Cranbrook School is a co-educational Kent grammar school with an identity that is older and broader than the modern 11-plus system. Founded in 1518, it combines selective day places with boarding from Year 9 and has a current roll of about 918. The school has a Christian character and a small-town setting, but its boarding houses and sixth form give it a wider reach than many Kent grammars.
The academic offer is framed around high expectations and a strong personal-development programme. Cranbrook's sixth form is about 300 students and uses a dedicated two-storey Sixth Form Centre, with supervised study spaces, a group-work area and a social zone. The A-level programme includes structured teaching and supervised study, while enrichment can include the EPQ, Sports Leaders, first aid, peer mentoring, finance, careers research and presentation skills.
Boarding is part of the school's texture rather than an add-on. Official boarding material describes small houses, evening prep, shared meals and weekend activities, with boarders joining the same lessons, teams, music, sport, drama, CCF and Duke of Edinburgh opportunities as day pupils. Named facilities include boarding houses, performance spaces and the sixth-form centre.
For Year 7 day entry, Cranbrook has a published admission number of 90 and uses the Kent Test. Children must be assessed suitable for grammar school, then the school's priority-area and oversubscription rules apply, including looked-after, pupil-premium, social or medical, sibling and staff-child criteria before score and distance rules. Recent official benchmarks show Ofsted Good, 93.5% grade 5+ in English and maths and 21.7% AAB or better at A level.
