Assessment of fit of item response theory models: A critical review of the status quo and some future directions.

This paper provides a literature review of assessment of fit of item response theory models. Various types of fit procedures for item response theory models are reviewed, with a focus on their advantages and disadvantages. Real data examples are used to demonstrate some of the fit procedures. Recommendations are provided for researchers and practitioners who are interested in assessing the fit of item response theory models. [ABSTRACT FROM AUTHOR]
