When a candidate completes a TEIQue, their raw scores are converted into percentiles based on where they sit within the norm group. For example, a candidate obtaining the 50th percentile on a particular facet had a score higher than or equal to 50% of the norm group. The norm group allows us to infer that this person would score higher than or equal to 50% of the population.
The 2017 sample is more representative of the current working population. The 2017 norm group is much larger than the 2010 norm group and has captured more demographic data to ensure the group is reflective of the current working population in the United Kingdom
Generally, individuals will find that their trait scores will be ranked slightly lower when compared to the more robust 2017 norm group. This does not mean an individual has lower trait emotional intelligence that before, it just reflects where their scores are ranked compared to a larger reference sample.
It is important to reiterate that high percentiles are not necessarily desirable and low percentiles are not necessarily undesirable. There are positive and negative manifestations of both high and low scores.
The Trait Emotional Intelligence Questionnaire (TEIQue) was developed, and is continually updated, by K. V. Petrides, PhD at his London Psychometric Laboratory, currently based at UCL. It is one of the world's best-researched and most widely applied psychometric instruments. For more information about the scientific pedigree of the TEIQue, go to www.psychometriclab.com.
