Stamford School is a co-educational independent school in Stamford, Lincolnshire, educating pupils from age 2 to 18 across Nursery, Junior, Senior and sixth form. Founded in 1532, it operates as part of the Stamford Endowed Schools group, sitting within a Georgian market town approximately 90 miles north of London. The school holds membership of HMC (Headmasters’ and Headmistresses’ Conference), IAPS, ISC and BSA, and received a fully compliant ISI (Independent Schools Inspectorate) inspection in 2025 covering both its Junior and Senior Schools. Around 1,600 pupils are on roll. That scale supports broad academic and co-curricular programmes while the school’s structure keeps it personal in practice.
The curriculum runs through GCSEs and A levels, with the sixth form offering the breadth expected of an HMC school. The 2025 A level sitting produced a 100% pass rate across 192 candidates: 37.1% of grades at A* or A, and 65.7% at A*–B. Stamford operates what it calls the Diamond Structure. Pupils are taught co-educationally at junior level, separately by gender through the senior years, and together again in the sixth form. This shapes setting, house life and timetabling throughout — it is not a cosmetic distinction.
The sixth form draws pupils from across the Stamford Endowed Schools and is fully co-educational. The 2025 cohort of 192 candidates achieved a strong spread of top grades, and the large majority of leavers progress to their first-choice universities. The EPQ (Extended Project Qualification) is available alongside A levels.
A-Level results
2025: 10.5% A*; 37.1% A*-A; 65.7% A*-B; 87.1% A*-C; 100% pass rate; 192 candidates. Includes BTEC and EPQ.
Stamford offers both full boarding and day places on a seven-day programme. The headline annual fee for full international boarding is £45,000 (2025/26). Day fees run from £26,816 per year for Years 7–8 and £27,575 for Years 9–13. Pastorally, the Diamond model means separate senior school environments give way to a unified sixth form community. BSA membership reflects the school’s standing within the UK boarding sector.
With 1,600 pupils, Stamford has the scale to run a genuinely deep co-curricular programme. Sport, music, drama and a range of societies operate across the school year, from junior through sixth form, with provision shaped by the distinct structures of each phase. Details on specific clubs, competitions, and CCF (Combined Cadet Force) or DofE (Duke of Edinburgh Award) participation are best confirmed directly with the school, as the offer evolves year to year.
The school occupies a site in the centre of Stamford, a well-preserved Georgian town in Lincolnshire. The setting is compact and walkable. Stamford itself provides an unusually attractive backdrop for a UK day and boarding school — and sits roughly 90 miles north of London, accessible by road and rail.
East Midlands Airport is the closest regional airport, approximately 45 miles south-west of Stamford. London Heathrow, around 90–100 miles to the south, is the primary gateway for international families. Peterborough railway station, under 15 miles away, runs direct services to London King’s Cross in under an hour.
