Our School

A Brief History of Southbank

In 1979, Milton Toubkin, David Tucker, John Marberry, Susan Marberry and Stephen Bailey signed a document establishing the American International School (AIS) with three key principles:

  1. The school would be democratic
  2. The school would use London as the classroom
  3. The curriculum would be individual

In 1981, the school moved into a Victorian primary school building on Cornwall Road and was renamed Southbank International School. Southbank was the first school in the UK to be authorised to offer all three International Baccalaureate (IB) programmes in 1997.

The school has flourished from its humble beginnings on London’s South Bank with a few dozen students to a tri-campus institution in the heart of London serving more than 700 students ranging from ages 3-19 years old.

Southbank International School has led the way in providing internationally-relevant world class education for more than 30 years and continues to be at the forefront.


Southbank is authorised (and regularly evaluated) by the IB and is also inspected by the Schools Inspection Service (SIS). Southbank is a founder member of the International Baccalaureate Schools and Colleges Association of the UK and Ireland (IBSCA), and the London International Schools Association (LISA) and a member of the International Schools Sports Association (ISSA) and Independent Schools Associations (ISA).
