This report discusses briefly the concept of open education and its application at the college and university level. Efforts already underway in the United States and abroad are covered in two appendices. Four models of open universities are described in some detail. One model is based on the extension of community college activities. The second model assumes a close relationship with one or more four-year institutions. The third model is based on a nationwide network of relatively independent neighborhood learning centers, and the fourth model is an elaboration of existing efforts to provide postgraduate professional education by television lessons. Each model is broken into four component systems: a learner access system, a distribution system, a production-procurement-storage system, and a credentialling system. In addition to model descriptions, seven recommendations are proposed as steps that can expedite the growth of open universities in the United States. (Author)
