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.

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.

Through a commitment to academic excellence and a uniquely liberal ethos, the IB also develops students with an inner belief in themselves. Southbank students have an openness to the outside world and a desire to give back to communities on a local, national and global level.

IB Diploma Results at a Glance

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.

 

These outcomes place Southbank among the leading IB schools globally. Just as importantly, they reflect the strength of our inclusive, student-centred approach – where academic achievement is balanced with critical thinking, creativity, and global awareness.

 

We congratulate all our students and thank our dedicated teachers, staff, and families for their continued support.

    Huge congratulations to our Head of Creative Arts, Mr Brendan Linnane, who completed the 2-mile Swim Serpentine last weekend, the final stage of the London Classics challenge! 

This incredible journey has included the London Marathon (run in support of Age UK Westminster) and RideLondon 100, and now this final swim is raising funds for Whisper, a volunteer-run charity supporting a children’s hospital, maternity unit, ambulance service and nursing school in Uganda.

Mr Linnane says he’s grateful for the support from Southbank students, parents, and colleagues — and hopes his journey inspires others to set goals, stay focused, and use personal challenges as a way to make a difference.
