The purpose of this study was to develop a rating scale that can be used to evaluate behavior patterns of the organization people pattern of preservice teachers (PSTs). By reviewing the related literature on people patterns, a preliminary scale of 38 items with a five-points Likert type was prepared. The number of items was reduced to 29 after obtaining expert opinions and was administered to 620 PSTs. As the results of the exploratory and confirmatory factor analysis, unlike two factors: structurist and free spirits behavior patterns, in the theory, we obtained the final scale of 15 items consisting of three factors: planners, solution-oriented and prescriptive behavior patterns. The related Cronbach Alpha value was found to be 0.830 for all the items. We identified that behavior patterns rating scale of the organization people pattern can be confidently applied to evaluate behavior patterns. Moreover, in this study, we obtained a contradiction between practice and theory. Thus, we provided a new idea related to behavior patterns of the organization people pattern.
