Since its introduction more than eighty years ago, the House System has helped schools promote personal responsibility and a sense of belonging among pupils. These smaller school communities encourage healthy rivalry through friendly games and extracurricular activities.

The system develops teamwork, leadership, cooperation and individual strengths while building friendships among pupils of different age groups. Students join a House when they enter the school and remain members until they leave.

As students progress into senior classes, they take greater responsibility for managing their Houses and coordinating activities, helping them develop confidence, initiative and organizational skills.

At APSACS, the House System is designed to encourage participation, healthy competition and a strong school community. The traditional school sports day is organized as an inter-house competition.

Debating competitions, charity drives and community service activities can also be organized between Houses. Merit points for behaviour and academic achievement may be recorded and compared to recognize consistent effort and positive contributions.

Students may be assigned to Houses according to their performance, ability and talents, with the aim of maintaining a reasonable balance between Houses and encouraging fair competition.

Traditionally, once a student has been assigned to a House, younger siblings joining the school may also be placed in the same House. This tradition may sometimes extend to children of former students.
