The Complex Trajectories project, a project funded by the Erasmus + program, aims to understand the increasingly diverse and complex trajectories of students at university, and to provide support to the people who go through them. It not only aims to guarantee inclusive access to university programs, but also success in carrying out studies regardless of the socioeconomic situation of the people who study them. The project plans to define a system for monitoring the trajectories of students that allows the development of support policies both institutional and of the university system and to define indicators to avoid dropping out. In this sense, it is proposed that the center of the analysis of the trajectories is not the program (graduation rates, etc.), but the student body. Thus, a trajectory will be considered successful regardless of whether there have been changes in studies or in the study modality.
