This book highlights the most difficult and complex decisions that expert high school principals make, the factors that expert principals consider and the processes that they utilize in their decision making. It examines the impact of difficult decisions that principals make, the components of the decisions that caused them to be difficult, leadership guiding principles, and the impetus for decision making. The work is based on a study of 21 high school principals in Massachusetts, Maryland, and North Carolina that was conducted to investigate the decision making practices of principals. McLaughlin offers a solid theoretical and research-based foundation and will provide principals with tools to make effective decisions. It differs from other books on that market in that it features an array of case studies and practical stories of actual experiences of principals in the field.
