Case studies were made of the cost and efficient utilization of resources for inservice education and training of teachers (INSET) in England, Australia, the United States, Denmark, Sweden, and France. The studies were prepared on the basis of four main topics: (1) analysis of costs; (2) efficient or full utilization of resources; (3) financing; and (4) organization and planning. This report covers these four topics and examines the links between them. National, local, and programmatic costs are examined as well as how the cost burden is distributed among participants. The problems of conflict and collaboration in INSET planning are explored. Factual data on costs, finance, and planning for each of the six countries studied in this project are summarized in the appendix. (JD)
