초록

The purpose of this study is to introduce a standard setting method based on cluster analysis, the Bookmark Method, and Item Response Theory, especially the Rasch measurement model. In proposing the use of cluster analysis to facilitate a standard setting, although there are several types of cluster analysis methods, the standard setting is related essentially a classification. That is, using cluster analysis to facilitate a standard setting involves grouping test takers into discrete clusters based on their responses to test items. This method has theoretical appeal because it models the discrete nature of a standard setting. The Bookmark Method was developed to be used with tests that are scored using Item Response Theory. I also explained the procedures such as? how to set the cut-score using Bookmark method. Lastly, I introduce standard setting method using the Rasch measurement theory. For its successful implementation, some suggestions were discussed and implications were given.
