Independent secondary school in London, Kensington and Chelsea
Collingham
23 Collingham Gardens, London, SW5 0HL
Ofsted
Ofsted has not published an inspection outcome for this school.
This is usual for schools that have opened recently, and for most independent schools, which are inspected by ISI or another approved body rather than Ofsted.
Exam results
Independent schools are not comparable in the performance tables. Most enter pupils for international GCSEs, which are not approved qualifications for these measures, so any Attainment 8 figure would be calculated from a fraction of what pupils actually sit. We do not publish one rather than publish a misleading number.
- Average A level grade (2024/25)
- C+
A level entries are recorded consistently across school types, so this figure is shown.

Free school meals, English as an additional language and SEN figures come from the state school census, which independent schools do not report into. Their records return structural zeros rather than measurements, so they are not shown here.
