In spite of the significant role of teachers in the efficacy of classroom management particularly in teaching English as a Foreign Language, the issue has not been addressed sufficiently especially in relation with other individual variables. Hence, this study made an attempt to investigate the association between Iranian EFL teachers’ classroom management, reflective thinking and transformational leadership style. 247 English Foreign Language teachers took part in the study. To measure the variables of the study, Teachers Sense of Efficacy Scale (Tschannen-Moran & Woolfolk Hoy, 2001), Reflective Thinking Scale (Choy & Oo, 2012) and Multifactor Leadership Questionnaire(Avolio, Bass & Jung, 1995) were used. Structural Equation Modeling (SEM) was applied to test the hypothesized model of associations. After confirming the hypothesized model (= 1.275; RMSEA=.02; RMR =.03; GFI =.97; AGFI =.93; NFI =.97; CFI =.99; IFI =.99), the results revealed significant internal correlations among the main as well as the sub-scales of the study. Multiple regression analysis further confirmed the direction of the path model proposed for the study. Generally, it was concluded that reflective thinking and transformational leadership improve teachers' efficacy of classroom management which, in turn, facilitates teaching processes. Implications are discussed.
