This paper explores the predictive relationship between knowledge management (KM) processes and school intellectual capital (SIC). SIC is at the core of what society deems to be the purpose and definition of successful schooling. KM aims to support organizations in creating a mechanism that measures, stores and transforms knowledge into intellectual capital. Developing SIC for creating values and capacity is an important KM processes in all organizations. A cross-sectional quantitative survey was applied to identify the KM processes that would enhance the SIC. The data were collected from 458 teachers of four secondary schools, four primary schools and one special school, which were selected randomly in Hong Kong. Factor analysis and a reliability test were applied to confirm the construct validity and reliability of the instrument. Results of the factor analysis showed that knowledge creation was excluded from the KM processes while internal capital was split into structural capital and routine capital. Results of the multiple regressions showed that knowledge retrieval and knowledge sharing are the predictors of all four components of SIC, while knowledge application predicts human capital alone. These findings reflect that schools in HK have adopted personalization KM processes to develop SIC. School leaders could consider cultivating community of practices in their schools for developing SIC for sustainable development. © 2016, De La Salle University.
