A model is described that can be used to establish postsecondary cooperative internship programs or improve existing programs to bring vocational education and business together. Following an introduction that includes definitions of terms, chapter 2 defines an internship program. Chapters 3-12 discuss the 10 procedures/components involved in the model for a cooperative internship program. They are organizing an advisory committee, planning an internship program, implementing an internship program, promoting an internship program, enrolling students in the internship program, developing the internship agency, placing interns on the job, developing training plans, supervising interns, and evaluating interns. A discussion of vocational-technical school internships follows that focuses on the model components. Appendixes, amounting to approximately one-half of the document, include general forms and student forms for internship. An attachment is the final report of the project that developed the model internship program. Sections of the report consider project objectives, procedures, findings, evaluation, and conclusions and recommendations. (YLB)
