Schools are complex and complicated human systems. As such, those who lead schools as principals need diverse and varied skills. A Guide to Managing and Leading School Operations: The Principal’s Field Manual by Dr. Jerome Cranston clearly recognizes and understands the complexity and nuance of this leadership position. By explaining the convergence of leadership and management, Dr. Cranston displays his unique understanding and experience as a principal. As educators, we often bring strong leadership and instructional skills to the position of principal but it is the management requirements that must be learned ‘on the job’. Dr. Cranston’s field manual will aid many a new principal in this highly specialized position and relieve much of the angst they feel in their first few years.
