The International Baccalaureate Diploma Programme
At Marymount International School London, the International Baccalaureate Diploma Programme (IBDP) is more than a qualification; it is a transformative educational experience that prepares students to excel at university, lead with confidence and make a meaningful impact in the world.
Recognised by leading universities across the globe, the IB Diploma challenges students to think critically, communicate effectively and engage with complex global issues. Through its unique combination of academic rigour, breadth of study and personal development, the programme equips students with the knowledge, skills and character to thrive in an ever-changing world.
What is the IB Diploma Programme
The IB Diploma Programme is a globally respected, pre-university course that encourages students to develop intellectually, emotionally and socially. Students study a broad range of subjects while developing the critical thinking, research and communication skills needed for university and beyond.
“IB students demonstrate significantly stronger critical-thinking skills than their non-IB peers”
– Professor Therese Hopfenbeck, University of Oxford Centre for Educational Assessment
