This article summarises the process of creating a norm group
What is a Norm Group?
All tests on the Clevry assessment platform are 'norm-referenced'. This means that a candidate's score on a particular test is compared with a group of people who have taken that test before - this group is referred to as the norm group.
Comparisons to the norm group are used to convert ‘raw’ test scores (unaltered data) to normed scores in order to more accurately interpret results and give them meaning. Normed scores for the assessments are expressed in Stens, a type of standard scoring system.
Our Clevry online platform allows you to choose which norm group you would like to use for your particular test needs from a variety of available comparison groups.
Clevry's norm groups are reviewed regularly to ensure they are up to date, following best practice guidelines from the British Psychological Society and the European Federation of Psychologists' Associations. Norm groups updated within the last 10 years are considered to be of Excellent standard, and at Clevry we are proud to uphold such standards.
We offer the provision of bespoke norm groups from 200 candidate responses and will automatically calculate raw scores into Sten scores. For more information about any of our norm groups, please contact us at support.uk@clevry.com.
Choosing your Norm Group
Clevry allows you to choose which comparison group you would like to use for each of your assessments. We have general composite norm groups available for all assessments, along with some sector-specific norm groups.
You may want your campaigns to be in a particular language. The language you set your campaign in will determine the norm group your candidates are compared to. For example, if you choose to set your campaign in English, your candidates will be compared to a norm group from a particular globular region, and if you were to make a Spanish campaign, the norm group would be from a different global region. As a result, you would not be able to compare your candidates properly. Therefore, we recommend not making separate campaigns in different languages, but instead just making one campaign in one language, and then selecting the option for your candidates to choose what language they complete the assessments in within the campaign. This will mean that all your candidates are compared to the same norm group, rather than different norm groups if you were to make multiple campaigns in different languages.
