Building on previous work on the civic returns of adult learning, this article examines the association between adult education, personality traits, and demands for civic participation or volunteering. Based on National Education Panel Study data, the study finds openness to be a crucial personality trait for participating in further training, as well as for civic participation, as it relates to competence and self-confidence in dealing with new demands. Extraversion is required for social interaction and communication with other participants. The study also shows that participants in further private training engage more at the management level of volunteering, where demands such as leadership and organizational talent are emphasized. The findings consider sociological factors such as the role of peers.
