Areas of application

The WPI can be applied to all issues whereby insight into personality is important. Many professionals use the WPI for all kinds of assessments, coaching and career advice situations.


The WPI has been developed on the basis of the needs of assessment psychologists and the Big Five personality theory. That has resulted in a number of important improvements in the HR working area.

Conscientiousness is known to be an important factor for assessing someone’s way of working and performance. The WPI makes a distinction between two Conscientiousness factors, namely Exuberance and Structure. This enables you to distinguish between the precise side and the conscience-driven side of Conscientiousness. That is important, because these scales are a good indicator of successful performance. But it enables you to place a different focus according to the job position. For example, many account managers are driven but not always precise. For them, it is all about the bigger picture. For other job positions, it is exactly the structure side and eye for detail that is much more important, such as for Controllers.

In addition, there are a number of differences with traditional Big Five questionnaires that make the WPI eminently suitable for an assessment programme. For example, Influence forms a separate factor, with scales such as Dominance, Status, Competition and Self-assurance.

You have access to three WPI variants:

WPI Normative
In the normative version, the candidate indicates the degree to which he recognises himself in a statement. This questionnaire has two norm groups, one for advice situations and one for selection situations.

WPI Normative Example

WPI Ipsative
We constructed an ipsative WPI version at the request of our clients. In this version, candidates have to choose between two possible answers. This questionnaire is less susceptible to ‘faking good’ and socially desirable responses. Some advisors prefer to use this ipsative version in selection procedures for this reason.

WPI Compact
All questions have been translated to the B1 language level for the WPI Compact. This version also achieved good results with candidates with an A2 language level. It means this questionnaire can be applied to candidates with lower language proficiency levels or lower educational levels.
