ISI Report 2022 - Excellent

In 2022, St Mary's School received the highest grade of ‘excellent’ for our Independent Schools Inspectorate (ISI) inspection.

All independent schools in England are registered with the Department for Education (DfE) and are regulated directly by the Secretary of State for Education. The ISI is appointed by the DfE to scrutinize independent schools in England and inspectors visited St Mary’s in May 2022 to conduct a thorough evaluation.


The school achieved an outstanding overall 98% parental satisfaction rate.

'Almost all pupils achieve places at the most selective universities, conservatoires and art colleges in a range of disciplines, including those with the highest entry criteria.'
