Co-production occurs when two or more institutions contribute funds and labor to many of the processes of making course components for distance teaching. This paper summarizes reasons for international co-production of multimedia distance teaching courses and provides a lengthy checklist of questions that should be considered before entering upon such co-production. These include: (1) processes by which institutions should seek partners for co-production; (2) criteria for selecting partners; (3) procedures for selection of content and media by co-producers; (4) criteria for selecting content and media; (5) factors that could raise the cost of the co-produced course above that of a course produced by a single institution; (6) bases for evaluating the co-production; and (7) the rights of each contributing institution in making decisions about the course and/or its marketing. The second half of the paper consists of a composite case study based on the Open University experience of international co-production. The paper concludes with three questions regarding the justification for and cost-effectiveness of attempting international co-production of courses. (JB)
