Norwood International High School house system has been a part of the school since 1993.
The system has evolved over time to increase the connection of students and staff, through changes to house names, an increase in activities and events, and increased opportunities for students to become involved.
Each student and staff member belongs to one of four houses: Morialta, Lofty, Murray or Torrens. Students compete in a range of events and competitions throughout the year to receive points for their house. Each house has student representatives who lead the house system and their allocated house.
