ABSTRACT In recent decades, the interest of theorists and researchers in emotional intelligence has increased at times compared to that in IQ. Theoretical work has hypothesized that emotional intelligence is more than just cognitive intelligence and is likely measured by methods other than those that consider only IQ. Different authors impose and defend different concepts related to the understanding and study of emotional intelligence. This article presents the time-established, theoretically-based instruments for measuring emotional intelligence level as well as other popular instruments. The theoretical review of the models is not touched upon, but the emphasis is on the questionnaires measuring emotional intelligence and the comparison between them.
