This study examines the impact of an experiential service-learning project designed to help high school students begin to choose a career path and increase college students' understanding about how to make career decisions. In the study, two groups of college students attended information sessions on career advising. The first group then helped provide career information to high school students as part of a service project in a college class. The second group did not help provide career information to high school students. Posttest comparisons of the two groups of college students indicated that college students who participated in the service project showed significantly more understanding of career decision-making than students who had not participated in the service project.
