Marymount International School London

Founded in 1955, Marymount International School was the first all-girls’ school in the UK to adopt the International Baccalaureate curriculum, offering the Middle Years Programme (MYP) for Grades 6–10 and the IB Diploma Programme (IBDP) for Grades 11–12. With day, weekly, and full boarding options, Marymount welcomes curious, motivated, and academically ambitious students from diverse cultural and faith backgrounds.

Our holistic and academically rigorous programmes foster critical thinking, collaboration, and global awareness. Small classes and a nurturing environment promote independence and intellectual growth. Marymount consistently achieves results well above the global IB average, ranking among the top 2% of IB schools worldwide. The school’s average IBDP score is 37, with over 30% of students attaining 40+ points. Graduates progress to leading universities in the UK, USA, and worldwide. Ideally situated on a secure 7-acre garden campus in south-west London, Marymount is just 20 minutes by train from Central London and 30 minutes by car from Heathrow and Gatwick airports.

Facilities include a STEAM Hub, Sports Hall, Dance Studio, tennis courts, and all-weather pitch. Boarding accommodation is modern and comfortable, with dedicated staff creating a warm, supportive home-from-home for international students.
