A feasibility analysis of a single integrated central computer system for secondary schools and junior colleges finds that a central computing facility capable of serving 50 schools with a total enrollment of 100,000 students is feasible at a cost of $18 per student per year. The recommended system is a multiprogrammed-batch operation. Preliminary specifications are given for the system's objectives, costs, capacity, flexibility, and growth capability and for alternative types of software, hardware, formats, and compilers. Benefits of the specified system are discussed with respect to educational values, vocational training values, and administrative applications. Twenty-one appendices analyze in detail aspects of the proposed system and present supporting information and data. (TT)
