What the school inspection says

“Pupils enjoy attending this school ... Leaders have high expectations for pupils’ conduct. They seek to develop inquiring, informed and compassionate young leaders … Leaders have carefully considered all their pupils when developing the extracurricular programme. Opportunities range from sport and music activities [to] jewellery club and the ‘zen den’, which takes place every lunchtime to provide a quiet space for pupils ... Sixth-form students have been trained as mental health ambassadors ... The school has recently been re-accredited with the National Equalities and Careers Award.”

*Ofsted no longer makes an overall effectiveness judgment in inspections of state-funded schools. A five-point grading scale, including a new “exceptional” grade was introduced in November 2025.
