Educational work in student sports is aimed at developing students’ competencies of personal and collective responsibility for the quality of self-realization in life. Integration of standards of professional, educational and sports activities in terms of goal setting ensures the achievement of personal results of participants of student sports clubs. The protection of the rights of student-athletes in the mediation (reconciliation) service implements educational and regulatory functions and justifies its necessity. The attitude to mediation as a way of settling disputes on the implementation of the rights of student-athletes justifies the expediency of the mediation service. The survey of participants and staff of the student club of the Higher School of Physical Culture and Sports of the Immanuel Kant Baltic Federal University (N = 61) proved the relevance of the problem of protecting the rights of student-athletes to participate in competitions and be admitted to sports teams (83.7%); the presence of competence deficits in sports ethics (78.7%); willingness to resolve a conflict with the leaders of a sports club and a sports team in the mediation service on the issue of sports sanctions for misconduct (73.8%); acceptance of mediation as a way to develop and conclude a mutually beneficial solution (93.4%); the likelihood of contractual capacity in conflict resolution based on a common interest in honest, fair play (95.1%); balance as an essential personality trait of the sports mediator (93.4%). The survey data determine the recommendations for the organization of mediation services in the sports student club: the structure of the educational work of the club; humanitarian service of legal protection and psychological support of the club members and employees; standardization of documentation, regulatory and methodological support of the club’s activities; regulation of friendly dispute resolution on the implementation of the rights of student-athletes.
