Un modelo estructural para el análisis de los factores asociados a la elección de estudios universitarios

[EN] Access to the Spanish public university system is a complex process that involved administration, offering a certain number of places in different degrees that offer universities, and students, who must prioritize their preferences in a list. Determine what are the reasons that motivate a student, and their family and personal environment, to choose a particular degree and University to develop his studies, is a complex problem and that we have approached from the point of view of structural analysis. The aim of this work is to propose a partial multivariate model that can give an account of the weight of the different variables and identified factors involved in the decision about the choice of studies and University. The model we propose is specified based on a series of structural relationships involving a set of variables and context data, which we have grouped in the following factors: - Individual factors, associated with aspects related to student and personal interests, some academic and others clearly not. - Social factors, related with aspects that have to do with the social perception of the degree, their employability, the perception that we have of the University prestige, the degree, or the profession that gives access. - Context data, relative to the value of the access mark, the offer of seats or demand that has occurred in a certain degree and University in the years immediately prior to the taking of the decision. For this purpose a structural model and a questionnaire are proposed to evaluate the model, Model validation concludes with an extensive survey and analysis of the model results.
