Turnaround principal actions and competencies are the leading indicators for turnaround principal success. The competencies—the habits of behavior and underlying motivations that help predict how principals will do their jobs—can be used for turnaround principal selection, evaluation, and development. The actions—the specific maneuvers a turnaround principal must execute for leading a successful school turnaround effort—serve as guidelines to focus turnaround principals on how their difficult work will be accomplished. Self-assessments of competency and actions allow the turnaround principal to reflect on current strengths and areas for leadership development.
