摘要:Abstract In recent years, teachers’ self-efficacy has demonstrated a profound influence on the daily lives of teachers and their students. However, little is known in pertinent to the relationship between teachers’ personality traits and their self-efficacy. To gain more insight into this area, this study sought to explore the interface between 100 male and female EFL instructors’ personality and their self-efficacy at 11 English language institutes in Bandar Abbas, Iran. In order to glean data, two instruments were applied: the NEO Five Factor Inventory (NEO-FFI-R), and Second Language Teaching Efficacy Scale (SLTES). Moreover, to see whether there was a significant relationship between the variables under study, Spearman Rank Order Correlation was applied to analyze the data. At the end, the results revealed that there is no significant relationship between EFL instructors’ personality and their self-efficacy.
