An Application of Bi-factor MIRT Model to MST with Intersectional Routing

• In Event: Electronic Board Session IV

Abstract

This study investigates the effectiveness of intersectional routing (ISR), with bi-factor MIRT model for mixed-format MST composed of MC and FR items. Simulation results show that ISR holds potential as an effective approach for accurate ability estimation, especially when test length is short and correlation between sections are high.
