“That all may have life”
(John 10:10)
Welcome to Marymount International School London. We are delighted you are considering us for your daughter’s education, a responsibility and privilege we take very seriously.
Marymount is a Catholic, all-girls’ day and boarding school and the first all-girls’ school in the UK to adopt the International Baccalaureate (IB). We offer a challenging, internationally minded education, combining academic excellence with a commitment to educating the whole person.
Inspired by our founding Religious of the Sacred Heart of Mary (RSHM), we believe who our students become is as important as what they achieve. Small classes, exceptional pastoral care and extensive co-curricular opportunities nurture each girl’s talents, faith, leadership and sense of purpose.
Our diverse community and global network of RSHM schools encourage intercultural understanding and compassion. Every girl is known, valued and challenged, supported to achieve excellent academic outcomes and empowered to make a positive difference in the world.

Mrs Margaret Giblin
Headmistress
