The exploration of the intersection of leadership practices from the school principal and other educators, the school culture, and the school success across different high-need contexts and cultures make this volume unique. Chapters in this volume present original investigations or reanalysis of empirical research enhancing our understanding of the interrelationship between leadership, culture and success through descriptions of practice that can contribute to lessons in leadership for school improvement. When considering a culture of success, leadership that focuses on impacting schools in high-need areas bring about lessons on how to create sustainable environments for student learning in challenging contexts. High-need schools include not only socioeconomic challenges influencing the performance of students. It includes multiple external and internal factors impacting leaders, teachers, students, and their families, affecting the management of structures, processes, and most importantly, learning. In the quest to improve high-need schools, and understand strategies for principals dedicated to a variety of contexts, this volume brings lessons with application for researchers, policy-makers, and practitioners who want to join in the quest to improve the quality of education among worldwide communities.
