When youth are involved in their communities, they typically do so through institutional structures. We construe youth service as a type of long-term, intensive volunteerism or civic service, which takes a range of institutional forms including service-learning, national service, and international service. We define these forms as having common operational features, and summarize what is known about them and their effects on youth and the individuals and communities with whom the youth are engaged. We identify directions for future research, including issues of server inclusion and impacts on the served.
