Program evaluation is integral to the policy analysis process in socia

ons about client services. This article examines the role of program e

suggests that program evaluation is most persuasive as a component of
the policy process when its role is clearly understood. Such clarity
can be achieved by using the program mandate to guide evaluation activ
ity and including frontline practitioners in developing program evalua
tion models.
