A computer-based version and a manual version of a set of techniques (EA008632-633) developed to assist in forecasting the need for primary and secondary school facilities and in critically evaluating proposals to satisfy that need are evaluated in this report. The report is organized into eight chapters. Chapter 1 summarizes the project organization, staffing, methodology, and final products. Chapter 2 reviews the general level of school facility planning in the United States, based on a survey of literature, school district interviews, and local and state questionnaires. Chapters 3 through 6 examine the four basic components of the system. Each chapter describes the techniques that have been developed during the project in light of the particular planning problem, and other relevant research activity. Chapter 7 summarizes different procedures for using the system, with emphasis on techniques for recognizing and appreciating "uncertainty." The final chapter summarizes initial responses to the system based on a preliminary evaluation by various school administrators. (Author/MLF)
