The purpose of this study is to specify the mission that the education experts consider as preferential by providing a pair-wise comparison of their missions. The study group includes 174 education supervisors who are on duty in the primary school section of 56 different provinces. “Evaluation Form of Education Supervisors’ Mission Priorities” has been used as the data collection tool. Evaluation form of education supervisors’ mission priorities were scaled from complete data matrix with Thurstone’s law of comparative judgment case V. Equation. After the scaling operation, the inner consistency of supervisor judgments, the extent of agreement among supervisors and the significance of these were examined. For this process, two statistics called Kendall’s zeta statistics and Kendall’s U statistics were used. The results of this study have revealed that “counseling and in service training” is considered as a primary mission by education supervisors. Guidance and on site training is followed by “inspection and evaluation”, “research”, and lastly “inquisition”. In addition, the education supervisor can be considered as consistent in her/his judgment and the education supervisors’ judgments are considered in agreement.Key words: The education supervisor, supervision, scaling
