WebPrevious research has shown that testlet structures often violate important assumptions of dichotomous item response theory (D-IRT) models, applied to item-level scores, that can in turn affect the results of many measurement applications. In this situation, polytomous IRT (P-IRT) models, applied to testlet-level scores, have been used as an alternative. WebThe derivations of KR20 and α used continuous random variables for item scores (Sijtsma, 2009).
