One type of measurement often done in education are measurement of the students’ performance both for cognitive and effective aspects. These measures are extremely important therefore must use a good measuring tool and the results also easy to interpret. The measurement of students performance mostly use tests. Items response theory have evolved from traditional one to modern theories to apply more realistic models which are known as item response theory. However the use of modern test theory much rely on availability of the computer software. In this paper we report the development of a web-GUI interface that can be used to analyze polytomous responses, using Hierarchical Generalized Linear Models which will also contains theories and interpretations of the results. This web- GUI interface is expected to help teachers to understand and to do the analysis of polytomous responses more easily. 1. Introduction The development of the world of education today is progressing very rapidly, so that teachers must have adequate competence in every process of teaching and learning activities. Therefore the teacher is required to develop on himself so as to be able to carry out the teaching and learning process that is appropriate and varied from each teaching material. By having sufficient competence then a teacher is able to teach and evaluate well. It is not easy, therefore the teachers have a container called MGMP (Subject Teachers' Meeting) to help develop the existing teacher's kopentensi is no exception in Banyuwangi District. The MGMP function here is to accommodate teachers 'aspirations and teachers' difficulties in preparing and checking or testing good test items. Because the test item is very important as one measure of student ability. Preparation of tests performed starting from the design, assembly or manufacture and analysis of test items using various approaches, either using classical test theory or modern theory known as the grain response theory. Development of the test with the grain response theory approach has many advantages. The grain response theory model yields independent grain parameters of the test participants and test- participant parameters independent of the test set (Xitao, 1998). Since the logistics model is based on
