Dr Challoner's High School is a selective girls' grammar school in Little Chalfont, near Amersham, with a roll of about 1,358 including sixth formers. It is one of the best-known Buckinghamshire grammars, but the school is careful to describe success as more than examination performance: the curriculum is meant to be broad, challenging and full of opportunity, with girls able to choose subjects that suit both ambition and interest.
The main-school curriculum keeps breadth visible through modern languages, sciences, humanities, creative arts, design and technology, philosophy, religion and ethics, PSHE and PE. In the sixth form, most students take three A levels plus an EPQ, with some taking Further Mathematics or a fourth A level. The sixth-form programme also includes weekly PSHE, co-curricular activity, PE, volunteering or work experience, co-curricular studies, alumni-led Connections events and tailored Oxbridge and medical support.
School life has a recognisable Challoner's shape: house events, music, sport, drama, clubs, leadership and a sixth-form culture built around independence and confidence. The site record also points to a sports hall, performance spaces, art and design areas and a sixth-form centre, giving the school the infrastructure for both academic and creative work.
For Year 7 entry, the published admission number is 180. Girls sit the Buckinghamshire Secondary Transfer Test, made up of a verbal-skills paper and a mathematical/non-verbal-skills paper. Once qualified, places are shaped by the school's catchment, pupil-premium, care-experienced, staff-child, sibling, medical/social and distance rules; the latest applications record lists 658 applications and 188 offers. Recent official benchmarks show Ofsted Outstanding, Progress 8 of +1.11, 99.5% grade 5+ in English and maths and 40.7% AAB or better at A level.
