A 2021 SPE Outstanding Book Award Winner Studies of teacher leadership have proliferated over the past fifty years. Earlier work tended to focus exclusively on the link between teacher leadership and school improvement. Now, however, cross-cultural research on the relationship between teacher leadership and power, agency and school culture has the potential to contribute to a deeper understanding of the teaching profession in diverse geographical and social contexts. A Cross-Cultural Consideration of Teacher Leaders' Narratives of Power, Agency and School Culture presents groundbreaking work that expands discussions of teachers' work to highlight the struggles of a profession in three different countries: England, Jamaica and the United States. This research provides examples of teacher leaders' narratives about power, agency and school culture, presenting the voices of teacher leaders across diverse contexts. It identifies the "lessons" that transcend culture and speaks to the importance of understanding how teachers' work (and teacher leadership) functions within complex school cultures. This work has profound implications for teaching, learning and leading in a 21st century global economy. Perfect for courses such as: Teacher Leadership - Educational Leadership and Management - Teaching and Teaching Methods - Action Research/Applied Research.
