In order to better understand the link between High-Performance Human Resource Practices (HPHRPs) and outcomes, this study examines the mediating roles of person–job fit (PJ fit) and person–organization fit (PO fit) using congruence theory. Through a survey questionnaire, data were gathered from 296 people who work at educational institutions in China. The results demonstrated that the association between HPHRPs and outcomes is mediated by both PJ fit and PO fit. We observed theoretical implications and discovered that HPHRPs are an important antecedent that builds congruence among employees' values and goals and organizational values and goals, as well as their job goals, which in turn prevents employees from experiencing stress and developing intentions to leave their workplace. The current study adds to extant literature on education and HPHRPs by identifying PJ fit and PO fit as mechanisms through which HPHRPs demonstrate their authority on employee outcomes. The managerial implications, limitations, and directions for future studies are included in detail at the end.
