Background and Study Aim. Research on moral competency in sports is rare, and findings are inconsistent. These findings point to moral development as a multifaceted and complex process. This process is mediated by various life situations and dilemma choices. Sport can play a crucial role in this area with its often ‘role-taking’ experience and confrontations with personal moral standards. This study aimed to analyze the relationship of competency levels and sport experience across different sports. Material and Methods. A sample of university students in sport-related faculties (N = 947) was assessed with the use of Moral Competence test (MCT). The group was divided into 11 predetermined types of sports, training modes (amateur/professional), and indicated years of training practice. Results. The general moral competency level in the overall researched sample of students was low, but similar to their peer-age reference groups found in relevant literature. The findings indicated some differences in moral competency levels between amateurs and professionals. Amateurs showed a higher competency levels in five types of sports (non-invasion games, martial arts/fighting sports, aquatic boating sports). In contrast, professionals showed a higher competency level in dance sports. The only positive, moderate correlation between years of training and moral competency level was found with professional athletes in aquatic boating sports: the longer they trained, the higher their moral competency level was. Conclusions. These results offer new insight into the impact of sports on moral development and can act as a solid foundation for further in-depth research in this area.
