Academic Excellence

The IB at Southbank International School

The IB from Southbank International School is more than an education. It’s a grounding for the increasingly complex and demanding world we live in. A commitment to academic excellence and a uniquely liberal ethos. An inner belief and confidence carried for the rest of life - through university - through a career - into a lasting impact on the world.

About our School

Southbank International School is the first school in the UK authorised to offer all three International Baccalaureate programmes

For more than 40 years, we’ve been at the forefront of providing internationally relevant, world class education.

At Southbank, experiences aren't just for the weekend or the holidays. It’s built into every day of the academic exploration and discovery of Southbank students. We help our students develop as independent, confident, curious and lifelong learners who fulfil their academic potential and take the natural next step into the world’s best universities.

We encourage our students to think critically and always challenge assumptions; developing an inner confidence to follow their path through university and into later life.

We ensure our students have an openness to the outside world and are ready to see other points of view. These qualities help our students develop to broaden their minds while excelling in their academic studies.

Thanks to our exceptional teaching staff and the International Baccalaureate curriculum, we help children and young people to become inquisitive learners who love to broaden their minds, always think critically, and do not shy away from challenging assumptions.

 – Siobhan McGrath, Executive Principal
