In this episode we learn about how the leadership team at St Mary Mackillop Catholic College in Canberra successfully implemented the components of Catalyst and scaled up for a two-campus school with over 2000 students. Erin White and Lisa Buckland share with us their insights about how they started their Catalyst journey and the importance of this work in the Secondary context, discussing what worked well and some of the challenges they faced along the way. We learn about where they prioritised, invested their time, supports and resources and how they keep momentum with over 200 staff. Everything shared has relevance for all school contexts, making this an interesting episode for all.
