As opposed to traditional methods, this study is among the first ones that use Grey Relational Analysis method for evaluation of instructors' performances. The qualifications of an instructor in a higher educational institution is one of the top factors that directly affect the quality of education, and hence, the evaluation of instructors' performances is among the most significant indicators of quality control assurance. Even though the performance of an instructor is evaluated separately in similar studies as teaching performance and advising performance, this study handles these two together and calls it the performance of an instructor. To be able to evaluate the performance of the instructor, students of Marmara University Technical Sciences Vocational School Industrial Electronics department are surveyed. In the survey implemented, students are asked demographic questions in addition to the questions related to the performance of the instructor. In Grey relational analysis applied for assessment of the survey, the responses of the students are used instead of the frequency of the responses. The fact that its data set is limited and low in number; the variables are intermittent and composed of continuous random variables; can be applied in uncertain situations without necessitating a probability distribution; provides an ability to analyze one-to-one interrelations of data in a numerical manner with simple, specific and net calculation steps instead of a number of functional processes; contains no assumptions, and is easy to use and practical makes Grey relational analysis a method superior to others. Therefore, the data obtained as a result of the survey are assessed and the outcomes are interpreted with this new statistical method called Grey Relational Analysis.
