We are committed to continuous improvement

Join our upcoming people development summits...National Education Show, Cardiff: 13 October...

To ensure that we continue to provide you with the most effective, reliable and valid suite of assessments, I am pleased to announce that we have updated our norm groups for both the General Intelligence Assessment (GIA) and Trait Emotional Intelligence Questionnaire (TEIQue), which will go live to all UK clients on the 24th April 2017.

What are norms?

Norms provide a frame of reference for interpreting assessment scores. To create norms, data is collected from a representative sample of the working population. The norm group is then used to compare an individual’s scores against the scores of their peers. This tells you how an individual has performed compared to the working population. It is best practice to update assessment norms every few years to ensure scores are being compared to a representative sample of the current population.

When are our norms changing?

All GIA and TEIQue reports generated after 24th April 2017 will default to the new norms. If you would prefer to use the old norms, you can continue to do so by selecting the old norm when creating a report on the Thomas Hub. However, we strongly recommend that you do transition to using the most current norms as soon as possible and you will be able to recreate existing TEIQue and GIA reports based on these new norms.

Please note: people should only be compared to each other when their reports have been generated based on the same norm group.

Please find below further details on the specific changes to each of the assessment norms.

If you have any questions regarding the new norms, please get in touch with our in-house psychology department by emailing [email protected] who will be more than happy to assist with your enquiry.

Information on the 2017 Norms

General Intelligence Assessment

The new norm group is larger and more representative than the 2011 norm group. More demographic data was captured from the sample to ensure it is in line with the current working population. The new norm reflects changes in the working population over the past few years. Statistically, the new norms are also more robust.

The weighting of the five GIA tests has been amended slightly to reflect the overall performance trends in the new norm population. This means that individuals now have to score slightly differently on some of the tests in order to be given the same percentile ranking with the 2011 norms. It’s important to note that these changes are subtle: the differences are never more than the equivalent of one correct answer on a subtest.

Perceptual Speed

You will have to score the same or slightly higher to receive the same percentile rank as in 2011.

Number Speed & Accuracy

You will have to score the same or slightly higher to receive the same percentile rank as in 2011.

Spatial Visualisation

You will have to score the same or slightly higher to receive the same percentile rank as in 2011.

Word Meaning

You will have to score the same or slightly lower to receive the same percentile rank as in 2011.

Trait Emotional Intelligence Questionnaire

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.
