Abstract

Results of the survey, conducted using Joy Guilford methodology, of 800 servicemen regarding their professional competence was analyzed with IRT models. In particular, Rasch model and 1-PL, 2-PL and 3-PL models were used. All computations were performed with R statistical software along with ltm package. Latent parameters for both respondents and corresponding indicators (survey questions) were obtained. It was found that there exists signifi cant discrepancy between the models and results of the survey. Analysis of this discrepancy has shown that the major cause of their existence are inadequate conditions under which the survey was conducted.
