The best of unstuffy girls’ schools. The fun, the frolics, the fearlessness and (crucially) the future-proofing all foment in the greenest of settings, where girls can enjoy being unselfconscious girls till they are ready to take on the world beyond those unobtrusive gates. A happy place, where ‘everyone feels they are smashing it’, as one mum put it

Entrance

Academically selective. Girls wanting to join years 7, 8 or 9 with a registered place will be invited to a taster day, ostensibly for them to experience the school and to meet their year group, but also for the school ‘to begin to get to know them’.

Exit

A handful leave after GCSEs in search of wider/vocational subject choices and/or boys: Marlborough seems to be number one destination. Incoming sixth formers make up numbers.

These figures tell you the average grade and average points that pupils achieved in their academic qualifications. A maximum of 60 points are available for a grade A* at A level.


Teaching & learning

Definitely academic but not a hothouse. Girls are taught in their classes to start with and set just for maths. A second modern language added in year 8 alongside critical thinking, Latin or classical civilisation and optional ancient Greek in year

Arts & extracurricular

Hard to know where to start, as art, drama and music all shine here. The laughter and creative buzz which was the backdrop to the GCSE drama devised pieces we saw in rehearsal – sensibly done in year 10 here – was infectious, and though the theatre


Sport

Tennis tennis tennis, as far as the eye could see in the summer term, with all 20 courts seemingly occupied and the air thick with the thwack of balls on rackets. The tennis academy has earned a good reputation and attracts promising players.


Boarders

First and foremost a boarding school, with just 20 per cent day girls, some of whom can’t wait to board. Unusually, boarding is horizontal, so girls move houses with their year group every year or two. All the boarding houses are dotted around the

Currently 20 per cent from overseas and no plans to increase this; no nation or language dominates. We found the girls unaffected and pretty happy with their lot: enjoyable lessons and sport, enough to do at weekends and only the faintest grumbles

Money matters

The VAT increase has not been imposed in full initially, but a relatively young school this size at just 350 girls has fewer resources to absorb or spread the increase for long. Some extracurricular activities are chargeable, as are learning support

What the school says

St Mary’s Calne is one of the UK’s leading boarding and day schools for girls, with a happy community of around 350 pupils (80 per cent boarding, 20 per cent day), including a very strong sixth form of over 120 students, and a well‑deserved reputation for academic excellence.

Located in the heart of the Wiltshire countryside, the school prides itself on instilling a love of learning and a ‘can‑do’ attitude among its students. Pupils have the opportunity to discover and nurture their own talents and passions, while also experiencing new and enriching opportunities.

Students are highly ambitious and achieve outstanding GCSE and A level results, opening doors to top universities in the UK and abroad, as well as exciting careers.

As a full boarding school, St Mary’s provides a genuinely caring environment where young people thrive. Boarding by year group fosters strong, lifelong friendships, creating a tight‑knit community where students flourish together and enjoy an incredible sense of unity.

Life in a boarding house is vibrant and enjoyable, offering a full weekend programme of activities. From trips to water parks, ice skating, themed food nights, and socials, there is something for everyone.

Opportunities in sport, music, art, and drama are plentiful, and the facilities are superb, including an excellent sports complex and full‑size astro, a theatre, an impressive sixth form centre, and an award-winning library overlooking the historic orchard.

The girls excel at sport, with the school represented at county level in several major sports and nationally in athletics, lacrosse, and horse riding. Everyone is encouraged to take part and have fun.

St Mary’s is renowned for its outstanding pastoral care, which is woven into the heart of school life. An advantage of a small boarding school community is that girls are known and cared for as individuals.

The school is dedicated to preparing pupils to be future‑ready, with the confidence to thrive in an ever‑changing world. Come and experience for yourself what makes St Mary’s exceptional.

A warm welcome from the entire team awaits you.

They are: biology, chemistry, physics, mathematics, further mathematics, geography, history, English literature and classical or modern languages. The % of pupils achieving AAB or higher may therefore decrease if many pupils have opted not to take two or more of the facilitating subjects mentioned.
