In the current socioeconomic situation, the need to improve employability of potential workers is especially relevant. The aim of this study was to evaluate the efficacy of an intervention program focusing on improving employability of university students. To do this, a two-group study was designed: one group undertook the intervention program and the other group were used for comparison. Two measurements were taken at different times (pre-intervention and post-intervention). The sample consisted of 271 university students. The results show that the group that underwent the intervention program improved their perceived employability F(1, 269) = 17.49, p < .001; η2 = .06, openness to learning F(1, 269) = 4.24, p < .05; η2 = .02, self-efficacy for labor market insertion F(1, 269) = 75.70, p < .001; η2 = .22 and for teamwork F(1, 269) = 39.43, p < .001; η2 = .13, and their knowledge of employment resources F(1, 269) = 512.89, p < .001; η2 = .66 compared to the group that did not. Furthermore, there was a high level of satisfaction of participants with the intervention program.
