A project explored less costly methods by which educational planning and control information could be collected, organized, and disseminated to appropriate planners and policymakers. An existing prototype computer simulation was refined and further developed by incorporating into it additional demographic, manpower, educational, and economic data by modifying it to accommodate additional variables and parameters, and by experimenting with various model computer simulation runs to provide a range of outputs and thus test the reasonableness and validity of the model for planning and policymaking purposes. The project result, Rhode Island Model II (RIM II) constitutes (1) a common demographic, manpower, and educational data base for dissemination and use by planners and policymakers and various levels in different State and local agencies; (2) a process and mechanism for improving communication and coordinating the efforts of State agencies involved in meeting occupation and training needs of the State's population, and (3) an analytic and planning tool to assist the Department of Education in analyzing the impact of different demographic and economic contingencies in the State's educational system and assess the consequences of alternative educational policies. RIM II is composed of five sectors dealing with the State population, labor market, student enrollments, educational costs, and educational benefits. These can be operated and analyzed separately or together. On the basis of data collected from a variety of sources, RIM II has been shown to successfully reconstruct the behavior of the system from 1960 to the present. It also extrapolates the behavior of the system into the future. It is recommended that RIM II be fully implemented within the State through model runs based on available data. (LAS)
