A Personality Assessment for Employees Has to Pay off for the Employee

Pick the test by what the results are for. For hiring, use a Big Five or Hogan-style test validated for selection, read next to interviews. For a team workshop, DISC is quick and easy to talk about. For growth after the hire, pick a forced-choice test that hands the employee the full report.

A workplace personality test sums up how someone usually works: how they make decisions, how they talk to colleagues, how they handle pressure and deadlines, and the sort of work that keeps them going over months. It does not measure skill. A quiet sales rep can still close deals, and an outgoing engineer can still write careful code. Take what comes back as a sketch of habits, and check it against what the person does day to day.

What counts as an employee personality test

The US Equal Employment Opportunity Commission describes personality and integrity tests as tools that assess how far a person has certain traits, such as dependability or cooperativeness. At work the label covers three different uses. Some companies add a test to hiring, as one structured signal next to interviews. Some give it to current staff, for team workshops and better one-on-ones. Some build it into leadership programs, so new managers learn how they come across. The same test can show up in all three, but the stakes differ, and so do the rules.

Four families of workplace test, and what each one reports

Most workplace tests show a set of statements, add up the answers, and report a profile. What they report is where they part ways.

DISC splits behavior four ways: Dominance, Influence, Steadiness, and Conscientiousness. It is short, often around 15 minutes, and easy to talk about in a workshop because the four words stick. It describes communication style and not much beyond it.

The Myers-Briggs Type Indicator (MBTI) places each person in one of 16 four-letter types built from four preferences, like whether someone is introverted or extraverted. Teams like it because the types are memorable and the language is friendly.

The Big Five scores five broad traits on a scale: conscientiousness, extraversion, openness, agreeableness, and emotional stability. Most academic research on personality and work uses this model, and you can find free versions online.

Others include the Hogan inventories, which were designed with hiring in mind, the Enneagram, and CliftonStrengths, which lists a person's top talent themes. Our guide to business personality assessments compares six of these tool by tool.

Where Myers-Briggs still shows up at work, and where it stops being useful

Plenty of employers still run the MBTI at offsites and in leadership courses, and it works as an icebreaker. People learn that a quiet colleague may simply think before speaking. It stops helping when someone treats a type as a fixed fact about a person. Someone who sits close to the middle on introversion is handed the same letter as someone at the far end, so two people with the same type can work in very different ways. Little research ties a four-letter type to how well someone does a job, so leave it out of hiring calls. For a side-by-side look, read DISC vs Myers-Briggs.

Most tests in this category are self-report. You read a line like "I like to plan ahead" and score it from 1, not like me at all, to 5, exactly like me. That works well when the person has no reason to shade the answer, such as a curious employee doing it for their own interest. It works less well when a job, a promotion, or a manager's opinion is on the line.

Self-report versus forced-choice: why the format changes what you can trust

On a rating scale, nothing stops someone from marking themselves high on every trait an employer might want. Psychologists call this social desirability. It is less like lying and more like dressing up for an interview, and most people do it a little without noticing. The Big Five is usually given this way, which is one reason employers who use it in hiring read it next to interviews and work samples, never alone.

A forced-choice personality test for employees is built another way. Each item sets two statements of about equal appeal next to each other, such as "I finish what I start" and "I keep people in the loop," and asks which describes you better at work. Both are good traits to have. Marking one says something about what the person leans toward, and there is no way to claim both. Over many items, inflating everything is off the table, so the pattern that comes out tracks what the person does most often.

The format has costs. Forced-choice tests take more work to build, and the scoring is harder to explain to a skeptical team. Some people get annoyed when both statements fit them. That tension is the design doing its job, but warn people about it before they start, so nobody thinks the test is broken.

Pigment, the career intelligence assessment we make, uses this format. It asks 120 questions of this kind and scores traits on a sliding scale, covering how a person makes decisions, how they communicate, how they learn, and how they handle time. Every trait has two ends, and neither end is the better one.

How much a personality test predicts job performance

Some, but less than most vendors imply. The trait with the steadiest record is conscientiousness: being organized, dependable, and driven to finish. Murray Barrick and Michael Mount pooled 117 studies in 1991 and found it was the one Big Five trait that predicted performance in every job group they looked at, with a corrected correlation of about .22. The other four traits mattered only in some jobs, such as extraversion in sales and management.

How big is .22? A correlation runs from 0, no link, to 1, a perfect one. Frank Schmidt and John Hunter's 1998 review put conscientiousness at .31, behind general mental ability at .51 and structured interviews at .51. Paul Sackett and colleagues redid that math in 2022 with stricter corrections and brought most numbers down: structured interviews came out on top at .42, and conscientiousness fell to .19. So any personality assessment for employees is a modest signal. It adds something next to a good interview and is a poor stand-in for one.

Type tests have a further problem: stability. In David Pittenger's 1993 review of the research, between 39% and 76% of people were sorted into a different MBTI type when they took it a second time, some only five weeks later. A result that shifts that easily cannot carry a hiring call, though it can still start a good team conversation.

