Book excerpt: The Warrior Principal: New Leadership for Urban Schools is a marriage between the Art of War and effective school leadership principles. It describes the mentality and actions school principals need in order to spearhead the process of successfully reforming a failing and/or struggling urban public school. This book also instructs principals on how to deal with resistance caused by change, district- and building-level politics, and ineffective staff members. It also provides a framework for improving staff morale, boosting student achievement, delegating authority, and creating a positive school culture.
