For promoting co-operation and team spirit in sports and other activities, the school is divided into four houses. Each house has a captain and a vice-captain. Members of the staff are assigned to the houses. The houses are named after four Jesuit saints whom the school presents as role models to students. In their lives these saints exemplified competence, conscience, compassion and commitment included in the vision statement of the school.
