Ancient Schools' group
The Ancient Schools’ Group is an informal, prestige-based association of some of the oldest independent schools in the United Kingdom, typically those founded before 1600. The group aims to facilitate the exchange of best practices and foster collaboration among institutions that share unique challenges related to heritage, ancient endowments, and historical estates. Governed through periodic meetings of Heads and Bursars, the group provides a forum to discuss the preservation of tradition within a modern educational context. Membership is exclusive and includes renowned institutions such as Eton, Winchester, Harrow, and Westminster.
