The authors describe the advantages and disadvantages of central gover
nance of the undergraduate medical curriculum as contrasted with tradi
tional departmental approaches, based upon their schools's experience
with a new, centrally governed curriculum during the preceding four ye
ars. Central governance has more advantages, but also more costs, comp
ared with traditional departmental approaches. Central governance does
what it was intended to do: it provides rational and integrative mech
anisms for ensuring a broad general education in medicine focusing on
the doctor-patient relationship. It also provides an effective mechani
sm for dealing with ''turf'' and time issues in the curriculum while a
llowing for and encouraging changes and providing mechanisms for evalu
ating those changes. However, as the allocation of resources and rewar
ds remains more departmentally than centrally based, a major challenge
of central governance has been to help faculty resolve a ''conflict o
f loyalty'' (the sense of serving two masters) between school and depa
rtment, particularly in the evaluation and reward of teaching. On bala
nce, central governance provides a powerful means of introducing broad
-based reforms into all elements of the undergraduate medical curricul
um, but it requires ongoing collaboration with faculty and chairs to a
ssist them in negotiating competing pressures and priorities as they s
trive to become excellent teachers.
