A significant research base has increasingly substantiated that teachers are among the most significant players affecting student achievement in second language classrooms. As a result, teacher-related variables have enjoyed much research attention over the recent decades in both mainstream education and English Language Teaching (ELT). Likewise, the present study was set to test a structural model of collective teacher efficacy, teacher self-efficacy, job satisfaction, and teaching commitment, and specifically to examine the hypothesis that teaching commitment mediates the effects of collective teacher efficacy and teacher self-efficacy on job satisfaction. Using a sample of 312 Iranian EFL teachers, structural equation modeling (SEM) was conducted to establish the structural model. The findings of a confirmatory factor analysis (CFA) confirmed the fitness of both the employed scales and the structural model. The findings and implications of the present study are finally discussed.
