This study delved into the dynamics between social capital and human capital and their influence on the knowledge management practices of teachers in Tehran, Iran. The researchers adopted a random sampling method, selecting 214 participants, and administered three standardized questionnaires to collect data. Data analysis was conducted using the Structural Equation Modeling approach. The findings of the study revealed that social capital did not have a significant impact on knowledge management. The researchers attributed this to the presence of a weak culture of teamwork among Iranians, a subject they elaborated on extensively in their article. However, the second hypothesis indicated that social capital significantly influenced human capital, while the third hypothesis demonstrated that human capital had a substantial effect on knowledge management. The fourth hypothesis proposed that social capital influenced knowledge management through the mediating role of human capital, and this effect was found to be significant. These research findings highlight the distinct roles played by social and human capital in knowledge management, with human capital emerging as the more influential factor. Moreover, the study not only explored the direct relationship between social capital and human capital but also emphasized the mediating function of knowledge management within these associations. This novel perspective can enhance our comprehension of methods to enhance human capital within organizations by harnessing the potential of social capital and effective knowledge management
