The present study was conducted to examine the impact of teacher leadership on organizational effectiveness in schools, with teacher self-efficacy serving as a mediating variable. This research is applied and descriptive-correlational. The population consisted of 1,309 elementary teachers in Hamadan city, with 302 (273 women, 29 men) selected via proportional stratified random sampling. Instruments included teacher leadership, Tschannen-Moran and self-efficacy, and organizational effectiveness questionnaires, with Cronbach's alphas of 0.93, 0.91, and 0.96, respectively. Data were analyzed using descriptive statistics (mean, standard deviation, Pearson correlation) and structural equation modeling. The research findings indicated that teacher leadership has a direct positive impact on teachers' self-efficacy (β = 0.50, T = 8.93) and organizational effectiveness (β = 0.22, T = 8.85). Additionally, teachers' self-efficacy plays a significant mediating role in transferring the effect of leadership to organizational effectiveness (β = 0.52, T = 3.92). The results of the study showed that teacher leadership plays an influential role in increasing the organizational effectiveness of schools, and this effect is largely realized through strengthening teachers' self-efficacy. Overall, teacher leadership not only leads to improved educational performance but also enhances the organizational functioning of schools, and the development of components such as ethics, a positive environment, and appreciation creates the groundwork for increasing motivation and organizational effectiveness.The findings of this study can provide a foundation for policymakers and educational administrators in designing teacher empowerment programs, strengthening their leadership roles, and enhancing school organizational effectiveness.
