- Will suit internationally mobile or globally minded families seeking a London senior school built around the IB rather than around GCSEs and A levels.
Admissions
Admissions at Southbank International School Westminster are internationally focused and clearly curriculum led, with the Westminster campus likely to appeal to families who want London-based continuity through the Middle Years Programme and IB Diploma rather than a GCSE-and-A-level pathway. It should suit globally minded families and students who are comfortable in an international, urban, academically purposeful environment.
Scholarships
Scholarships are not the main story. Families choose Southbank Westminster for its full IB pathway, global community and university-facing outlook rather than for awards alone.

Inspection snapshot
The overall picture is distinctly international, with the Middle Years Programme and Diploma Programme doing most of the explanatory work rather than the conventions of a traditional English senior school. Parents should still visit because the decisive question is whether the IB culture, central London setting and student mix feel right in practice.
