This study examines the influence of organizational justice at H University, Central China, on undergraduate students' professional commitment, with a focus on the mediating role of academic stress. Employing descriptive statistics, correlation and regression analyses, and structural equation modeling, the research validates its hypotheses. Results indicate that a lack of organizational justice at the School correlates negatively with students' professional commitment and positively with academic stress. Academic stress notably predicts professional commitment levels and partially mediates the relationship between the School's organizational justice and students' commitment. To boost professional commitment, enhancing students' professional recognition is vital, alongside adapting to future trends, improving interpersonal communication, and respecting student independence. Additionally, addressing academic stress from various angles, including internal and external environmental factors, is imperative for overall student well-being and commitment.
