Abstract

In the previous paper dealing with the same issue as this paper’s issue, we propose to use the known ability values from other testing results if the examinees are the same. In the follow-up program (FP) systems, we have been using three kinds of testing, the LCT (learning check testing), the CWT (collaborative work testing), and the FPT (follow-up program testing), in which the LCT provides accurate estimates for ability values. We used the LCT’s ability values in the CWT estimation. For stable estimation, we have used one-parameter estimation method (Rasch model) instead of two-parameter estimation method which is used in common. The estimation is performed well in the computation using one-year database. In this paper, we successively continue to estimate the item difficulties in a same manner but using three-year accumulated database of the LCT and the CWT access result.
