The document discusses the evolution of professional learning teams (PLTs) at Lochearn school over three years from an "add-on" to a "way of being". It began with one hour per week focused on questions from Dufour but grew to include deeper conversations around best practices. Administration took on a coaching role to focus discussions on improving student learning. PLT meetings now align with school and grade goals and include discussion of student achievement data and differentiation strategies.
