This paper considers selected aspects of the systems analysis of administrative decisionmaking regarding resource allocations in an educational system. A model of the instructional materials purchase system is presented. The major components of this model are: environment, input, decision process, conversion structure, conversion process, output, and feedback. The results of applying this model to some findings of a study of resource allocation in a small urban school system are discussed. Some persons responsible for initiating purchase orders were sent questionnaires in order to collect data on (1) type of material purchased, (2) who makes the purchase decision, (3) factors influencing the decision, and (4) timing of the decision. The findings indicate that, given the constraints of budget, facilities, personnel, and time, the system is operating with a fair degree of efficiency in meeting the demands of the curriculum.
