Self-efficacy significantly influences the success of school leaders in managing the school environment, offering instructional programs, and working morally with the community. In this study, I addressed the following questions: What are school leaders' self-efficacy and its various components of management, instructional, and moral leadership? What patterns emerge based on level, position, gender, and years of experience? Approximately 1,300 Alabama school leaders (i.e., principals and assistants) were invited to take the Tschannen-Moran and Gareis' Principal Sense of Self-Efficacy Scale. This 18-item instrument, using a 9-point Likert response scale from 1 (none at all) to 9 (a great deal), explored the overall self-efficacy of leadership and its three components. The Alabama participants, 402 school leaders with a response rate of close to 20%, revealed strong self-efficacy (M = 7.44, SD = 0.83), and for its various components of management (M = 8.15, SD = 1.42), instructional (M = 7.61, SD = 0.87) and moral (M = 7.75, SD = 0.86) leadership. In looking at background characteristics, self-efficacy was found to be significantly influenced by the type of school, the leadership position, gender, and years of experience. For instance, self-efficacy was higher for elementary school leaders, principals, women, and those leaders with 15 or more years of experience. Interestingly, the assistant principals' self-efficacy pattern in management was noteworthy. These findings have practical implications for educator stakeholders and future avenues of research, as they provide insights into the role of school leaders' self-efficacy in management, instructional, and moral leadership and the influence of background characteristics on this self-efficacy, thereby highlighting the need for further investigation into the complex interplay of these factors.
