ACG School Jakarta has four houses from Kindergarten to Year 12. The Biawaks, Cicaks, Gekos and Komodos all contribute to ACG School Jakarta’s spirit in many ways. Each house has their own colour and logo and, when house events are run, all students don their colours in support of their house. Students stay in their allocated house throughout their schooling at ACG School Jakarta. Where possible, they are placed in the same house as siblings or parents. The house events encourage students to develop friendships across different year levels and extend their teamwork, leadership and sportsmanship skills. House events are run throughout the year and include the annual Swimming Carnival and House Sports Carnival. There are also regular lunch-time intermural house competitions. In an effort to acknowledge and honour the animals native to Indonesia, the names for each house are different lizards found throughout Indonesia.
