Ewell Castle School

Epsom, Surrey, South East · KT17 2AW

Founded in 1926 and educating pupils from age two through to eighteen, Ewell Castle School in Epsom takes a notably small-class approach, with a pupil-to-teacher ratio of around six to one. The Independent Schools Inspectorate rated the school 'good' overall, and singled out personal development as 'excellent', with all compliance standards met. With about 640 pupils, it sits comfortably in the medium-size band and offers a broad spread of qualifications including GCSE, A-level, BTEC and the EPQ. A no-mobile-phone culture, using Yondr pouches for Years 7 to 11, signals a deliberate focus on attention and presence during the school day.

Teaching & academics

Headline results sit below national benchmarks: the Attainment 8 score of 39.5 trails the national average of 46.9, and the recorded figure for grade 5+ in English and Maths is unusually low and worth probing directly with the school. That said, 46% of GCSE entries reach grades 9-7, and at A-level a third of grades are A*-A with more than half at A*-B. Popular sixth-form choices span Psychology, Mathematics, History, Geography, Chemistry and Business Studies. Around 12% of pupils receive SEN support, and the very low class ratio points to a school built around individual attention.

The last word

A small-class, all-through independent that prizes personal development and a focused, phone-free day. Parents drawn to attentive teaching will want to weigh that against academic results that currently lag the national picture.
