Since facilities and technology are useless without trained people, policies that address manpower training must be an integral part of a plan for the use of science and technology in national development. Presented is an overview of labor force requirements, educational needs, and other considerations related to industrial and agricultural development and enhancement of the quality of life in developing countries. Among the topics covered are manpower supply and demand, the effectiveness of training institutions, the role of multinational agencies, and the "brain drain" to developed nations. Descriptions of problems and procedures in Asia, Africa, and Latin America augment the summary judgments which appear. Policy implications, with emphasis on United States development assistance programs, conclude the report. (Author/WB)
