The need for employment training delivery systems to work cooperatively in preparing a trained work force is described. A brief review of the literature lists seven major employment training delivery systems which operate independently of each other; discusses the problems associated with their lack of cooperation; and argues that cooperation among these systems is essential at this time. The delivery systems listed are: the military, the Job Training Partnership Act, business and industry, apprenticeship, universities, public vocational education, and proprietary or independent schools. Five major principles which should be incorporated into cooperative programs are presented along with examples of procedures for achieving each principle. The principles, which were identified by a questionnaire survey of representatives of the seven major delivery systems, are: (1) reduce competition and encourage cooperation among the providers of employment training; (2) ensure the quality and relevance of employment training; (3) ensure that employment training programs are accessible and available; (4) increase the efficiency of employment training; and (5) ensure ongoing planning and evaluation of the employment training system and its components.
