Previous studies reveal a gap in literature relating the contribution of personal knowledge management (PKM) at the individual level within organization. In addition, the mediating role of organizational learning in the relationship between transformational leadership on personal knowledge management is less studied. Therefore, this study aims to address the gap by investigating the combined effects of transformational leadership, information and communications technology (ICT) literacy, and organizational learning toward teachers' PKM in the context of school in Indonesia. It is also aimed to explore the role of organizational learning as the mediating variable. We collected questionnaire data from 80 teachers at an international school in Jakarta, Indonesia and used partial least squares structural equation modeling to examine the data. Our findings showed that ICT literacy, transformational leadership, and organizational learning culture positively affect PKM. ICT literacy found to have the biggest impact on the PKM of the teachers. In addition, organizational learning found to mediate the effect of transformational leadership on PKM, even though the increase is not high. These findings provide managerial implications for the school management to improve their ICT literacy by building ICT literacy ecosystem in the school to improve teachers' PKM.
