The development of moral reasoning and decision-making constitutes a central component of contemporary higher education. This study aimed to determine the effect of an ethics training program on moral decision-making among school students. A quasi-experimental design with a non-equivalent control group was employed, using pretest and posttest measures to assess changes in moral reasoning, moral judgment, and ethical dilemma resolution. The sample consisted of students assigned to an experimental group, which received the intervention, and a control group that followed the regular curriculum. Results showed statistically significant posttest differences in favor of the experimental group, with improvements across the evaluated dimensions. The effect size suggests a moderate impact of the program on moral decision-making. It is concluded that the systematic implementation of structured ethics training can strengthen moral competencies in higher education contexts. These findings provide empirical evidence to support curriculum design aimed at students' integral development and highlight the importance of incorporating structured ethics programs in high school education.
