St Mary's School Ascot is a leading Roman Catholic girls' boarding school set in 55 acres of beautiful grounds in the heart of Berkshire, and 45 minutes from London. We are a friendly, warm and caring community, proud of our strong academic, cultural and sporting achievements, and dedicated to bringing out the full potential of each of our 390 pupils. As a full boarding school, with spaces for a few day pupils who live nearby, we offer a wealth of co-curricular opportunities which take place in the evenings and throughout the weekends. 

About Us


St Mary’s is a Catholic school, founded by the Institute of the Blessed Virgin Mary in 1865, and in the spirit of the Institute’s founder, Mary Ward, who believed that ‘women in time will come to do much’. Chapel is at the heart of school life, led by our resident Chaplain and our Director of Liturgy and Ministry. Almost all our girls are Catholic. It is not necessary for staff to be Catholic, but they are expected to respect and support the school’s Catholic ethos. About 50% of current staff are Catholic.

All Girls

St Mary's allows girls to flourish in a single-sex environment where they make lifelong friendships with other girls, and learn both to lead and to serve others. They run academic societies, organise charity and fund-raising events, serve at the altar, become school prefects, and compete at the top level in sport and other national competitions. They also enjoy academic and social events with local boys' schools. We are fully committed to giving each girl every opportunity to succeed in whatever she may wish to do.


We are extremely proud of our girls, who achieve outstanding results in public examinations. They are supported in their ambitions for university and beyond by a caring and experienced Sixth Form team, and go on to take up places on competitive courses at a range of Russell Group universities, including Oxford and Cambridge, as well as other prestigious institutions around the world. These achievements are nurtured by our careful and bespoke approach to academic growth and pastoral care.

Full Boarding

The boarding principles and aims of the school are based firmly on the values of respect for each individual in the school community, regardless of ethnicity, culture, gender or disability. We believe in respect for self, and the right of everyone to develop spiritually, culturally, morally and socially. Our Heads of House and residential staff provide a caring home environment for the girls throughout the day and night, while teaching staff help to deliver a wide range of cultural, creative, social and other activities in the evenings and at weekends. Girls collaborate with others in their House in a huge variety of academic, sporting and other competitions, forming life-long friendships on their journeys through adolescence with us.

Pastoral Care

Being a relatively small school of 390 girls allows us to provide outstanding pastoral care. The Head of House is the most important adult in each girl’s life at school, but all staff share in the responsibility of caring for the girls. Every teacher is also a tutor to a small group of girls, who are further supported by their Year Co-ordinator, their Deputy Head of House, the residential and infirmary staff, their teachers, the senior team, and the School’s Independent Listener and Counsellors. All work together to look after the welfare of the girls, to support them, encourage them, and help them to grow into mature and responsible citizens of the world.
