There are many self-report measures of EI, including the EQ-i, the Swinburne University Emotional Intelligence Test (SUEIT), and the Schutte EI model. None of these assess intelligence, abilities, or skills (as their authors often claim), but rather, they are limited measures of trait emotional intelligence. The most widely used and widely researched measure of self-report or self-schema (as it is currently referred to) emotional intelligence is the EQ-i 2.0. Originally known as the BarOn EQ-i, it was the first self-report measure of emotional intelligence available, the only measure predating Goleman's best-selling book. There are over 200 studies that have used the EQ-i or EQ-i 2.0. It has the best norms, reliability, and validity of any self-report instrument and was the first one reviewed in the Buros Mental Measures Book. The EQ-i 2.0 is available in many different languages as it is used worldwide.
