The first of five major sections included in the guide gives an overview of costs associated with providing education for handicapped students, discusses thirteen varieties of cost, and describes variables that can affect costs in educational settings. Section 2 focuses on decision matrices which allow judgements to be quantified for ease in choosing among alternatives. Specific topics addressed in section 2 include strengths and limitations of decision matrices, when to use decision matrices, materials and resources required, and how to implement a decision matrix. Focusing on cost benefit analysis and cost effectiveness analysis, the fourth section addresses how to determine the optimum allocation of resources in comparing alternate strategies for barrier removal. The final two sections of the guide describe the use of decision trees and simulations in strategy selection. The booklet contains self-instruction exercises. (LRA)
