As devolution of responsibilities from higher-level governments to lower-le
vel governments and nonprofits continues, more and more attention will be f
ocused on implementation, specifically on how to convince reluctant partner
s to participate fully in program success. In spite of a considerable body
of research on implementation, few systematic efforts have been made to exa
mine the predictors of successful compliance. This article provides such an
effort, examining five possible predictors to implementation of primary ca
re mandates in seven states. Among key factors in successful implementation
of these mandates were legislative funding targeted to the program and pro
active leadership within the medical schools. Monitoring and oversight were
in place in only one state where implementation was judged to have been mo
st successful. The wording of the legislative mandate and communication-oft
en touted as important elements of successful implementation-were not impor
tant in these seven states.
