| Outline of Final Research Achievements |
In this study, we developed e-testing system for practitioners. At first, based on polytomous item response theory model, we derived order preserving statistics and approximated Bayesian estimator. We also proposed some selection methods for equating. From these theoretical results, we developed e-testing system including simplified item bank. This system was evaluated some real datasets.
