Disadvantages Of Item Response Theory

Disadvantages Of Item Response Theory. Item response theory (irt) and related latent variable models represent modern psychometric theory, the successor to classical test theory in psychological assessment. An essential feature of these models is parameter separation, that is, the influences of the items and persons on the responses are modeled by distinct sets of parameters.
