Service learning has been proposed as a way for universities to expose unde
rgraduate and graduate students to ethnically and socially diverse populati
ons while engaging them in constructive community-based activities. In Wash
ington, D.C., several academic medical centers initiated service-learning p
rograms that placed health professions students in community clinics servin
g the uninsured. In this article, the authors explore the impact of these p
rograms on the clinics and their communities. A project initiated by George
Washington University failed because the health center was unwilling to re
spond to community needs. A more encouraging model exists in Howard Univers
ity's efforts to expand services to uninsured Hispanic patients through par
tnership with a free clinic serving the Hispanic community. The authors con
clude that service-learning programs based in underserved communities are m
ost likely to succeed in the context of a full-scale institutional commitme
nt to the health of the target population.
