St Stephen's School is a K-12, co-educational independent, day school of the Uniting Church located on two campuses â one in Duncraig and the other in Carramar, two suburbs of Perth, Western Australia. The school is one of Western Australia's largest independent schools. The Duncraig campus opened in 1983 for Year 3 to Year 12 and the Carramar campus in Tapping opened in 2001 for Kindergarten to Year 12. In 2011 the school opened the new Early Learning Centre (ELC) in Hepburn Heights (across the road from the Duncraig campus) for Kindergarten to Year 2, introducing a Pre-Kindergarten, that takes place on Wednesdays, in the mid 2010s.
The school also owns a property, the Nanga Outdoor Education Facility (referred to by the school as "The Kaadadjan Centre") consisting of bushland, field, forest and 800 metres of Murray River frontage. The property is used for school camps and retreats, leadership development and team building activities.
Following the inception of the Uniting Church in 1977, St Stephen's School became the first school to be established under them, with council being formed in 1981, and building beginning in 1983.
On April 19, 2024, St. Stephen's School became the record holders for "most people launching confetti cannons simultaneously", setting the record at 2,013. The attempt included students and faculty from both campuses, with the event receiving media attention.
St Stephen's School's "House" structure is used to decide student homerooms, sporting events, or other similar matters. Houses are randomly assigned to students upon arrival at the school, however students with parents, or other immediate family members who attend(ed) the school will be assigned to the same house as their family members.
