Personality tests, while imperfect, can often act as helpful shortcuts for understanding people on your team — and when used as part of a structured approach, they can do more than that.
Taking the right approach can help teams click better, managers make smarter decisions, and remove some of the guesswork from the hiring process. But they’re not magic wands. Implementation and execution are everything when identifying key personality traits.
A workplace personality assessment gives you a structured, data-backed way to understand how your people are wired to work — how they communicate, make decisions, and respond to pressure. Used well, they inform hiring, strengthen team dynamics, and help managers lead more effectively. Below, we’ll cover:
- The basics of popular personality tests and what they’re designed to do
- How and when to use them effectively in your workplace
- Best practices (and a few pitfalls to avoid) when rolling out assessments
- How tools like The Predictive Index go beyond traditional personality tests to drive results
What is a workplace personality assessment?
A workplace personality assessment is a validated tool that measures behavioral tendencies, communication styles, and work preferences. It’s built for professional contexts, not general self-discovery. In the workplace, these assessments can help teams improve how they interact with each other, strengthen relationships, and support overall leadership development.
Options like the Myers-Briggs Type Indicator (MBTI) questionnaire, the Big Five, the PI Behavioral Assessment, and DiSC are some of the most recognized tools for understanding workplace dynamics. They provide insights into how different working styles contribute to team performance and productivity, making them a practical resource for team building.
The term is sometimes used interchangeably with “behavioral assessment” or “personality test for work.” The distinction matters. The most useful workplace tools go beyond personality labels to measure how a person is wired to operate in a role, not just who they are.

When personality tests are used in the workplace
From improving team dynamics to shaping leadership strategies, here are some practical ways that identifying personality types can be helpful in the workplace:
- Connect remote teams: For remote or hybrid teams, personality tests help improve collaboration and team building within an organization by offering insights into individual communication styles and working preferences, such as an individual’s conscientiousness.
- Support hiring decisions: These tests can provide additional context about a candidate’s potential fit with the company culture. However, it’s important to not rely too heavily on the results, as diversity in thinking styles, as well as different experiences, can often drive innovation.
- Improve team development: Personality assessments help managers strengthen team performance by revealing individual strengths and areas for growth.
- Boost employee self-awareness: By understanding their own personality traits, employees can better navigate workplace relationships and contribute more effectively to the team.
- Identify potential leaders: Personality assessments can reveal traits associated with leadership, such as decisiveness, emotional intelligence, and adaptability, helping organizations identify and nurture future leaders.
While personality tests can provide valuable insights, it’s worth noting that they’re just one piece of a larger strategy.
Types of personality assessments
Not every workplace personality assessment is built for the same purpose. Some are designed for self-discovery. Others are built for team workshops. A smaller number are validated for high-stakes decisions, such as hiring. The difference matters because using the wrong tool produces data you can’t act on, or data that creates legal exposure.
What separates a useful workplace assessment from a generic one is the science behind it: whether it’s been validated against real job performance outcomes, whether it measures work-relevant behaviors, and whether the results translate into decisions a manager can actually make.
Here are the most common types:
Big Five (OCEAN)
The Big Five measures five traits: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. It’s well-established in academic research, though results can feel abstract in a workplace context. Without a structured debrief, the data is hard to translate into day-to-day decisions.
Myers-Briggs (MBTI)
MBTI organizes people into 16 types based on four preference pairs. It works well for self-awareness conversations and team workshops. A significant portion of people get a different result when retested, which is why it’s generally not recommended for hiring or performance decisions.
DISC
DISC profiles people across four behavioral styles: Dominance, Influence, Steadiness, and Conscientiousness. It’s practical for team communication and manager-employee conversations. The DISC framework itself acknowledges that it is not validated for hiring use.
PI Behavioral Assessment
The PI Behavioral Assessment measures four core drives: Dominance, Extraversion, Patience, and Formality. It’s built specifically for the workplace and independently audited by EFPA for validity and reliability. Where most personality tools produce a profile, PI produces job target match scores that let you compare candidates directly against the requirements of a role, making it one of the few assessments designed to support both hiring decisions and post-hire development.
The pros and cons of using personality assessments in hiring
Personality assessments can sharpen hiring decisions when used correctly. Like any tool, they have real strengths and real limitations worth understanding before you roll them out.
| Pros | Cons |
| Objective data reduces gut-driven decisions. Structured assessment results give hiring managers a consistent basis for comparing candidates, which reduces the influence of unconscious bias and first-impression effects. | Results can be misread without proper training. Without guidance on how to interpret profiles, managers may draw conclusions that the data doesn’t support. Training and a clear debrief process matter as much as the tool itself. |
| Validated assessments predict job performance. When built on rigorous psychological research, behavioral assessments can predict how a candidate will perform in a specific role, not just whether they seem like a good fit. | Some tools carry cultural bias. Poorly designed assessments may not account for cultural differences in how people respond to questions, which can disadvantage certain candidate groups and create adverse impact risk. |
| Assessments improve hiring efficiency at scale. Job target match scores allow teams to prioritize candidates more systematically across large applicant pools, reducing time spent on poor-fit interviews. | Assessment data should inform decisions, not make them. Over-relying on results means overlooking experience, skills, and context that a behavioral profile cannot capture. Personality data works best as one input among several. |
| Behavioral and cognitive data together outperform either alone. Research shows that combining personality measures with cognitive ability assessments produces more accurate predictions of job performance than either measure used independently. |
Step-by-step guide on how to use personality tests in the workplace
Not every organization will apply personality testing in the same manner. The employee makeup and the company’s mission, among other factors, matter in terms of rollout. For optimal effectiveness, companies should:
Understand the organization’s goals and objectives.
