The purpose of the current study was to investigate the relationship between principal distributed leadership and teacher job satisfaction, with the mediating role of collective teacher efficacy. It also investigated the moderating role of teacher commitment in the link between collective teacher efficacy and teacher job satisfaction. Drawing data from a sample of 338 Turkish language teachers in secondary schools in Turkey, the current study employed a cross-sectional survey design. Moderated mediation structural equation modeling was utilized to analyze the data. Results provided a moderate direct association between distributed leadership and teacher job satisfaction and an indirect relationship mediated by collective teacher efficacy. Researchers also found the moderating role of teacher commitment in the relationship between collective teacher efficacy and teacher job satisfaction to be positive and significant. Results provide evidence from a non-Western developing context and Turkish language teachers, contributing to the global knowledge base by confirming the positive and direct link between distributed leadership and teacher job satisfaction while highlighting the significant mediating role of collective teacher efficacy between these two constructs and the moderating role of teacher commitment in reflecting this role in teacher job satisfaction. Implications for policymakers and practitioners are discussed.
