There are four school houses: Green, Yellow House, Red and Blue. Each house has a house mistress and a captain, usually a Form Four student, and an assistant captain, usually a Form Three student. The captain and her assistant are voted in annually by the teachers. The houses compete in sports, merits and demerits, and other aspects of school life. The winning house is announced at the end of the year and gets to go on a special trip while the other houses remain in school.
