The house system was introduced in 1899 by the then headmaster Frederick Arthur Hillard. Initially six houses were established, and membership of houses was based on the place of residence of each boy. The original houses were: Boarders, Barbourne, City, St. John's, County A, and County B. In 1909 the house system was changed to reflect the increasing number of boys in the school, and the difficulty of allocating pupils on the basis of where they lived. The six houses created in 1909 were: School House, for boarders, (which, due to common usage, changed to Whiteladies, as this was the building in which the boarders lived); Temple (after Henry Temple, headmaster 1850s); Tudor (after Elizabeth I); Woolfe (after Richard Woolfe, benefactor 1877 ); Wylde (after Thomas Wylde, benefactor 1558); and Yewle (after Robert Yewle, Six Master 1561). In 1963 two additional houses were created by the then headmaster Godfrey Brown, namely Langley (after William Langley, Six Master 1561) and Moore (after John Moore, benefactor 1626).
