When coming to Winterburn, it quickly became apparent that Marilyn Schmitke has a core belief in the power and potential of people to affect change when they work together. She presented staff with the opportunity to look at school supports through a lens of student-centred conversations and a targeted approach to interventions - the Collaborative Response Model. Through a strategically crafted plan, creative scheduling and outstanding instructional leadership, Marilyn ensured the implementation of CRM was successful and sustainable. By her careful design, this strong collaborative environment has resulted in a profound shift in school culture to where teacher collective efficacy drives our work with students. Because of Marilyn's leadership, vision and commitment to supporting all students, we continue to use CRM as our framework to create structured supports to respond effectively to student's unique needs.
