In this study, 283 teachers from elementary schools at Sabzevar were  selected in multistage sampling method. The instrument for data collection was Persian version of the  Collective Teacher Efficacy Belief Scale developed by Tschannen-moran & Barr (2004). Internal  consistency investigated by Cronbach‟s alpha and factor structure's scale verified with exploratory  principal axis factor analysis and confirmatory factor analysis, too. Results indicated that Cronbach‟s  alpha for Collective Teacher Efficacy Belief Scale is 0/93 and all of items have high correlation with  total. Exploratory factor analysis with principal axis and varimax rotation indicated that this scale  consist of one component that explained 59/70% of the variance. Also scale‟ confirmatory factor  analysis confirmed one components structure that extracted. Findings of current study emphasize that  Collective Teacher Efficacy Belief Scale is a suitable instrument to assess collective self-efficacy's  Iranian teachers in various researches.
