This article examines whether the motive behind community service performed during high school--either voluntary or required--influences engagement in volunteer work during the young adult years. Using a sample of students from the National Education Longitudinal Study of 1988 (N = 9,966), service work in high school is linked with community service in young adulthood. The findings show that participation in community service declines substantially in the 2 years following high school graduation but then rebounds slightly once members of the sample reach their mid-20s. In general, community service participation in high school was related to volunteer work both 2 and 8 years after high school graduation. However, those who were required to participate in community service while in high school were only able to sustain involvement 8 years after graduation if they reported that their participation was voluntary. Strengths and limitations of the analysis as well as implications for youth policy are discussed. (Contains 3 tables and 5 notes.)
