The decision is omnipresent in human existence. In many cases, it even engages the remains of an existence. This research emphasizes the link between information and communication, which are related to the commitment and the resulting decision. The research shows that the decision is constrained by information characterizing the situation and elements which are provided by knowledge. Its experimental framework concerns students, who are bound to choose faculties and universities – a decision relatively difficult to be taken in Lebanon, an atypical country quite complex and influenced by religion and geopolitical situation.The main objective of this thesis is to present an exploratory study in order to characterize the major factors which determine the students’ decision-making. Based on the information as it is projected into the documentary presentation, it literally focuses on the study of mediation between university and a future high school candidate in a decision-making framework. The study discusses the experiences of students in their first academic year, so they have already made their decision; it establishes links between the theory of commitment and decision-making. It also seeks to define links between information built from a document, decision-making and decision support. The originality of this research lies in the implementation of a method of listening to the needs and hierarchy of needs, developed by DeVisU laboratory at the University of Valenciennes, based on the intersection and as a complement for qualitative and quantitative methods.The main contribution of this research is to reveal which characteristics of academic institutions outweigh the decision of students. As a result of national and international competition, most universities treat their attractiveness and are forced to develop new recruitment strategies. The challenge is to retain the best students. Thus, for the population being studied, it is not knowledge but preparation of labor market that matters most. In addition to that, and in contrast to received wisdom, it is human mediation that has the power to create an engaging communication and in any case, the documentation systems, even of advanced technology.
