Personality Profile Analysis

Page Overview:

At Aaron Wallis Sales Recruitment, we enhance hiring precision through our integration of the Personality Profile Analysis (PPA) from Thomas International, part of our standard psychometric profiling suite. This quick, robust tool uses the trusted DISC model to assess candidate traits in just a few minutes, revealing how they behave at work, how others perceive them, and how they respond under pressure. By comparing each candidate's PPA with your role's Human Job Analysis (HJA), we help you move beyond CVs to truly match behavioural fit, cultural alignment, and performance potential with confidence.

Aaron Wallis offers the PPA, or Personality Profile Analysis, as a quick psychometric tool that is excellent as an aide for an interview and is published by Thomas International. The PPA was one of the first psychometrics that was commercially available and commonly referred to as DISC or simply Thomas!

The tool is considered both quick and effective for pre-selection and as an interview guide for selection, with its origins in the United States. The psychometric tool is commonly used in conjunction with the HJA (Human Job Analysis) to benchmark selected candidates against the traits required by the role (the HJA is completed by the employer, and the PPA by each candidate - the resulting reports are then compared and contrasted together.

PPA is a useful psychometric questionnaire for use in both sales and non-sales roles, and whilst it was initially published in its current form in 1998, it was revised and updated in 2003. Completed by candidates in less than ten minutes, the PPA is available both online and as a paper-and-pencil questionnaire. Each candidate is given 24 sections to complete, each of which contains four adjectives. They are then asked to score one adjective 'M', which is the word that is most like them, and one adjective 'L', which is the word that is least like them.

The report that is generated uses the DISC psychometric structure, which has its origins in Marston's theory.

The Disc profile report indicates and gives feedback upon the following four personality traits:

- Dominance - Descriptive words could be decisiveness, persistence, dogmatism, determination, self-assuredness, assertiveness, drive, and forcefulness.
- Influence - With descriptive words such as Interpersonal skills, social sophistication, interactivity, gregariousness, persuasive ability, sociability, friendliness, affability, and intuitiveness.
- Steadiness(pace) - Descriptive words are, for instance, restlessness, innovation, energy, reliability, ability to perform repetitive tasks, steadfastness, and dependability.
- Compliance with descriptive words such as meticulousness, ability to comply, attitude towards following structure and process, rules orientation, conforming, individualistic,

PPA has been translated into over 46 languages, allowing it to be undertaken in the candidate's mother tongue. This has proven to be a fairer and more validated way to benchmark candidates from different nations.

The resulting report presents three graphs illustrating the above four characteristics, which consider the candidate's responses and score them on a range from -21 to +21. The three graphs describe:

- How the candidate perceives themselves at work
- How the candidate perceives others to perceive them at work
- How the candidate perceives themselves to react under pressure

Thereafter, a wide range of graphical and narrative reports can be generated from this 'raw' data, depending on the purpose of the analysis. These reports can be tailored for:

- Sales
- Management
- Sales Interview Questionnaire
- Management Questionnaire
- Training Needs
- Comparison against HJA (Human Job Analysis)
- And even an indication of Driving style!

There are many other guides available, but these are the guides used and recommended by Aaron Wallis, particularly for sales recruitment and management recruitment.

Many of these offer comprehensive interview questions and act as very useful interview guides.
