Abstract, This study was conducted based on dual purposes; the first purpose was validation of the leadership creativity assessment scale from the perspective of teachers; the second purpose was to establish a qualification profile of the principals` leadership creativity using a standard tool. The current research applied a positivist epistemological orientation with a quantitative approach and evaluation method. The study population involved 1256 Sanandaj high school teachers of which 296 teachers (both males and female) were selected by stratified random sampling. In evaluating the validity of managerial creativity questionnaire factor analysis was used and in assessing its reliability of it, Cronbach’s alpha coefficient was applied to assess principles` of managerial creativity by teachers and the influence of demographic variables on teachers` assessment. Based on the findings of the study teachers evaluated their principals` level of Leadership creativity at a high level in their workplace.
