This quantitative, descriptive, correlational study sought to describe the nature of the relationship between the self-efficacy of school principals and their job satisfaction.

The independent variables included demographic characteristics of respondents and principal self-efficacy as measured by the Principal Self-Efficacy Scale (Tschannen-Moran & Gareis, 2004). The dependent variable was principal job satisfaction, as measured by the Minnesota Satisfaction Questionnaire Short-Form (Weiss, Dawis, England, & Lofquist, 1967).

The study revealed that a principal’s self-efficacy level contributes significantly to his or her job satisfaction, a finding with implications for principal retention
