Research Abstract	We investigated the generarization of the scoring rule method developed for the subjective probability measurements in order to the apply it for the educational tests. We showd new generalized scoring rule functions. We introduced also the sensibility and the potential of the scoring rule functions in order to evaluate the found scoring rule functions. It is theoretically shown that the previously found "sphere gain function" is the suitable scoring rule function in order to measure the subjective probability, homogeneously. We tried the scoring rule function at the educational test of the higher technology college. It is shown that the scoring rule method is acceped by the students and that many informations on the undestandings can be obtained by this methods. It is justfied that the number of the unconsidering answer is reduced by this method. We develped also the simplified scoring method for the educational tests. For the statistical treatment of the obtaind date by the scoring rule method, we developed the expended S-P diagram method and the fuzzuy graph methos.
