The major aim of this study is to devise a model for rationalizing sports policies by defining the basic concepts that should be inherent in any proper sports policy despite the infinite diversity that characterizes actual sport situations. The first part of the study discusses three concepts which are basic to the model: a) the "level of sport" which denotes the overall objectives of sports policy; b) the "sports situation" which is the reality of sport as it is defined by the people, facilities, and organizations involved in all areas of sport and as it is limited by extra-sports elements, which include demographic, climatic, geographical, economic, and sociological conditions and the physical and anatomical characteristics of the population; and c) "development factors," or those activities which, when combined in programs, have the effect of improving the existing "level of sport." Part two of the study is a mathematical outline of a model for decision making with regard to rationalizing sport policy. Part three of the study contains the statistical instruments for implementing the mathematical model. (HMD)
