The Trait Emotional Intelligence Questionnaire (TEIQue) is an integral part of the academic research program on trait emotional intelligence.  The latest version of the TEIQue is v. 1.50.  The TEIQue covers the sampling domain of trait EI comprehensively. 

The TEIQue is a scientific measurement instrument based exclusively on trait EI theory.  Trait EI theory is unrelated to what lay people understand by "emotional intelligence" or "EQ" and incompatible with other models of the construct.  The TEIQue is specifically developed and updated to provide a gateway to trait EI theory and it should not be seen as an alternative to the proliferating, and generally invalid, "EQ tests".
