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.

From a childhood dream to an NYU Tisch acceptance — one of our Grade 12 students is heading to New York City to study drama at one of the most prestigious performing arts schools in the world. 🎭✨
The road to Tisch was anything but easy: countless self-tapes, live auditions, and detailed applications. But with unwavering determination and the support of Southbank’s Future Guidance Team, she made it.
As she prepares to begin the next chapter of her journey in musical theatre, we couldn’t be prouder. Broadway or West End — she’s ready to shine.

Throwback to last year’s Ice Cream Social! We loved the sweet treats, smiling faces, and chance to connect.
A relaxed, family-friendly afternoon — where we enjoy a frozen treat, you can meet your PTA Grade Reps, connect with fellow families, and say a casual hello to some of our Southbank staff and leadership team.
We can’t wait to welcome the entire Southbank community — new and returning — to kick off the year together!
