The present report proposes a central computing facility and presents the preliminary specifications for such a system. It is based, in part, on the results of earlier studies by two previous contractors on behalf of the U.S. Office of Education. The recommendations are based upon the present contractors considered evaluation of the earlier recommendations; of additional data obtained from both contractors and from educators in several institutions. Recommendations are given for systems, software, hardware, and operations requirements. Problem definition is discussed and estimated costs are given. It is concluded, as a result of this study, that the proposed central computing facility, for providing service to 50 schools with a total enrollment of 100,000 students, is feasible provided the recommended system concept is used.
