This site contains support materials for ConQuest. The site is still under development, and resource materials will be added as they become available. The main purpose of this site, for the moment, is to be a repository for ConQuest resources.

ConQuest is a computer program for fitting item response models. The key distinction between ConQuest and other IRT programs is that ConQuest brings together in a single program a wide variety of item response models, including the dichotomous and polytomous one-parameter item response model, facets models that can be used to test for differential item functioning (DIF), multidimensional and latent regression models. In the next release of ConQuest, two-parameter item response models will be incorporated.
