The main objective of this study was to investigate the role of cultural capital in knowledge sharing through the mediation of perceived organizational support among junior high school teachers in Mamasani city. The present research method was descriptive and correlational. The statistical population of this study was 420 junior high school teachers in Noorabad Momsani city. To determine the sample size, Morgan table was used and 225 people were considered as the statistical sample size. The sampling method was stratified random. To collect information, Bourdieu's Cultural Capital Questionnaire (1977), Vatankhah et al.'s Perceived Organizational Support Questionnaire (2017), and Dixon's Knowledge Sharing Questionnaire (2000) were used. To determine the validity of the questionnaires, a number of expert professors in this field were consulted and finally, the validity of the questionnaire was confirmed. To confirm the reliability, Cronbach's alpha coefficient was used, and the results were 0.801 for knowledge sharing, 0.839 for perceived organizational support, and 0.845 for cultural capital, respectively, indicating acceptable reliability for these questionnaires. Correlation, regression, and structural equation methods based on SPSS27 and PLS3 software were used to analyze the data. The results showed that the role of cultural capital in knowledge sharing through the mediation of perceived organizational support in teachers was positive and significant.. Therefore, it is appropriate to pay more attention to the variables of cultural capital and perceived organizational support in order to share knowledge in the target community.
