Historically, the House System was established in boarding schools in British Commonwealth countries. Even when boarding schools decreased in availability, the House System continued to flourish and can now be found in schools and colleges across the world.

As a classical school, Twelve Stones chose the House System as its form of student government to create opportunities for student leadership and inter-grade relationships within each house. Houses cooperate with one another in service projects and chapels, while competing against each other in areas of academics and athletics. The House System is one of the practical ways the school’s mission statement is put into daily use.
