The House Competition is based on net points, calculated as positive housepoints minus negative behaviour points. So when a student receives a positive point, their House also gains a point, and if a student receives a negative point, their House also loses that point. Students should work together with their housemates to get as many positive points as possible, and to avoid receiving negative points.
The current year's standings are published weekly on the BSK Facebook page.
