About the school
Chesham Grammar School (CGS) is a co-educational selective grammar school for pupils aged 11 to 18, located on White Hill in Chesham, Buckinghamshire. With around 1,300 pupils, including over 400 in the sixth form, the school has a long-standing reputation for academic excellence and was rated "Outstanding" in all areas by Ofsted in 2025.
The school was founded in 1947 as Chesham Technical School, following the Education Act 1944, and over the decades evolved through several names before becoming Chesham Grammar School in 2010. It was awarded specialist Humanities College status in 2007 and became an academy in 2011, and is now a member of the Red Kite Schools Trust.
Chesham Grammar School offers a broad curriculum that balances classical academic subjects with creative pursuits, supported by a wide range of clubs and extracurricular activities. As part of The Buckinghamshire Grammar Schools (TBGS) consortium, it uses the Buckinghamshire Secondary Transfer Test (STT) to select pupils for Year 7. The school is consistently oversubscribed, which makes early, well-structured preparation valuable for families seeking a place.

Admissions information
The Chesham Grammar School entrance test is administered through the Buckinghamshire Secondary Transfer Test (STT) system. Here is everything you need to know about the admissions process and exam structure.
Chesham Grammar School is one of the 13 schools in The Buckinghamshire Grammar Schools (TBGS) consortium, all of which use the Buckinghamshire Secondary Transfer Test (STT). The exam board is GL Assessment and the test is administered by Buckinghamshire Council as part of its Coordinated Admissions Scheme. Entry is on the basis of academic ability.
The STT consists of two multiple-choice papers, each lasting approximately 45 to 60 minutes with a short break between them. One paper covers comprehension, technical English and verbal reasoning; the other covers maths, non-verbal reasoning and spatial reasoning. Scores are age-standardised and weighted 50% verbal and 25% each for numerical and non-verbal ability. The test is sat in September of Year 6, with the main test for September 2027 entry on Thursday 10 September 2026 and a practice test on Tuesday 8 September 2026.
Children at state-funded Buckinghamshire primary schools are entered for the STT automatically. Families whose children attend a primary school outside Buckinghamshire must register online during the registration window, which for 2027 entry opens at 10am on 1 May 2026 and closes at 3pm on Tuesday 2 June 2026. Families must also submit their Local Authority Common Application Form (CAF), naming the school, by 31st October.
STT results are released to parents in October 2026, ahead of the 31st October application deadline, with allocations made on National Offer Day on Monday 1 March 2027. A standardised score of 121 is the qualifying threshold for consideration; achieving it does not guarantee a place, as the school applies its oversubscription criteria where demand exceeds places.
Key admissions details
Chesham Grammar School has a Published Admission Number of 180 places for Year 7, with around 1,300 pupils on roll across the school. A number of places are set aside for children in receipt of the Pupil Premium who live in catchment, and the school is regularly oversubscribed, so a qualifying STT score combined with the school's admissions criteria determines who is offered a place.
Chesham Grammar School operates a catchment area broadly covering Chesham and the wider Chiltern area, including Amersham, Prestwood, Great Missenden, Little Chalfont, Chalfont St Giles, Chalfont St Peter and Gerrards Cross. Entry is based first on a qualifying STT score; where qualifying applicants exceed places, priority follows looked-after children, free school meals in catchment, siblings, catchment residence, and then straight-line distance from the school.
