Organised and sponsored by the U.N. Public Administration Division, this intercontinental seminar dealt with problems related to the development of senior administrators in the public service of the developing countries. The 37 participants were either leading civil servants or heads of training institutions in Africa, Asia, and Latin America; in addition there were observers from the advanced countries and the specialised agencies of the United States. The seminar's four working groups met regularly in the afternoons to explore in depth the topics discussed at the morning plenary sessions. These included: the definition of the senior administrator and the delineation of his responsibilities; the identification of his developmental needs; the personnel system under which he operates; the institutional arrangements for the development of his administrative potentialities; and the evaluation of the methods and techniques designed to achieve these objectives.
