Older people's civic participation contributes to community development while at the same time providing opportunities for personal growth in later life. One important dimension of civic participation that has been largely underexplored is informal learning. The aim of this study is to explore the learnings experienced by Spanish older people through their participation in political organizations as one important type of participation that has received little attention in the literature to date. A total of 192 people aged 65 years and older and actively engaged in three kinds of political organizations participated in the study. Participants answered an open-ended question regarding learnings through political participation. Results show a range of informal learnings, relating to social, political, or instrumental domains. Both the type of organization and some sociodemographic and participatory characteristics are associated with the type of learnings experienced by participants. Implications for political organizations are discussed.
