Given the decline in political engagement among the electorate, especially among youth, there has been an effort to increase engagement through service-learning courses at both the high school and college levels. The research that exists regarding the effects of these courses on students is mixed. Some studies show that students become more civically engaged and increase their political efficacy, but these effects are found in courses tied specifically to politics. Other studies involving courses from other disciplines show no effect. Using a longitudinal study gathered at two points in time (when students enter their college career and are graduating), I show that students who take a service-learning course are more likely to engage politically (especially online) and report significantly higher levels of political efficacy. These results hold for students overall regardless of the subject of the course.
