Overview
Overview
Marymount International School brings together a Catholic, all-girls' education and a genuinely international community, with students drawn from more than 30 nationalities. The seven-acre garden campus supports both day and boarding life for pupils aged 11 to 18, and its position within reach of London adds museums, theatres, galleries and other cultural resources to the quieter rhythm of the grounds.
The academic route is built around the International Baccalaureate rather than a default GCSE-to-A-level sequence. The Middle Years Programme leads into the IB Diploma in Sixth Form, with inquiry, links between subjects, multilingual learning and independent thought running through the curriculum. Marymount was the first all-girls' school in the UK to adopt the IB, a piece of educational history that helps explain the confidence of its international model.
Residential life is available in full, weekly and flexi forms. Dedicated staff support a close boarding community, while clubs, sport, arts, leadership, trips and service learning connect students across the day. The campus provides a settled base, but boarding also makes purposeful use of London's cultural institutions, giving the school a distinctive balance of international outlook and place-based community.
Entry assessment changes with the point of entry. UK-based Grade 6 applicants attend an assessment day with aptitude testing, group activities and an interview; later MYP and IB Diploma applicants take written English and mathematics assessments and meet for an interview. The relevant standards were met, while the choice between day, flexi, weekly and full boarding remains part of the admissions decision.
