WELCOME TO SOUTHBANK INTERNATIONAL SCHOOL

We are London’s leading International Baccalaureate (IB) School, offering a different approach to academic excellence for children aged 2*-18. At our Central London campuses in Hampstead, Kensington and Westminster, we nurture talent, celebrate individuality and develop curious, inquisitive and constantly challenging minds. Our students consistently achieve outstanding results and first-choice university offers.

INTERNATIONAL BACCALAUREATE AT SOUTHBANK

The International Baccalaureate (IB) program is enjoyed by both international learners and those who have not previously studied the IB, including children moving over from private primary or secondary schools. The IB aims to do more than other curricula. It builds students critical thinking skills, nurtures their curiosity and their ability to solve complex problems.

IB DIPLOMA RESULTS

We are proud to share the exceptional results of our graduating Class of 2025 in the International Baccalaureate Diploma Programme (IBDP). This year, 75 students completed the full Diploma. Their results reflect the hard work, intellectual ambition, and commitment that characterise a Southbank education.
