Abstract | This article investigates how measurement models and statistical procedures can be applied to estimate the accuracy of proficiency classification in language testing. The paper starts with a concise introduction of four measurement models: the classical test theory (CTT) model, the dichotomous item response theory (IRT) model, the testlet response theory (TRT) model, and the polytomous item response theory (Poly-IRT) model. Following this, two classification procedures are presented: the Livingston and Lewis method for CTT and the Rudner method for the three IRT-based models. The utility of these models and procedures are then evaluated by examining the accuracy of classifying 5000 language test takers from a large-scale language certification examination into two proficiency categories. (Contains 7 tables and 4 figures.) (As Provided). |
