WebJul 21, 2024 · The equating process aims to provide comparable test scores. This talk focuses on Item Response Theory (IRT) methods for dichotomous items. In IRT models, … Webdesign are also compared to "no equating.11 In "no equating," the raw-to- scaled score conversion table is constructed under the assumption that the conversion table on a new form is identical to that for a given old form. Equipercentile and three-parameter logistic item response theory (IRT) equating methods are compared for both designs.
