The purpose of this study is to explore the process of formation of a typification through total or average orientation in school evaluation and the theoretical basis of this typification formation in relation to behavioral economics. This study conducted an experimental study by applying the types of common and autonomous indicators used in the reality of school evaluation to joint and single evaluation. The results of the study confirmed the preference reversal phenomenon of the evaluator according to the evaluations with and without comparison. In the case of a single evaluation without comparison criteria, the evaluator evaluated that the less quantitatively, the more valuable. These results show that the attribute of the object is evaluated through the average rather than the sum of the evaluation elements. According to behavioral economics, it takes cognitive effort to find the sum in order to integrate and categorize the heterogeneity of the object to be evaluated, but the average can be easily inferred by an instant guess. In order to interact with others, our experience recognizes what is typical of the object. According to symbolic interactionism, what we perceive from objects is not a collection of sensory elements, but a universal characteristic of objects. If you put these two theories together, these suggest that the attributes of schools oriented to school evaluation are not the attributes of individualized school, but the attributes of schools culturally typical. This study suggests that social typification is established in a direction that is easily captured by representatives through standardization such as average and intuitive association without cognitive energy.
