This report delineates the data and the analytical procedures necessary for comparing educational demonstration programs. Used as a means of encouraging the introduction of new practices into the educational process, demonstration programs and their effectiveness depend, in part, on the quality of the data about the program and its availability to the planner. Data on demonstration programs are available within the demonstration districts, or in reports submitted by districts to State departments of education, or in reports submitted by the State departments of education on their own analyses of the programs. Data from all these sources should be consolidated into a single State evaluation report organized to facilitate analysis. The authors present a methodology for estimating program costs and determining program outcomes in a consistent and comparable manner. The use of cost effectiveness analysis in comparing costs and outcomes for alternative programs is discussed. (Author)