Whatever test you look at, ask the vendor two questions before you buy: does it give the same result when a person takes it twice, and does it predict anything you care about? The American Psychological Association's material on testing and assessment explains both ideas, reliability and validity, and what good evidence for each looks like.

Most teams that run a personality assessment for employees get a stack of profiles back, talk about them for an afternoon, and file them away, usually because nobody planned what to do with them next.

For the employee, a good result names how they work in words they can repeat to someone else: "I decide fast and fix things as I go," or "I need a day to think before I commit." That language helps in one-on-ones, in reviews, and when someone asks what kind of project they want next. Gallup's research on strengths at work finds that people whose jobs let them use their strengths do better work and stay more engaged, so the payoff is worth chasing.

For the manager, a result is an educated guess about what this person needs: more context or less, written updates or a quick call, room to run or a weekly check-in. Treat it as a starting point and ask the employee whether it rings true.

Turning a result into a real management decision

Pick one decision before anyone takes the test, and use the results to make it. Good examples are how to split work on a new project, how often to check in with each person, and who runs client calls while someone else owns the analysis.

Then follow three rules. Show each result to the person first, before anyone else sees it. Let them push back where it misses. And keep personality scores out of performance reviews, because a score describes a style, not how well someone did the job.

When two people clash, put their results side by side. A fast decider and a careful checker often see each other as reckless and slow. Seeing the pattern on paper takes the heat out of it, and they can agree on who does what. A poor match between a person's style and the team's habits can look like disengagement from the outside, which is the subject of our piece on how a bad type match can look like quiet quitting. And if you want to compare how people rate themselves with how colleagues rate them, our guide to the 360 personality assessment walks through how that kind of review runs.

Who reads the result changes how you should run the test.

For the employee taking it

Tell people why the company is running the test, who will see their results, and how long the data is kept. Make it optional for current staff where you can, and say so in writing. People answer more openly when they know a score will not follow them into a pay review.

Plan for access before launch day. Offer extra time, a version that works with screen readers, and a quiet place to take it. The Americans with Disabilities Act requires reasonable accommodations at work, and that covers how a test is given. Neurodivergent employees may answer questions about social settings or routines differently from their colleagues, and their results can read as odd when they are simply accurate. Go through results together with each of them.

Manager personality assessment: what changes at the leadership level

For managers the questions shift. How do they make calls under pressure? How do they give hard feedback? Do they hold on too tight, or step back too far? A manager's habits spread to everyone who reports to them, so a blind spot costs more here than anywhere else on the team.

Use a manager personality assessment inside coaching, where the aim is growth. Pair it with feedback from the people they lead, since the gap between how a manager sees themselves and how their team sees them is often the most useful finding. Pigment's report has a section on working with different styles, including how to handle conflict, which gives a new manager something concrete to practice.

For a whole team

Run it together, then let each person choose what to share. Map the styles on one page and look for gaps. A team full of fast deciders with nobody checking details will ship quickly and miss things. Pigment groups people by four working styles, and a team can see at a glance whether most people fall into the Accelerator pattern, fast and results-driven, or the Analyst pattern, careful and data-led. Neither is better. The point is knowing who covers what.

Decide what the results are for first. Choosing the personality assessment for employees comes second. Three questions sort most cases: is this for hiring or for people you already employ, who will see the results, and what will you change once you have them?

What US hiring law allows

In the US, employers can generally use these tests, with conditions. What follows is a short summary for orientation; take legal questions to a lawyer. The EEOC's page on employment tests and selection procedures explains that Title VII bars neutral tests that disproportionately exclude people based on race, color, religion, sex, or national origin, unless the test is job-related and consistent with business necessity. The same page says employers must make reasonable accommodations in how tests are given, and may not require medical examinations until after a conditional job offer.

That last rule matters for personality tests. The EEOC's ADA guidance on medical examinations says psychological tests designed to identify a mental disorder count as medical exams, while tests that measure traits such as honesty, preferences, and habits do not. So a clinical instrument has no place in pre-offer hiring. State laws and other countries add their own rules, so check with employment counsel before a test touches a hiring decision.

Start from the decision the results will feed

Hiring: use an instrument designed and validated for selection, give it to every candidate for the role in the same way, and count it as one piece of evidence beside structured interviews and work samples. Never let one score decide.

Team workshops: DISC or the MBTI are fine. They are cheap, quick, and give people easy words for their differences.

Development and project matching: pick a forced-choice test that gives the employee the full report, so the result turns into conversations that keep going. This is where Pigment fits.

Where an interview personality assessment fits in your hiring process

Run it after the basic screen and before final interviews. Use the results to write sharper interview questions. If a candidate scores low on attention to detail, ask about the last time they caught an error before it went out. Tell candidates up front that a test is part of the process and how it will be used. The candidate's side of the same process is in our piece on what candidates face in a hiring personality test, and the DISC test for employers guide shows what a candidate sees in one common format.

Pigment does not belong in this step. It was built for the person taking it, and it has not finished a formal validation study of its own, so it should never be used to choose between candidates. Its place is after the hire: helping people and their managers understand how they work best.
