Areas for Improvement
- Teachers do not consistently check pupils' understanding in lessons, meaning misconceptions are not addressed and gaps in knowledge go unnoticed
- Achievement gap between disadvantaged pupils and their peers remains too wide, with lessons not effectively adapted to meet their specific needs
- High suspension rates due to pupil behaviour, with new behaviour strategies not applied consistently by all staff
- Persistently high absence rates, particularly among disadvantaged pupils and those with SEND, causing them to miss vital learning
- New systems and processes are not consistently applied or understood by all staff, slowing improvements across the school
Safeguarding
Safeguarding arrangements are effective.
Extracurricular Activities
Sports, gardening, chess, music, Winter Concert, Duke of Edinburgh's Award scheme, school committees organising events
