The house system is a traditional feature of schools in the United Kingdom. The practice has since spread to Commonwealth countries. The school is divided into units called "houses" and each student is allocated to one house at the moment of enrollment. Houses may compete with one another at sports and maybe in other ways, thus providing a focus for group loyalty.
