded sector
School Workforce Census, DfE. The ratio counts full-time-equivalent qualified teachers; retention follows teachers in post one November to the next. Open Government Licence v3.0.
