This report proposes a model for designing decision-making information systems in education. In the first section, several relevant themes in education and data processing are summarized, including user involvement, team effort, decision orientation, indicators, enabling technology, design methodologies, and process rather than product. The six steps in the design model are described in the next section: (1) needs assessment; (2) feasibility study; (3) conceptual design; (4) physical design; (5) implementation; and (6) evolution. The third section is a case study showing the application of the model to the design of a microcomputer database that would track referrals in the Portland (Oregon) Public Schools Alcohol and Drug Program.
