Higher education is increasingly oriented towards educating in values, based on the acquisition of practical skills. This has led to the development of active methodologies which complement theory-based learning and classroom lectures. Service-learning integrates ethical and social commitment by applying previously acquired skills and knowledge in real-life situations. This study aims to analyse the self-perception of transversals skills among students of business administration through a service-learning and the possible influence of gender. A questionnaire comprising 57 variables using a Likert scale was administered to a sample of 210 students, the data were analysed, and statistic significance tests were carried out. The results suggest there is a positive relationship between participation in the service-learning activity and the level of skill, especially for ethical and social skills, with significant differences by gender. This work aims to contribute to the consolidation of service-learning as a tool for the acquisition of ethical and social skills at universities, which is so important for future managers of companies and organisations.
