China has made significant progress in increasing the quantity of heal
th workers in rural areas. Attention is shifting to improving the qual
ity of health workers. This article documents several features of heal
th workers in rural China. Many have not received formal training to a
level implied by their rank and title, and there is no clear relation
ship between the skills of health workers and the functions they perfo
rm. Many better-qualified personnel have left lower level health facil
ities for more attractive employment in higher level and urban facilit
ies. A system of professional licensing is currently being considered
that will link educational requirements to employment and promotion. T
his article outlines some of the issues that should be taken into cons
ideration in formulating this system. In particular, licensing may hav
e unequal impacts on rich and poorer areas. This article argues that o
ther regulatory measures will be necessary if licensing is to be an ef
fective mechanism for controlling the quality of health workers, and c
ontribute to the provision of affordable health services in both rich
and poor areas.
