This study at a university in Slovakia asked two questions: (1) Does completion of a service-learning course lead to changes in students’ social and personal responsibility and their attitudes toward community service? (2) Are personal and social responsibility and attitudes toward community service correlated? Service-learning and the third mission of the university are almost unknown in Slovak higher education, and likewise no relevant test instruments adapted to Slovak conditions currently exist. Consequently, we adopted a scale from abroad—Conrad and Hedin’s (1981) Social and Personal Responsibility Scale (SPRS). We also used qualitative research methods. Compared to a control group, the service-learning students had statistically significant higher posttest scores in the Social Welfare, Duty, Performance of Responsible Acts, and Global Responsibility subscales. The research results revealed a need for new measuring tools that are sensitive to the specific context of service-learning implementation in Slovakia.
