Service-learning literature has been dominated by studies from North America with little cross-national comparative work. This article reports on a survey of university students conducted across 14 different countries. The study examines the relationships between service-learning programs (both compulsory and optional) at high school and university, along with current volunteering, study subject, and sociodemographic variables. The survey found variation in service-learning across the different countries along with relationships between service-learning participation and gender, family income, and study subject. By contrast to previous research, however, both mandatory and optional service-learning at high school and university led to higher participation in general volunteering.
