The main aim of this study this study was explaining the structural model of teacher's perception of school's social capital and teacher's psychological capital with their readiness for change in primary schools. The research statistical population was included all primary school teachers (17500) in Fars province, that 733 of them were selected as the research sample by using systematic sampling method. The research instruments were included three questionnaires: social capital, psychological capital and readiness for changing, which were distributed and collected after calculating validity (speciation analysis) and reliability (Cronbach's alpha). Research data were analyzed using one-sample t-test, Pearson's correlation's matrix and multivariate regression (structural equation model) and also Amos23 and Spss25 software. Findings showed that while the average dimension of social network was higher than the desired level, the rest of the dimensions of social capital and the average total of social capital was less than the desired level. The average of teacher’s psychological capital and all its dimensions was higher than desired. Examining the simultaneous role of social capital and psychological capital in predicting readiness for change, it was concluded that social capital loses its predictive power for readiness for changing (β= 0/07 & p= NS) and psychological capital have a positive and significant predictive power for readiness for change (β= 0/62 & p< 0/01). The output of this research can be use by managers, teachers and other staff in different domains to providing readiness ground for change by developing and strengthening the capacities of psychological capital.
