Dr Challoner's High School
Dr Challoner's High School is a selective grammar school for girls. Entry is via the GL exam, and there is no interview stage. The school has a defined catchment area, with priority given to girls living in catchment who achieve the qualifying score in the Buckinghamshire Secondary Transfer Test.
For a bright, self-assured daughter who wants to commit to her work while still making the most of music, sport and everything else going on, Dr Challoner's High School is a school many families set their hearts on. It is a selective grammar for girls aged 11 to 18, sitting at the end of a tree-lined drive in Little Chalfont with leafy Buckinghamshire woodland visible from many classrooms. The school shares its roots with Dr Challoner's Grammar School, the separate boys' school in Amersham: the original foundation traces back to 1624, the girls were established on the Little Chalfont site in 1962, and the two have run as distinct schools ever since. This is the girls' high school, which is worth holding clearly in mind when you apply.
The Good Schools Guide describes a bold, confident grammar where the girls are expected to shape the world, and adds that it has no doubt many of them will. It is hugely oversubscribed. The Guide's writers met hard-working girls and year 13 guides with a laidback, assured confidence that belied their age. Music is a real strength, with around 250 girls learning an instrument and a spread of choirs, orchestras and ensembles, one choir shared with the Challoner's boys. Sport is one of the most improved areas in recent years, with netball still reigning supreme, and the pastoral team has grown markedly over the past decade.
Headteacher Alan Roe has led the school since 2015. The picture that emerges is of an ambitious place that still leaves a girl room to be herself, work hard, and enjoy the years she spends here.

How do you get a place at Dr Challoner's High School?
To be considered, a child first needs to reach the required standard in the Buckinghamshire secondary transfer test. If the school has more qualified girls than places, places go in this order: looked-after and previously looked-after girls who reach the standard; girls in the catchment area in receipt of Pupil Premium; a set number of reserved catchment places for Pupil Premium or looked-after girls reaching a lower standard; then all other girls who qualify, ranked by distance from the school. The catchment covers Amersham, Chesham, Great Missenden, Prestwood, Chalfont St Giles, Chalfont Common and Gerrards Cross.
What happens if my child is ill on 11+ test day at Dr Challoner's High School?
The test is run by Buckinghamshire Council, so this is handled by them, not the school. If your daughter attends a Buckinghamshire state primary, she sits the test in school once she is well. If she tests at a grammar school or central venue and cannot attend, the council offers one alternative date. You need to send evidence from an independent source, such as a GP or hospital letter, within three working days of the test. Extra time or a separate room can be arranged in advance through your child's headteacher.
