The Farleigh Society was established in the late 1990s for former pupils of Farleigh School, to enable them to forge life-long links between each other and the School. All pupils who leave the school are warmly invited to join the Farleigh Society which exists to support and connect past pupils throughout their lives.

Farleigh Society members benefit from: a lively programme of reunions and social events to keep past pupils in touch with each other and the school; sporting and interest groups; mentoring, professional groups and networking events to support their careers; and access to Farleigh Connected, where past pupils can network with each other as well as the wider Farleigh community including current and past parents and staff.
