Norm update and FAQs


Q: What is a norm? How is it used?

A norm is a set of data collected from people who have completed the Hogan assessments. We use these norms to convert a person’s raw scores into more meaningful percentile scores, which tell us how that person’s scores compare to the scores of other people in the norm.

For example, if a person has a percentile score of 45, that person scored the same as or higher than 45% of the norm group.

With the move to a four-point response scale, a new data set was required in order to provide the appropriate corresponding percentile scores. We started collecting these norm data in 2018 and finalized this new global norm in late 2022.

Q: How did the scoring change for the HPI and HDS and what makes this scoring approach better?

The HPI and HDS both originally used a two-point True/False response scale. In September 2018 Hogan started collecting responses on the HPI and HDS using a four-point response scale (Strongly Agree, Agree, Disagree, and Strongly Disagree). The upgrade to a four-point response scale increases the range of possible responses, which allows participants to choose answers that better reflect how they feel about each HPI and HDS item. This approach allows for more precise scoring of the main scales and subscales, which further enhances the already considerable interpretive power of the assessments.

Q: What are the benefits of using the upgraded scoring and norm?

By moving from a two-point to a four-point response scale, we are increasing the precision with which we can measure and generate main scale and subscale scores. Think of this as adding more degrees on a thermometer, more marks on a ruler, or more notches on a belt.

Primarily, we expect this increased precision will result in an improved feedback experience for participants. Because we can now make finer distinctions in how people score, participants should find their results to be even more “on target,” particularly at the subscale level.

Additionally, there are multiple benefits in using the related upgraded norm. Because this norm is based on the latest data gathered by Hogan, it provides better representation of work-relevant demographic groups, including age, gender, job, industry, and assessment language. Some notable changes are:

Gender representation improved

  • Previous Norm: 42% women/58% men
  • New Norm: 46% women/54% men

Number of countries/territories increased by 11

  • Previous Norm: 179
  • New Norm: 190

Number of languages and dialects up to 48 total, with Lithuanian, Montenegrin, and Slovene being new additions

Q: Should I change how I interpret the results?

No. You can interpret main scale percentile scores and subscale “brick” counts in the exact same way you currently do. We are changing nothing about the underlying dimensions or constructs that our assessments measure or predict.

Q: When will the new scoring and norms become available?

Starting June 6, 2023, the new norms will be in place for all clients.

Q: How do I start using the new scoring and norms?

The move to the new scoring and norms will be automatic, so it’s likely you won’t have to do anything!

Q: Is there an additional cost for using the new scoring and norms?
