The King's School, Grantham is a selective boys' grammar school for ages 11 to 18 in Lincolnshire. It describes itself as modern and forward-looking while remaining close to the values on which it was re-endowed in 1528. The public values - courage, friendship, honour, humility, perseverance and responsibility - sit alongside a headmaster's message about a friendly, focused academic atmosphere where boys' interests and talents are recognised.
The academic offer is built around a long grammar-school tradition of high expectations. The school has a large sixth form of about 300 boys, with around 10% joining from other schools in Year 12, and it stresses induction into A-level study as well as the wider post-16 environment. Subject pages and the history curriculum material point to classrooms and resources shaped for specialist teaching rather than a generic secondary-school offer.
King's has a strong enrichment culture. The official enrichment page lists educational visits, fieldwork, language exchanges and visitors, alongside jazz ensembles, orchestras, choirs, bands and regular sport in rugby, cricket and football. It also names a flourishing Combined Cadet Force, Duke of Edinburgh, Young Enterprise, chess, quiz teams, language clubs, community service, fundraising and arts clubs. That breadth matters because it shows how the school develops character as well as examination performance.
Year 7 entry is through the Lincolnshire Consortium tests, with 174 places. Boys sit GL Assessment verbal reasoning and non-verbal reasoning/spatial awareness papers, and the same consortium tests can be taken only once in the school year. The stored admissions record notes a minimum standardised qualifying score of 220 and a 30-mile priority area before open score ranking. Official benchmarks record Ofsted Good, +1.10 Progress 8, 98.3% grade 5+ in English and maths, and 38.5% AAB or better at A level.
