Milliken is a school with lots of spirit, and nowhere is this more evident than in our Houseleague activities. There are four houses at our school, each one a kind of horse, as we are the Milliken Mustangs. Each house has a symbol that represents it, as well as a colour. The Arabians are represented by an Arabian horse and their team colour is yellow. The Broncos are represented by a bucking Bronco and their team colour is red. The Palominos are represented by a Palomino horse and their team colour is blue. The Unicorns are represented by a Unicorn and their team colour is green.

Throughout the year, there are a variety of different activities that students can participate in to earn points for their Houseleague team. By participating in the Spirit Days each month, or by wearing team colours and coming out to play in our Houseleague tournaments each term, our students engage in lively competition with each other.
