2.1. Student Persistence Patterns and Attrition Dynamics Across Tracks
The theoretical and empirical analysis of student trajectories across undergraduate pathways indicates that persistence dynamics operate through complex interactions between prior secondary schooling and institutional structures. Within general university tracks, survival analysis reveals that student dropout constitutes an evolving process characterized by distinct temporal stages, with vocational secondary graduates facing elevated attrition risks across both short and long horizons (crossref-10-4000-13j6d, 2025). This sustained vulnerability highlights how secondary academic preparation conditions the probability of remaining enrolled within general university curricula. Concurrently, institutional support policies aimed at reducing early university selection and academic failure produce differentiated outcomes across student profiles, as generalized pedagogical interventions fail to uniformly alleviate disparities for non-scientific cohorts (crossref-10-3917-cdle-038-0175, 2014). Alongside attrition, educational reorientation represents a critical trajectory bifurcation that functions as a structural adaptation rather than pure academic departure (crossref-10-4000-14rwn, 2025). Empirical evidence establishes that examination behaviors and academic results strongly distinguish reorienting students from non-reorienting peers, yet academically endowed students preserve significantly greater opportunities to execute purposeful reorientations when encountering initial difficulties (crossref-10-4000-14rwn, 2025). Consequently, the contrast between professionalized technological pathways and general licence tracks underscores that integrated pedagogical supervision provides essential scaffolding against early dropout, whereas general academic tracks demand high institutional autonomy that magnifies initial social and educational inequalities. These dynamics demonstrate that graduate employability and persistence fundamentally depend upon early structural alignment between curricular demands and incoming student competencies.
