This study aims to examine the relationship between the perception of organizational justice and gender in educational organizations using the meta-analysis method. Additionally, the study explores the impact of moderator variables, including year, thesis/study type, field of study, participants, school type, and applied region, on the relationship between organizational justice perception and gender. The research begins with a comprehensive literature review that identified 883 academic theses. These theses were then screened based on inclusion criteria, resulting in 86 independent theses that met the criteria for meta-analysis. The meta-analysis encompassed a total sample size of 37,192, with 20,503 females and 16,689 males. The study findings indicate a significant gender-based difference in organizational justice, favoring men [k = 86, d = -0.062, 95% CI (0.096, -0.028), p < 0.05]. Additionally, the results show that the relationship between gender and organizational justice perceptions remains consistent across various moderators. Based on these findings, it is recommended that researchers conduct causally-determining studies, while educational administrators should focus on enhancing interactional, distributional, and procedural efforts to improve the perception of organizational justice, particularly among women.
