This collection contains a variety of material relating to the School’s religious services, primarily focused on Westminster Abbey. There are orders of service from the annual School services held at the Abbey, as well as further material from Abbey events that were often attended by the School, although did not feature it in any prominent way. Finally there is a subsection for Funerals and Memorials, containing orders of service for people related to the School or the Abbey. Many, but not all, of these services were held in Westminster Abbey.

Material generated through the School's events in or relationship with the Abbey, including annual services, weekly Abbey talks, and one-off events. Some items are also included by merit of their religious themes, such as Holy Communion orders of service, but are not specifically tied to the Abbey itself.
Westminster Abbey documents relating to the biannual Commemoration of Benefactors and the annual Election service are held in the EVE series, under their respective events.
