This research generally intended to ascertain how organizational commitment was influenced by psychological empowerment, job autonomy, and distributive justice of tertiary school leaders in selected colleges and universities in Southern Philippines. Two hundred fifty-two (252) tertiary school administrators with at least three years of experience in Southern Philippines as program heads, deans, directors, vice presidents, and presidents made up the participants. The "Basic Social Justice Orientations Scale," "Psychological Empowerment Scale," "Job Autonomy Scale," and "Organizational Commitment Scale" were employed to collect data needed for this study. Then, Pearson r product-moment correlation, multiple regression analysis, and path analysis were applied to evaluate the data. Research findings supported the hypotheses that were developed in the theoretical model. The findings demonstrated that job autonomy acted as a mediator between distributive justice and psychological empowerment, which has direct and indirect consequences on the organizational commitment of school leaders. Additionally, it was discovered that both psychological empowerment and job autonomy greatly affected organizational commitment. Therefore, it can be said that the distributive justice, psychological empowerment, and job autonomy of selected tertiary school leaders in Southern Philippines had influences on their organizational commitment. This means that distributive justice, psychological empowerment, and job autonomy are good predictors of the organizational commitment of tertiary school leaders.
