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 indice...

The score reliability of language performance tests has attracted increasing interest. Classical Test Theory cannot examine multiple sources of measurement error. Generalizability theory extends Classical Test Theory to provide a practical framework to identify and estimate multiple factors contributing to the total variance of measurement. Generalizability theory by using analysis of variance ...

The automated assembly of alternate test forms for online delivery provides an alternative to computer-administered, fixed test forms, or computerized-adaptive tests when a testing program migrates from paper/pencil testing to computer-based testing. The weighted deviations model (WDM) heuristic is particularly promising for automated test assembly (ATA) because it is computationally straightfo...
