During recent decades, the notion of team leadership has emerged as a central theme in the international discourse on systemic education reform. This issue of "Research in Educational Administration and Leadership" not only captures a collective sense of commitment to education as means for advancing national social, economic, and political wellbeing but also reflects a changing nature of leadership across a wide spectrum of educational organizations and contexts. Given the increasing complexity of 21st century education, effective leaders at all levels tend to rely less on bureaucratic, hierarchical structures and more on relational approaches to accomplish tasks. In this regard, teamwork has become an indispensable characteristic of organizational life, and depending on the task, teams may involve a wide array of stakeholders (e.g., superintendents, school board members, district support staff, principals, teachers, parents, students) or a select few representing specific constituencies to address specific issues.
