A model of the educational system in a typical public school was constructed within the theoretical framework of a general systems theory. The model is quantified and computerized so as to provide high speed simulation. Using the model developed, one can then simulate solutions to educational problems in seconds and at modest cost. The theory underlying the systems approach and the use of this approach in education are presented to provide a basic theoretical framework from which the model of the school can be examined. Then, the model is described and examples given which show how the model can be used to make decisions about allocation of resources for the system. The model is predicated on the belief that the basic components for the system (e.g., teachers, students) can be quantified. Since it is a logical model, not derived from empirical data, subjective decisions were required in the making of it. The next step will be to test the model. (JK)
