In developing nations, the decentralization of responsibilities relating to agriculture, irrigation, public health and sanitation, and small and large industry necessitates the training in public affairs for local government officials. They need training in policy forming and administrative roles as well as a reorientation of attitudes toward the role of local institutions; and subprofessionals should be trained to assist. This work is performed by universities, institutes of local government and other agencies; methods used include correspondence study, lectures, meetings with instructors, and teaching by itinerant training teams and visiting inspectors, who use methods similar to those used in educational institutions. Some personnel are sent to advanced countries for preparation for special posts. No organization or institution can do all the training needed and thousands of small units cannot provide more than a minimum, so local government must be expanded with the help of national governments.
