Overview

St Margaret's Prep and St Mary's Calne form a connected education in Calne, with the prep school welcoming boys and girls from age 2 to 11 and the senior school educating girls through Sixth Form. The two schools retain their own stages and daily experiences, but share a campus and a route from the early years into senior education. St Mary's adds both day and full-boarding options for older pupils.

At St Mary's, academic life is built around curiosity, critical thinking and the idea of winning your own race. Pupils are encouraged to question assumptions, weigh evidence and develop independent study habits, with personal tutors providing weekly one-to-one support. Years 7 and 8 lead into the GCSE years and then Sixth Form, where most students take three A levels alongside lectures, research and preparation for life beyond school.

Boarding uses horizontal houses, grouping pupils by year rather than age-spanning houses. Day girls belong to the same community, while girls at St Margaret's Prep can use the Year 5 and 6 boarding route as an introduction to residential life. More than 100 clubs and societies range across music, drama, sport, equestrian activities, debating, coding and the Duke of Edinburgh's Award.

The prep curriculum combines English, mathematics and science with creative and practical work, and the shared setting gives younger pupils contact with the wider St Mary's community. The senior school then develops its own academic, pastoral and Sixth Form programmes. Families considering the group need to distinguish the co-educational prep route from the girls' senior and Sixth Form experience while recognising the continuity between them.
