ACS Cobham International School is a co-educational private boarding school located in Cobham, Surrey, about 20 miles from London. Established in 1967, it forms part of the ACS International Schools network, which includes four campuses worldwide, one of them in Qatar. The Surrey campus educates around 100 students aged 12–18 and offers boarding from the age of 14.

The school delivers two internationally recognised academic pathways: the International Baccalaureate (IB) and the American Advanced Placement (AP) programme. Teaching is conducted in a highly international environment: across the ACS network, students represent many nationalities and collectively speak more than 40 languages. Academic outcomes are strong, with an average IB score of 33 points and over 93% of students achieving this level, while 77% of AP students score 3 or higher. Graduates progress to leading universities in the UK, including Oxford, Cambridge, Bath, Exeter and King’s College London, as well as top US institutions such as Yale, Harvard, Columbia and Chicago.

Admission requires English proficiency at B2 level or above, recent academic records, teacher recommendations and a motivation letter; subject tests may be required. Achievements in sports, science or the arts are considered an advantage. English language support is available for international students through small, interactive classes.
Boarding students live in single-sex residences with double rooms, private facilities, internet access and shared study and recreation areas. Full board catering is provided. The 128-acre campus includes modern academic buildings, laboratories, a library, creative studios and extensive sports facilities, including swimming pools, tennis courts, football and rugby fields, athletics tracks and a golf course.

The academic year runs from August to June and is divided into two semesters, with additional fees applied for registration, deposits, examinations, excursions and related services.
