16 Personality Factors Questionnaire

The 16 Personality Factors (16PF®) questionnaire is a robust, reliable measure of 16 personality traits that describe and predict a person’s behaviour in a variety of contexts. The instrument is used to select, develop and motivate the people who make organisations thrive.

With over 50 years of research behind it, the insights provided by the 16PF® instrument are authenticated by over 2,700 independent, peer-reviewed research articles, making it a highly reliable, accurate predictor of future behaviour and likely success.

Interpreted by a qualified practitioner, the 16PF® instrument provides a breadth of insight that helps you to understand objectively who people are by getting a view of their whole personality, not just the behaviour they exhibit in professional contexts. It aims to reveal potential, confirm capacity to sustain performance in a larger role and helps identify development needs. This reduces the risk in decisions about key roles and promotions, at all levels, providing a perspective that is difficult to obtain from an interview alone.

The instrument can also act as a point of reference throughout a career, identifying development needs so that a person’s full potential can be realised.


Certification in the 16PF® Instrument

The 16PF® instrument is what we call ‘Restricted’ and you need to be trained and certified to access and use it. This ensures that the instrument is used for the purpose for which it was designed and that it is being administered and interpreted correctly.

We offer a  16PF® Certification Program that will qualify you in the professional and ethical administration of the 16PF® instrument and upon successful completion of the program, you will gain a certificate of qualification to purchase and use both the instrument and its reports.

If you would like to discuss a 2 day in-house Certification Program for your organisation, please contact us .
