Objectives: Employee’s occupational success is one of the factors that separates efficient organizations from inefficient organizations. Employee’s occupational success can be predicted based on individual and organizational variables. This research aims to present a regression model for predicting occupational success based on the variables of person-organization fit and organizational commitment as well as the components of these two variables. Methods: The population of this research includes 777 employees of Bu Ali Sina University in 2016. The research sample was selected using a randomized sampling method (N =256). Standard questionnaires were used to collect data. Results: Based on the findings, the variables of person-organization fit and organizational commitment are able to predict 24% of dispersion of occupational success with regression coefficients of 0.149 and 0.248, respectively. In addition, the components of knowledge, normative commitment and interests can only predict 30% of dispersion of occupational success with regression coefficients of 0.537, 0.505 and 0.644, respectively. Discussion: The findings of this study are consistent with those of research in this regard.
