This research aims to investigate the process of institutionalization of Junior Enterprises (JEs) of the public universities of Ceará, according to the model of institutionalization of Tolbert and Zucker (1999) in its three phases: habituation, objectification and sedimentation. This research is bibliographic, being classified as a descriptive study of qualitative and quantitative nature. The study was conducted in 10 JEs of Ceará. During data collection, questionnaires administered with members, and interviews with the presidents of the JEs were used. The results show that the main reason for the emergence of IOs in public universities of Ceará was the need to combine theory with practice, the main actors in the process of these entities were students. No resistance groups, but there is a threat at the prospect of continuity due to high turnover in JEs. The JEs are among the phases of objectification and sedimentation and isomorphic characteristics, among JEs, are related to the sharing of best management practices.
