Identifying and prioritizing performance evaluation indicators of high school principals in Tehran using fuzzy multi-criteria decision making approach

The aim of this study is to identify and weigh the performance evaluation indicators of high school principals in Tehran with a fuzzy multi-criteria decision making approach(MCDM). Improving the quality of education and achieving its goals and policies is achieved when there is an effective evaluation system with appropriate indicators. Since in real-life situations, experts 'judgments can not be expressed and interpreted as definite quantitative numbers, and data as well as definite numbers are insufficient to model real-world systems due to the uncertainty in decision makers' judgment, so this study relies on Fuzzy theory was performed. Research in handis applied in terms of purpose and descriptive in terms of data collection. The statistical population, drawn by using the Available Sampling method,, consists of 20 experts including 10 university professors and 10 senior managers of different education zones of Tehran. Both library and field methods were used to collect data. The research process regarding of weighting and ranking of indicators was performed by designing three questionnaires in 5 stages including fuzzy Delphi and fuzzy TOPSIS, best-worst, dimethyl and network analysis method.The results showed that using the fuzzy MCDM approach, the performance evaluation indicators of managers that were previously identified were ranked in relation to communication skills, personality traits, managerial skills, professional abilities and skills and decision making skills, respectively. The result is that the use of fuzzy multi-criteria methods provides more realistic results than quantitative or qualitative methods in empirical situations and is more feasible.
