When a student begins at Darfield High School, they become a member of one of the four Houses. Each House is run by a Staff Leader and a House Leader, a senior student who liaises with the students. The House system was re-introduced to encourage a positive atmosphere at Darfield High School and to enhance participation in events and relationships among students.

Students participate in various events (see House points), covering sporting, cultural and academic activities, to ensure that everyone has an opportunity to contribute. Placing in specific events and participation in events are both rewarded, provided that students are honouring the spirit of the event.
