Admissions
Admission to the school is brokered through Buckinghamshire County Council, which operates a selective secondary education system throughout the county. Pupils have to achieve a mark of 121 or above in the 11-plus to be eligible to attend the school. The school's catchment area broadly covers the whole of Chiltern District area which includes the towns of Amersham, Chalfont St Giles, Chalfont St Peter and Chesham, and larger villages such as Great Missenden and Little Chalfont. A significant proportion of the intake also comes from Hertfordshire. As Chesham Station is a terminus on the Metropolitan Line of the London Underground, pupils also travel in from North London. The school's progress profile showed that these pupils performed prior to 2013 at a comparatively similar level at GCSE and A level.
