At a glance
Chesham Grammar School is a co-educational Buckinghamshire grammar school for ages 11 to 18, drawing pupils from Chesham, the Chilterns, South Bucks and nearby Hertfordshire. Its history is more distinctive than the name first suggests. The school opened in 1947 as Chesham Technical School with six boys, became a co-educational grammar school in the 1960s, and changed from Chesham High to Chesham Grammar School in 2010. That technical inheritance still shows in the school's own account of its continuing strength in creative, artistic and technical subjects.
The school describes its vision as everyone enjoying, achieving and belonging, with aspiration, kindness and respect as core values. The academic tone is high but not narrow: the school website highlights an outstanding, co-educational community of more than 1,300 students, strong examination outcomes and progression to first-choice universities, including Oxford and Cambridge. Sixth form is presented as a rigorous step up, with a broad range of A-level subjects and a strong emphasis on independent learning, service and contribution to school life.
Daily school life is organised around belonging as well as attainment. The headteacher's welcome and about pages put the house system close to the centre of school culture, and the news stream gives a useful sense of the range: House of Lords youth engagement, school productions, literary events, science activity and alumni sport all appear in recent school-published material. That makes Chesham feel less like a results-only grammar and more like a large, busy selective school with a broad catchment and a strong internal community.
Year 7 admission is through Buckinghamshire's Secondary Transfer Test. The published admission number is 186, and the test combines verbal skills, mathematical skills and non-verbal skills, weighted 50%, 25% and 25%; a score of 121 or above qualifies a child for grammar-school consideration. Chesham's policy then applies its oversubscription criteria, including looked-after children, pupil-premium categories, siblings, children of staff and catchment. Official benchmarks record Ofsted Outstanding, +0.84 Progress 8, 99.4% grade 5+ in English and maths, and 43.3% AAB or better at A level.
