Employee innovative behavior is crucial in an era characterized by rapid change and intense competition. This research aims to investigate the influence of organizational commitment on teacher innovative work behavior, mediated by knowledge sharing. A total of 191 teachers from several prestigious private schools in Jakarta, Indonesia, agreed to participate as respondents by completing an online questionnaire. The analysis employed Structural Equation Modeling (SEM) with SMART Partial Least Squares (SMARTPLS). The results indicate that affective and continuance commitment significantly influence teacher innovative behavior both directly and through the mediating role of knowledge sharing. However, normative commitment was not found to have a significant influence on innovative behavior. These findings are expected to provide valuable insights for the development of human resource management strategies in the education context and contribute significantly to the enhancement of overall education quality.
