Community coalitions are prominent mechanisms for building local capac
ities to address health and social concerns. Although there are case s
tudies and descriptive reports on coalitions, there is little empirica
l information about coalition process and outcome. This paper describe
s a case study using a methodology for monitoring and evaluating commu
nity health coalitions. Data are fed back to coalition leaders and mem
bers, funding agents, and other relevant audiences as part of the deve
lopment process. The monitoring system provides data on eight key meas
ures of coalition process and outcome: the number of members, planning
products, financial resources generated, dollars obtained, volunteers
recruited, services provided, community actions and community changes
. Illustrative data are presented for two different community health c
oalitions. Finally, challenges and opportunities in evaluating communi
ty coalitions are discussed.
