This report evaluates and expands a database on statewide articulation and transfer agreements, and provides an updated taxonomy of types of agreements. Initial sections outline the purpose and procedures of the articulation study. Next, a taxonomy of statewide agreements is presented for the years 1972, 1976, and 1985. The agreements are categorized as belonging to one of four types: formal and legally-based guidelines and policies; state system policies; voluntary agreements between institutions or within states; and states specializing in vocational-technical credit transfer. Following a historical overview of statewide articulation and transfer efforts, the paper presents summaries of developments in the following target states: Arizona, California, Florida, Hawaii, Illinois, Massachusetts, New Jersey, New York, North Carolina, Oklahoma, Oregon, Pennsylvania, Washington, and Wyoming. Finally, concluding comments discuss the significance of the results. (LAL)
