The recent complexity of the university system, with diverse academic trajectories and varying socio-demographic characteristics of students, has led to increased access for historically underrepresented students. This has resulted in a rising number of adult learners, students with external responsibilities and individuals returning to education. However, despite this enhanced access, it remains unclear whether it has improved graduation. This uncertainty stems from the fact that students' social circumstances and external responsibilities differ significantly based on when they enter university. From a life course perspective, the aim of this paper is to explore the interactive effects of age at university entrance and employment status on the probability of graduating of an entire cohort of new students who entered the Catalan Higher Education System in 2012 (N = 29,463). The results show an interaction effect between age and employment status on the probability of graduation where working decreases the probability of graduation among students younger than 42 years old. Conversely, the negative impact of employment on university graduation diminishes among students entering university at an older age. This underscores the importance of adopting a life course perspective to comprehend students' educational experiences and outcomes within higher education.
