Founded in 1955 by the Religious of the Sacred Heart of Mary (RSHM), Marymount International School London is an independent school for girls, ages 11-18, nurturing the limitless potential of curious, creative young women of diverse faiths and backgrounds. We proudly stand as the ﬁrst all-girls’ school in the United Kingdom to adopt the International Baccalaureate curriculum (IB, MYP and Diploma), bringing together day and boarding students in a personal, dynamic, intellectually challenging, and supportive environment where multiple perspectives are respected and celebrated. We are part of a Global Network connected to other Marymount Schools in NY, CA, Rome and Paris to name a few.
The School is accredited by the Council of International Schools and the Middle States Association of Colleges and Schools. It is a member of the Independent Schools Council, European Council of International Schools, Girls’ Schools Association, Boarding Schools Association, and Catholic Independent Schools’ Conference. It is an International Baccalaureate World School authorised to participate in the International Baccalaureate Diploma and Middle Years programmes.
