Marlborough College is one of England's most celebrated co-educational boarding schools — a school that combines academic rigour with an extraordinary breadth of co-curricular opportunity on a magnificent 300-acre campus in Wiltshire. It has become one of the most popular boarding destinations for London and South-East families, and its 13+ entry via the ISEB Pre-Test and Common Entrance is competitive and well-established.
About Marlborough College
Marlborough College is located at The College, Marlborough, Wiltshire, SN8. It educates around 950 pupils aged 13–18, with the large majority boarding. The school is co-educational throughout — one of the relatively small number of prestigious full-boarding schools that educates boys and girls equally from the first year.
Marlborough's academic results are strong and improving year on year, with regular Oxbridge entry and excellent Russell Group university destinations. The school has particular strengths in art, music, science and outdoor education — its Duke of Edinburgh provision is exceptional — and the campus and facilities are among the best of any school in England.
The entry process
- Registration in Year 5 or Year 6 — families should register when their child is 10–11. Marlborough is popular and oversubscribed; registration well in advance of the Pre-Test is advisable.
- ISEB Common Pre-Test — candidates sit the ISEB online Pre-Test covering English, Mathematics, VR and NVR at their prep school. Marlborough uses the results alongside school reports to assess potential and to decide on assessment invitations.
- Marlborough's own assessment — shortlisted candidates visit Marlborough for academic papers and a housemaster interview. The school assesses academic ability, character and potential contribution to the school community.
- Conditional offer — successful candidates receive a conditional place subject to passing Common Entrance.
- Common Entrance in Year 8 — CE papers across major subjects. Marlborough's pass mark is typically around 55–60%.
Common Entrance at Marlborough
CE for Marlborough covers: English, Mathematics, Sciences, French, History, Geography, Religious Studies and optionally Latin. The CE pass mark requirement is accessible but represents a real hurdle for children who are not well prepared. Systematic subject preparation in Years 7 and 8 is necessary.
Scholarships
Marlborough awards scholarships in academics, music, art and sport. Academic scholars sit harder papers; other scholarships involve auditions, portfolio reviews or sporting trials. The College also has a bursary programme for means-tested support.
When to start preparation
- Year 4–5: English and Maths foundations, broad reading and co-curricular development. Outdoor pursuits and musical interests are particularly well suited to Marlborough's culture.
- Year 6–7: ISEB Pre-Test preparation and Marlborough's own assessment preparation.
- Year 7–8: CE subject preparation across all areas.
Why Marlborough?
Marlborough combines boarding school prestige with a genuinely warm and inclusive culture. It is a school where pupils are expected to work hard and pursue their interests vigorously — but not at the cost of wellbeing or breadth of development. It is particularly popular with families who want co-educational boarding, outstanding arts and science facilities, and a school that will develop a child into a genuinely well-rounded adult.
Its Wiltshire location — accessible from London (90 minutes by car), Bristol and the South-West — makes it a natural choice for families across a wide geographical area.
