This study was motivated by the premise that no nation grows further than the quality of its educational leaders. The purpose of this theoretical debate is to examine the wider context of leadership and its effectiveness towards improving school management. This academic evaluation examines recent theoretical developments in the study of educational leadership in school management. It begins with a concise overview of the meaning and concept of leadership in terms of research, theory, and practice. This is followed by an examination of the theories of leadership, principles and styles of leadership. Each section ends with an identification of contemporary issues and possible means of amelioration. This article concludes that success is certain if the application of the leadership styles, principles and methods is properly and fully applied in school management because quality educational leadership tradition offers great opportunity to further refine educational leadership and management policies and practices by accepting and utilizing the basic principles and styles of educational leadership.
