It is widely used in the fields of measurement, psychometrics, and educational assessment. This paper introduces ConQuest’s functions, the analysis models fitted, and its applications. An analysis example is shown for investigating psychometric properties of a psychological instrument with a multidimensional item response theory (MIRT) model.
