ABSTRACT In the current trend of dwindling number of students in a class, educational assessment method is required to be flexible in evaluating such as possible to handle the small samples as well as the large samples to create the unity in all cases. The purpose of this paper is to propose a new assessment method which is based on combining Grey Student Problem chart and Rasch GSP method to evaluate the question difficulty and student ability in the test. This method utilized the advantages of two mentioned model to create the creative evaluation based on the arrangement in order of statistical data according to priority criteria. The results processed by this method have been compared with results processed by previous model, the Item Response Theory oneparameter logistic, to determine the suitability of method. This comparison result showed that the fit between two methods was high, moreover, the advantage of proposed method was simple and easy to apply. Especially, it was not only best for handling small samples but also applicable for large samples. This proposed method is a more convenient way for educators to perform the evaluation process after a teaching stage. Keywords: Grey Student Problem; question difficulty; student ability; small sample; large sample
