Aim: The Teachers' Sense of Efficacy Scale (TSES) is a prominent instrument that measures teachers' personal efficacy. This study was developed for investigating the psychometric properties of this scale in the Iranian teachers. Methodology: In this study, 255 Iranian teachers from elementary schools were selected with multistage sampling method. The instrument for data collection was Persian version of the TSES. Internal consistency of the scale was investigated by Cronbach's alpha, and factor structure was assessed with exploratory and confirmatory factor analyses. Results: Data analysis showed that Cronbach's alpha for the scale and subscales is high and all items have high correlations with the whole data. Exploratory factor analysis using principal components with varimax rotation showed that the scale consists of three components which explain 71.67% of the total variance. The summary of fitness indices from confirmatory factor analysis also represented the fitness of model and confirmed the three-factor structure. Conclusion: Results showed a good reliability and a stable factor structure for the scale in the Iranian contexts, similar to the developed cultural contexts.
