Last Updated: May 24th, 2026 | 10-minute read
The Predictive Index 17 reference profiles, also referred to as personality types, describe common workplace personalities based on the theory behind the Predictive Index Behavioral Assessment. A reference profile is created for each candidate, highlighting their strengths and weaknesses.
On this page, you will find a complete review of all 17 Predictive Index personality types, an explanation of the four reference profile categories, and a detailed look at the four PI personality factors and how they fit into each profile.
By identifying your closest PI Index reference profile, you'll gain an advantage in approaching the Predictive Index Behavioral Assessment. For free sample questions, see the Free Predictive Index Behavioral Assessment and Cognitive Assessment pages.

What do your PI results really mean?
In this short video, you'll find a full breakdown of the core concepts of the Predictive Index, the four key factors, and how your unique combination of behavioral drives translates into one of the 17 reference profiles. Gain an inside perspective on what employers are truly looking for.
The Predictive Index is a science-backed tool that helps forecast job performance. Developed by Arnold Daniels in the 1950s, the PI Behavioral Assessment (PIBA) has been used for nearly 70 years by thousands of companies worldwide to identify and select the best candidates.
The Predictive Index 17 reference profiles are created based on the results of the PIBA, a unique personality test in which you must select personality characteristics/adjectives from a list of 86 that describe how you see yourself and how you believe you are supposed to behave at work.
Based on your choices, a profile is created from four underlying factors, which are essentially groups of personality characteristics. Each of the PI personality types has a different balance of these four factors, reflecting unique workplace characters with distinct work styles, social preferences, and preferred environments.
By learning about the Predictive Index reference profiles and the theory behind them, you will be able to understand what your assessor is looking for and arrive well-prepared for your assessment.
The four PI personality factors are broad categories that each of the 86 personality traits belong to. After completing the test, your answers give weight to each of these factors. By calculating how high or low each factor is, your unique Predictive Index profile is created.
The idea that certain fundamental traits exist within a limited number of domains, and that different combinations of these traits form distinct "personality profiles," is the basis of many personality theories. Examples of questionnaires that use the "Trait Theories" approach include the Big Five model, the SHL Occupational Personality Questionnaire, the 16 Personalities Test, and the MMPI.
Within the 17 Predictive Index profiles, there is a further division into four overarching categories. These group together the types that have similar scores in the four predictive index factors, making it easier to grasp broader behavioral tendencies:
Predictive Index reference profiles belonging to this group are generally more task-oriented than people-oriented. They tend to work at a faster pace and are typically more dominant and formal than socially extroverted.
Predictive Index reference profiles belonging to this category are highly relationship-focused and highly extroverted in comparison to others. They thrive on interaction and influence.
Predictive Index profiles belonging to this category are low in dominance and extraversion, and high in formality. People belonging to PI stabilizing profiles work well in highly structured and formal environments, preferring consistency.
Predictive Index profiles belonging to this category are high in the dominance and patience factors and low in extraversion. People belonging to these profiles are very detail-oriented and prefer having high levels of control over their work.
There isn't a single "good" Predictive Index (PI) score, as it's designed to assess behavioral and cognitive strengths rather than being a pass/fail test. The focus is on aligning candidate profiles with job requirements, with employers setting their own target scores. Here’s a simplified breakdown of interpreting PI scores:

The Predictive Index is a globally recognized tool. Here are some of the companies that leverage PI in their hiring and talent optimization:
There are 17 Predictive Index (PI) reference profiles, often referred to as personality types, derived from the Predictive Index Behavioral Assessment. These profiles describe common workplace behavioral patterns.
No single PI profile is universally "best" for leadership, as effective leadership depends on the specific context, team, and organizational culture.
However, profiles with higher Dominance and Extraversion often show natural leadership drives. The "Captain" and "Persuader" profiles, for example, frequently demonstrate strong leadership characteristics due to their drive and influence.
What we've observed in thousands of successful candidates is that the best leaders often understand their own profile and how to adapt it to their team's needs.
The Predictive Index reveals your natural behavioral drives and needs across four key factors: Dominance, Extraversion, Patience, and Formality.
It helps you understand your innate work style, how you prefer to interact with others, your pace of work, and your approach to rules and structure. This self-awareness can be invaluable for career development and finding roles that align with your natural strengths.
There isn't a "good" or "bad" PI score in terms of pass/fail. The Predictive Index is designed for match-making. A "good" score means your behavioral profile (your combination of the four factors) aligns well with the specific behavioral demands of the job you're applying for, as determined by the employer's job target. It's about fit, not a high score.
The "Scholar" is one of the 17 Predictive Index reference profiles, typically categorized under the Persistent Profiles.
A Scholar is often described as analytical, precise, detail-oriented, and driven by a deep understanding of subjects. They excel in roles requiring thorough research, meticulous attention, and independent, focused work, prioritizing accuracy and intellectual mastery.
The four core behavioral factors (or areas) measured by the Predictive Index Behavioral Assessment are: Dominance, Extraversion, Patience, and Formality.
These represent fundamental drives that shape an individual's workplace behavior.
While Predictive Index doesn't publicly state a "rarest" profile, some combinations of the four factors are statistically less common than others.
Generally, profiles with extreme or highly contrasting scores across all four factors might appear less frequently in the general population compared to more balanced profiles.
To prepare for the Predictive Index test, it's crucial to understand the purpose and mechanics of both the Behavioral Assessment (PIBA) and the Cognitive Assessment (PICA).
For the PIBA, familiarize yourself with the 17 reference profiles and the four core factors. For the PICA, practice various verbal, numerical, and abstract reasoning questions under timed conditions. Using accurate practice tests that mimic the real exam format is highly recommended.
