Internationalday2021marymount 6 | Marymount International School London

Inspired by the charism of the RSHM, we proudly stand as the first all-girls’ school in the UK to adopt the International Baccalaureate curriculum which promotes independent and creative thought among subjects.

Our girls love to learn and learn to love in an inclusive environment that challenges and supports them.

Girls here are empowered to build their confidence, spirituality, leadership skills and sense of self. Who we are teaching is as important as what we are teaching. Whether innovating in our STEAM Hub, debating in class, dancing on the stage, or learning a new world language, they are encouraged to sharpen their critical thinking skills, collaborate with others, and celebrate our diverse community of over 40 different nationalities. Securing top university placements beyond Marymount, our graduates are global citizen prepared to make a difference in the world.

Our garden campus is located just twelve miles from central London. We invite you to visit so you can see and feel what makes Marymount such a distinctive place for girls and young women to learn and grow into their best selves.
