Our core purpose is to realise the full potential of every student in our community, and we achieve this through small class sizes, a rich and diverse curriculum, and an extraordinarily talented and dedicated teaching team. As a not-for-profit school, our focus is always on the quality of learning.

Absolutely wonderful. I urge every parent to go to the Open House and see for themselves why this school is THE best in London. Delighted with every aspect of the school – and knowing that our son will grow up to be an independent, and global minded world citizen, is the greatest thing of all.
