Purpose-This paper aims to analyse the relationship between the organizational commitment, the knowledge transfer and the knowledge management maturity at a Brazilian public university. As indicated in the literature, the organizational commitment and the influence on knowledge management in the public sector, especially in developing countries, configures an important gap to be filled (Razzaq et al., 2018). Design/methodology/approach-The research has a descriptive and quantitative nature, and to run the analysis, an exploratory factorial analysis was conducted and after that a structural equations modelling was carried out. Findings-The results indicated a significant relationship between the organizational commitment to the knowledge transfer and, consequently, to the knowledge management maturity. Originality/value-In the first place, the model including all dimensions of commitment: affective, calculative and normative with knowledge transfer and knowledge maturity was not tested before. Second, data on the public sector in developing countries are still rare and studies in this field encouraged (Razzaq et al., 2018). In this case, the present study contributes in this field, specifically in the education sector. Finally, understanding the individual commitment profile helps to understand the extent to which that person contributes both to the knowledge transfer, and therefore, in the same analogy, to the knowledge management maturity level.
