Ofsted judgement
Confirmed by a short inspection, not a full one
Ofsted's most recent visit was a short inspection on 15 November 2023, where inspectors confirmed the school remains Good. 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.
