About

A very warm welcome to Dr Challoner's High School. We are here to provide the best possible education for girls. We are passionate about the breadth of aspiration and opportunity , and ensure that our girls are empowered with the skills, habits and attributes needed to thrive in the 21st Century and to contribute significantly to the world.

A leading selective grammar school for girls, Challoner's High has a strong tradition of academic excellence, consistently placing in the top 30 in state school examination league tables and top in Bucks for academic progress (value added). Judged by Ofsted as Outstanding , we subsequently became only the ninth school in the country to gain the Exceptional Schools Award.

Nearly all of our students choose to go to university, with most going to Russell Group institutions, including Oxford and Cambridge.

In the school’s own words, from the school website.

Governing body (24 current, 5 former)

iAcademy trust: local governing body and trust board.

21 governors are linked to a profile (all confirmed).

Governors marked “Confirmed same person” have exactly the same forename and surname as the only officer of that name at the school’s own academy trust company on the Companies House register, so we treat them as the same person. The governance record itself comes from DfE.
