This revised edition of the bestseller by Douglas B. Reeves contains the information and tools necessary to successfully evaluate all types of educational leaders and improve individual and organizational performance. Based on research, theory, and best practices of leadership, organizational effectiveness, and personnel evaluation, this book focuses on three critical concepts: leadership has a dramatic impact on student achievement, equity, and staff morale; leadership effectiveness includes both personal predispositions and acquired knowledge skills; and, leadership evaluation is intended to improve personal and organizational performance, not merely to render an assessment.
