The Wennington School Association was formed by a group of old scholars, parents of old scholars and members of staff in the late 1940s to promote and continue friendship amongst its members. Membership is open to former scholars, the parents of former scholars, to former members of staff, and to people whose interest makes their membership desirable. Until the school closed in 1975 the Association gave the school support by holding annual Old Scholars working parties to assist in the maintenance of the building and grounds. Since 1998, when the Wennington records were transferred to the Planned Environment Therapy Trust for safe-keeping, the Association has actively supported the Trust by helping to catalogue and digitise the material in the archive.
