This study is an attempt to overcome the weaknesses. This study aims to produce a polytomous scoring model for responses to multiple true-false butirs in order to get a more accurate estimation of abilities in physics. It adopts the Four-D model and its accuracy is assessed through empirical and simulation studies. The empirical study employed 15 multiple true-false butirs taken from the New Students Entrance Test of State University the year of 19962006. It administered to 410 new students enrolled in 2007 of Faculty of Mathematics and Science of Surabaya State University. The testees responses were scored using the partial credit model (PCM) I; II; and III and also dichotomously scored. The results of the four scoring models were analyzed using the Quest program to obtain the estimation of the butir difficulty level () and that of the testees abilities (). The generating of the simulation data used the SAS statistical program and the estimation accuracy was analyzed by using the root mean squared error (RMSE) method. The results of the study show the following: (i) The scoring with the partial credit model with weighting is capable of estimating abilities more accurate than without weighting and dichotomous scoring; (ii) The more the number of the categories in the partial credit scoring is, the more accurate the result of the ability estimation.
