A new phenomenon in American education is the working relationship of "high school partnerships." These committments between a corporation and an urban school pledge cooperation over a period of years in an organized group of projects intended to improve education and benefit the students. To determine the problems, risks, and potentials of high school partnership programs, representatives of 10 partnership programs were interviewed and completed questionnaires. Although it is too soon to expect conclusive evaluation of the partnership programs, some patterns have emerged which should prove valuable to future associations. This report covers: (1) history of the cooperative school, (2) what partnerships are, (3) what happens to a partnership, (4) how to start a partnership, (5) evaluation of program, and (6) some preliminary conclusions. A summary of projects in 30 partnerships, catalog of companies and schools, a company's agreement, a partnership plan, methods of study, an interview guide, and a sample questionnaire are appended.
