Coinciding with the 2016 Annual Conference in Vancouver, British Columbia, Learning Forward commissioned and supported a study of professional learning across the nation of Canada entitled "The State of Educators' Professional Learning in Canada." A research team led by Carol Campbell, Associate Professor of Leadership and Educational Change at the Ontario Institute for Studies in Education (OISE), University of Toronto, examined the professional learning that educators experience in the provinces and territories of Canada. The study identifies key components and features of effective professional learning and highlights findings from what educators in the nation experience. Among the reports and papers resulting from the study, this report provided a call to action building on the Canada study. Here, Fullan and Hargreaves outline an argument for meaningful professional learning and development. They conclude with actions for teachers, systems, and Canada to take to establish a culture of collaborative professionalism. Subsequent reports and papers resulting from the study will be offered as they are completed.
