The International Baccalaureate Diploma Programme in London
At Marymount International School London, the International Baccalaureate Diploma Programme (IBDP) is at the heart of our Sixth Form. Over two years, students aged 16 to 18 work towards the IB Diploma, a qualification that prepares them to excel at university, lead with confidence and make a meaningful impact in the world.
Recognised by leading universities in the UK and around the globe, the IB Diploma challenges students to think critically, communicate effectively and engage with complex global issues. Alongside six subjects, every student completes the three elements of the IB core: Theory of Knowledge, the Extended Essay and CAS (Creativity, Activity, Service). This combination of academic rigour, breadth of study and personal development equips them with the knowledge, skills and character to thrive in an ever-changing world.
As an all-girls IB school in London,Surrey with both day and boarding places, we offer students from the UK and overseas a close-knit community in which to take on the IB Diploma.
What is the IB Diploma Programme?
The IB Diploma Programme is a globally respected, two-year pre-university course for students aged 16 to 19. It encourages students to develop intellectually, emotionally and socially, building the critical thinking, research and communication skills needed for university and beyond.
Alongside their subjects, every student completes the three elements of the IB core:
- Theory of Knowledge (TOK), a course that asks students to reflect on how we know what we know, and to question ideas across different subjects.
- The Extended Essay, an independent research project of up to 4,000 words on a topic of the student’s choosing, excellent preparation for university-level study.
- CAS (Creativity, Activity, Service), which encourages students to take part in the arts, sport and community service, developing interests and responsibilities beyond the classroom.
“IB students demonstrate significantly stronger critical-thinking skills than their non-IB peers”
– Professor Therese Hopfenbeck, University of Oxford Centre for Educational Assessment
