Objectives: This study aimed to investigate the relationship between the components of effective organizational maturity and Islamic justice at Farhangian University of Mazandaran province.y Materials and Methods: The research was a mixed method ؛ it was exploratory in the qualitative part and a survey in the quantitative part. The statistical population of the study was experts, specialists, and members of the faculty of Farhangian University of Mazandaran province ؛ 20 of whom were selected by convenience sampling method. To formulate a conceptual model of the research, the predictors and consequences of organizational growth have been identified. For this purpose, the relationship between Islamic justice and organizational maturity was studied and Islamic justice (procedural, distributive, transactional, exchange, and information justice) was studied as an effective variable on organizational maturity. Then, using the structural equation model, the conceptual model of the research was studied and analyzed. The conceptual model of the research was evaluated by analysis of variance and heuristic factor analysis by using SPSS software version 24 and LISREL.e Discussion and Conclusion: The results showed that distributive justice had the highest impact on organizational maturity ؛ procedural justice in the second rank and reciprocal justice in the third rank and transactional justice in the fourth rank and finally information justice had the least impact. In other words, the most explicit example of justice for the respondents is distributive justice which leads to the maturity of the organization as much as possible ؛ so managers and the payment system should pay more attention to the distribution of facilities, resources, and students. By strengthening individual and organizational interests and also observing organizational justice, we can improve the formation of respectful behavior and civic virtue in employees in terms of organizational citizenship behavior. Also, by creating organizational maturity based on justice and also paying attention to these two categories in drawing goals and organizational policy, the sense of participation and the spirit of altruism and the role of commitment and belonging of employees in higher education institutions can be promoted. Finally, by implementing the proposed model, the coordination and coherence between the functions, activities, and goals of the organization will increase.