Before introducing personality tests, identify what you aim to achieve. Are you looking to boost team collaboration, make more informed hiring decisions, or improve leadership development? Defining clear goals ensures the assessment aligns with your organizational priorities.
Choose the right personality assessment.
Not all personality tests are created equal. Select one that aligns with your outlined objectives. For instance, tools from The Predictive Index can offer actionable insights tailored to workforce optimization and leadership challenges.
Communicate the process to the team.
Once you’ve selected a personality assessment, involve everyone in the organization so they’re aware of the process. Transparency is key. Explain the purpose, the expected outcomes, and how it benefits both the team and the individual employees.
Facilitate the assessment.
Make it easy for employees to complete the test. For online assessments, provide clear instructions and set a deadline. If it’s a group assessment, schedule a convenient time to ensure participation. The goal is to create an accessible and stress-free experience that doesn’t interfere with everyone’s day-to-day.
Review the data as a team.
Once assessments are completed, dive into the results. Look for patterns that highlight strengths (like agreeableness, the mix of extroversion and introversion, and competencies) areas for growth, or opportunities for better team alignment. Share the findings with the team and collaboratively set an action plan with next steps. An organization can hold itself accountable for executing this action plan through the use of frameworks such as SMART goals.
Leverage the data for long-term impact.
Use the test results gained to shape your hiring strategy, improve team dynamics, or design tailored employee development programs. HR teams can also harness this data to refine recruitment processes and strengthen employee engagement initiatives.

Best practices for personality tests in the workplace
Personality testing can be a boon to your workplace and workforce when applied properly. That means using them in conjunction with other tools and alongside other data, and applying it in context.
Avoid making assumptions based on results.
Personality assessments typically highlight an individual’s dominant traits, but they don’t define the entirety of a person’s abilities or potential.
Choose dynamic, actionable assessments.
Select assessments that provide clear and meaningful feedback for employees. Avoid static tools that fail to offer actionable next steps or insights for team development and individual growth.
Ensure inclusivity across the organization.
Personality tests should involve everyone within the organization to promote team alignment and inclusivity. Excluding individuals or teams can lead to incomplete results and undermine the value of the data collected.
Understand the purpose of the assessment.
Each personality test has its own logic and set of results. Before implementing one, ensure it aligns with your organizational goals.
Communicate the importance of the assessment to employees.
Employees should know why they’re taking the test and how the results will be used. Transparency fosters trust and engagement, making team members more likely to embrace the process and its outcomes.
How to interpret workplace personality assessment results
Assessment results are only useful if the people receiving them know what to do with them.
Most workplace assessments produce a profile that describes behavioral tendencies across a set of dimensions. With PI, those dimensions are Dominance, Extraversion, Patience, and Formality. A high score in any dimension isn’t good or bad in isolation. It describes a natural working style, not a ranking.
Where interpretation gets practical is in the match between a person’s profile and the requirements of a role. A job target score tells you how closely someone’s behavioral drives align with what the role actually demands. A strong match suggests the work will feel natural to that person. A weaker match doesn’t disqualify a candidate. It flags where they may need more support, where friction is likely, and what to probe in an interview.
How to use personality assessments for employee development
The same data that informs a hiring decision has value long after someone is onboarded. Behavioral profiles give managers a practical lens for understanding how to get the best from each person on their team.
In practice, that looks like adjusting how feedback is delivered, structuring 1:1s around what actually motivates each employee, and identifying development opportunities that align with how someone is wired. An employee who scores high in Formality may want clear structure and detailed briefs. One who scores high in Dominance may want autonomy and a faster pace of growth.
PI’s Inspire module is built specifically for this use case, turning behavioral data into a continuous coaching tool rather than a one-time assessment result.
Key takeaways
- Not all workplace personality assessments are built for the same purpose. Consumer-grade tools like MBTI work for self-awareness. Validated, workplace-specific tools like the PI Behavioral Assessment are built for hiring and development decisions.
- The most useful assessments produce actionable data, not just personality labels. Look for tools with documented validity studies and independent audits.
- Implementation matters as much as the tool. Communicating purpose, facilitating a proper debrief, and applying results consistently determine whether assessment data actually changes how your team operates.
- Personality data works best as one input among several. It adds meaningful context to hiring and development decisions, but should never be the sole basis for either.
- Behavioral profiles have long-term value. The same data that informs a hiring decision can shape how a manager coaches, gives feedback, and develops an employee well beyond onboarding.
