Active and democratic citizenship promotion has become a critical challenge for higher education, and civic engagement is a fundamental axis not only in education but also in fostering democratic systems. Consequently, teacher educators held a prominent role through their own teaching practices to generate contexts promoting critical thinking, skills and attitudes. The aim of this study was to analyze the learning related to the political dimension developed by pre-service teachers (n = 123) after participating in a Service-Learning program through physical education with children at risk or/and student with educational needs. This research followed a qualitative research approach and we based the analysis of reflective diaries on Gorham’s (2005) categories regarding political learning: Critical political thinking, Interest in politics, Deliberation and Political judgment. The findings show a development in learning such as civic attitudes, critical political thinking, awareness of social justice problems, increased civic compromise and responsibility. The Service-Learning program, therefore, may have been an adequate option to develop pre-service teachers’ learning related to a political perspective. Therefore, these findings let us understand how Service-Learning may foster equity and social justice among future teachers.
