A comparison of panel designs with routing methods in the multistage test with the partial credit model

In this study, we compared panel designs applied with various routing methods in the multistage test (MST) based on the partial credit model in the context of classification testing. Simulations were performed to compare three routing methods and four panel structures. Conditions of two test lengths and three passing rates were also included. The results showed that, regardless of the routing method used, the same panel structure performed similarly in terms of the precision of the classification decision with the same test length condition. The longer test length produced higher accuracy, whereas the 50 % passing rate yielded the lowest accuracy. Finally, all MST conditions performed well in terms of test security.
