Classical test theory vs. item response theory: An evaluation of the theory test in the Swedish driving-license test
2004 (English)Report (Other academic)
The Swedish driving-license test consists of a theory test and a practical road test. The aim of this paper is to evaluate which Item Response Theory (IRT) model among the one (1PL), two (2PL) and three (3PL) parameter logistic IRT models that is the most suitable to use when evaluating the theory test in the Swedish driving-license test. Further, to compare the chosen IRT model with the indices in Classical Test Theory (CTT). The theory test has 65 multiple-choice items and is criterionreferenced. The evaluation of the models were made by verifying the assumptions that IRT models rely on, examining the expected model features and evaluating how well the models predict actual test results. The overall conclusion from this evaluation is that 3PL model is preferable to use when evaluating the theory test. By comparing the indices from CTT and IRT it was concluded that both give valuable information and should be included in an analysis of the theory test in the Swedish driving-license test.
