This book constitutes a collection of case studies that explore issues faced by school principals as is related to instructional leadership. The scenarios presented here allow students to gain a more thorough understanding of the Professional Standards for Educational Leaders (PSEL, 2015) and their performance competencies. These scenarios are designed to develop new school leaders. These cases provide opportunities to create meaningful learning experiences for courses, professional development programs, and the mentoring of new school principals, giving them exposure to the kinds of dilemmas they will encounter as they take on their leadership roles or start out on supervisory positions. The cases are based on real life dilemmas, reflect contemporary issues in our school buildings, and are designed to be easily used or adapted across all school types. The cases are taken from many years of experience as an educator, administrator consultant and researcher in rural, suburban and urban school districts.
