The house system at ISA Tianhe is structured to instill a sense of camaraderie, encourage healthy competition, develop school spirit and reward positive actions. The school assigns each new student and teacher to a house when they first arrive, and they remain with that house throughout their years in the school. This fosters a sense of unity and loyalty between the younger Early Years students and the older Primary students, who act as role models. Moreover, all family members will be designated the same house.
Each house accumulates points throughout the year based on student participation in all aspects of student life. The house that accumulates the most points by the end of the year receives the ISA Cup in a school-wide awards assembly. Each house has a Captain and Co-Captain who assist the PE staff in matters related to house system organisation.
