Inside the three parts of Crown Woods College

A school in south-east London claims that splitting into three separate sections based on ability has improved exam results and behaviour.

Crown Woods College has almost 2,000 pupils, but is segregated into three different building complexes, each with its own head and teachers.

The idea is based on a model used in some schools in the US.
