Box Hill School is an independent coeducational boarding and day school situated in the village of Mickleham near Dorking, Surrey, England. The school has approximately 425 pupils aged 11–18. The school has a 60% day student:40% boarding student ratio, and as part of an international network (Round Square), around 25% of the students come from over 25 nations. The international environment of the school is deliberate, as part of the school's mission to develop students for life beyond school. Each student is assigned to a House on admission, with a family-based ethos and Houseparents to act as the guiding influence. The school has offered the International Baccalaureate since September 2008 and re-introduced A levels in 2013, meaning both are now available at Sixth Form.
