A Model That Combines IRT and Latent Class Models

A measurement model called Hybrid model is developed to overcome the weaknesses of the widely used Item Response Theory (IRT) and Latent Class models by combining them both. The weakness of IRT is that it is unable to express cognitive structure whether that is rule of operations or particular misunderstanding, or to give descriptive information of knowledge possessed by examinees. The Latent Class models require severe constraints, namely possession of complete knowledge of latent classes, and has the indeterminacy of number of ordered classes. The Hybrid model is most applicable in the so-called achievement testing, diagnostic testing, and mastery testing environment, and it is applicable even in some "ability tests" as long as a unique understanding or misunderstanding of the examinee can be characterized by a particular response pattern.
