Comparing Panel Designs With Routing Methods in the Multistage Test With the Partial Credit Model

• In Event: Issues of Rasch Dimensionality, Scaling, and Fit

Abstract

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