This study was conducted to analyze the relations of teacher trust, teacher efficacy and school climate in elementary schools. In particular, this paper focuses on investigating the effects of school climate and school trust on teacher efficacy. In order to carry out this study, 215 participants working in Seoul and Kyonggi Province were collected. Descriptive analysis, Pearson s correlation, and SEM(Structural Equation Modeling) are deployed to examine the relations between the teacher trust, teacher efficacy and school climate by using the SPSS PC 22.0 and AMOS 18.0 program. The results of this study appear as follows. First, All variables were positively correlated. For instance, correlations between teacher efficacy and principal leadership (r=.30, p<.01), teacher efficacy and principal trust (r=.45, p<.01) were significant. 2) Results of the SEM illustrate that teacher trust indicator has direct impacts on the teacher efficacy, but school climate has indirect influence on the teacher efficacy. As the result of the goodness-of-fit indices, the fit of the model was satisfactory. Although the influence of the principal is limited by the school level, principal leadership is influenced by the organizational climate. It also suggests that teacher efficacy may vary depending on how teachers perceive it.
