IRT-FIT: SAS® Macros for Fitting Item Response Theory (IRT) Models

Psychometrics has recently seen the development of complex measurement models to better represent test and item data. Item Response Theory (IRT), in particular, comprises a set of non-linear latent variable models that appear to have several conceptual and empirical properties that make them more valuable in practice than classical test theory methods. However, IRT-based models typically requir...

GOF OF IRT MODELS 1 Goodness of fit assessment of item response theory models

The article provides an overview of goodness of fit assessment methods for item response theory (IRT) models. It is now possible to obtain accurate p-values of the overall fit of the model if bivariate information statistics are used. Several alternative approaches are described. As the validity of inferences drawn on the fitted model depends on the magnitude of the misfit, if the model is reje...

Assessing IRT Model-Data Fit for Mixed Format Tests

This study examined various model combinations and calibration procedures for mixed format tests under different item response theory (IRT) models and calibration methods. Using real data sets that consist of both dichotomous and polytomous items, nine possibly applicable IRT model mixtures and two calibration procedures were compared based on traditional and alternative goodnessof-fit statisti...

Integrating IRT Analysis into LMS for Item Pool Optimization

Due to the computerization of assessment tests, the use of Item Response Theory (IRT) has become commonplace for educational assessment development, evaluation, and refinement. When used appropriately by a Learning Management System (LMS), IRT can improve the assessment quality, increase the efficiency of the testing process, and provide in-depth descriptions of item and test properties. This p...
