About this school

Ofsted judgement
Confirmed by a short inspection, not a full one
Ofsted's most recent visit was a short inspection on 25 April 2024, where inspectors confirmed the school remains Outstanding, but had some concerns; a full inspection will follow. The school's last full inspection took place before September 2019, so its area grades are not part of Ofsted's current published data. Older reports are on the school's Ofsted page.
