This study was conducted to provide recommendations necessary for the implementation of a coordinated educational data processing system and to compare operational costs and selected resources in five public junior colleges in Illinois. Possible uses include: (1) identifying students served and services rendered, (2) determining costs for state appropriation requests, (3) developing sound techniques for managing expenditures at the state and local levels, (4) improving the allocation of costs between different programs, and (5) determining the location and number of programs. The system stresses the need for accurate source data identification, efficient data collection and processing, and a common data base for multi-agency use. (BH)
