[login to view URL] was the reason for using IRT in this article? [login to view URL] did the author/s go about using IRT? Give details such as the type of model, calibration, the scores that were obtained, etc. [login to view URL] conclusions were drawn from the IRT analysis? Include a statement concerning how the IRT analysis enabled the researcher/s to answer the research questions.
