5 Abstract The theoretical part of the paper focuses on computerized adaptive testing (CAT) and item response theory (IRT). Also included is a chapter comparing IRT with the commonly used classical test theory (CTT). There is also a brief mention of computerized and online testing, as these types of administration differ in many aspects from conventional paper & pencil tests. The goal of this paper was to evaluate the individual ways of eEPI test administration and to compare them with eEPQ tests and self-evaluation. In the practical part the items of the extraversion scale of the Eysenck Personality Inventory (eEPI) were calibrated using a group of 124 respondents. The acquired data were subsequently used to carry out a simulation of computerized adaptive testing, which clearly demonstrated the benefits of this type of testing in comparison to the classical test form. These results were compared with the results of real CAT test administration using the original sample and a new group of respondents (Np=69, Nn=68). The results were highly correlated with the results of the simulated test. Moreover, to verify the validity of the computerized adaptive version of eEOD, the respondents' results in this test were compared with the results in the eEPQ test and in a short self-assessment scale.
