Welcome to the website of St Mary’s School Ascot, a leading Roman Catholic boarding school for girls aged between 11 and 18 years.
St Mary’s is a warm and caring community where we are passionate about bringing out the full potential of each of our 380 pupils. As a full boarding school, with only a few places for day pupils who live nearby, we offer a wealth of co-curricular opportunities, meaning that life at St Mary’s is vibrant, exciting and always good fun. We are proud of the strength of our academic achievements and work tirelessly to build on our tradition of excellence both in and out of the classroom.
We are a 45 minute journey from London, and are set in 55 acres of beautiful grounds. We would be very pleased to welcome you to St Mary’s at one of our Open Days, to show you our school and to introduce you to some of our pupils. In the meantime, we hope this website will give you a flavour of life at St Mary’s and the excellent opportunities and facilities we offer.

We are a Catholic school.

The Chapel is at the heart of our community, the place where we come together for prayer and worship, to share experiences, celebrate achievements, and provide guidance and support for each other. We encourage our girls in their spiritual relationship with God, and through this to embody those qualities valued by our founder, Mary Ward: freedom of spirit, sincerity and a cheerful disposition.

We are a girls' school.

Our pupils thrive in this environment, where they are able to pursue academic subjects and other activities according to their own talents and dispositions. They form life-long friendships, and learn to be confident and valued in themselves. They embody the prediction of our founder, Mary Ward, that ‘Women in time will come to do much’.

We are a full boarding school.

We are a full boarding school. Ours is a community that nurtures and sustains our pupils not just during the working day, but when that day has ended, and through the weekends as well. It is a community in which every girl can find the friendships and the support that she needs, while also having the space and the opportunity to develop and grow. We are proud to watch them mature into independent young women of conscience and spirit.

St Marys Ascot - Small

We are a small school.

Our size allows us to provide the very best facilities, and a full range of subjects at A Level, taught by the very best subject specialists, but it also ensures that we remain a strong, compassionate and friendly community in which every girl is known and understood, her needs cared for, and her talents recognised, so that she can grow and flourish into the fulness of a rich and purposeful adulthood.

We are an academic school.

The girls work hard and cheerfully, supported by superb teaching and an excellent pastoral system. They take pride in the improvements they make, they enjoy intellectual challenges, and they are willing to take risks along the way. All of this enables our girls to achieve outstanding results in public examinations, and to go on to a range of top universities both at home and abroad.
