Written for principals, district leaders, policy makers, and professors, this guide outlines a process for collecting information, making decisions, and taking action to improve instruction and student achievement. Militello (educational policy and leadership studies, North Carolina State U.) et al., who have been practitioners, professors, and policy makers, argue that leadership practices can be taught and explain each step of a collaborative inquiry-action cycle, the roles of the inquiry-minded, action-oriented principal, and putting concepts into practice.
