Thomas International’s Personal Profile Analysis (PPA), otherwise known as the DISC test, is the leading online assessment tool for employers or HR professionals. The PPA is a written and clear report on the work behaviour and personality of an applicant or employee. It is a powerful tool for evaluating someone’s behaviour in the work situation in a fast, reliable and objective manner, and for mapping out a person’s key traits.

An online PPA assessment provides a clear overview of:

  • Key traits
  • Character traits and behaviour on the shop floor
  • Motivation
  • Communication and social skills
  • The position for which the candidate is best suited
The PPA assessment takes around 10 minutes to complete.

The PPA report

On the development of the PPA online assessment The Personal Profile Analysis is an assessment based on Dr. W.M. Marston’s DISC theory from 1928. The method was developed by Thomas Hendrickson at the beginning of the nineteen-sixties and its full name is Thomas International’s Personal Profile Analysis method.

HThe DISC model is a psychometric test and maps out strengths, weaknesses, communication and preferred behaviour, among other things.

The written result of the PPA assessment is supported in three diagrams that provide plenty of useful information down to the smallest detail. The three diagrams show how someone sees themselves, how that person responds and acts in stressful situations and finally how he or she faces the outside world.
