The Big Five personality test: how to take one and read it

A Big Five personality test asks you to rate a few dozen statements about yourself and returns a score on five broad dimensions: Openness to Experience, Conscientiousness, Extraversion, Agreeableness and Neuroticism. Good tests ask several questions per trait and report each one as a percentile against a reference sample. The result describes where you sit relative to other people, not which category you belong to.

What is a Big Five personality test?

A Big Five personality test is a questionnaire that measures five broad dimensions of personality and reports where you fall on each one. The five were not invented and then illustrated. They came out of decades of work on the words people use to describe each other, and the structure held through repeated attempts to replace it (Goldberg, 1993). The same five factors turn up in questionnaire scales and in ratings made by people who know the person being rated, which is a stronger result than self-description alone (McCrae & Costa, 1987). For the model itself, the letters and what each dimension covers, read the OCEAN personality test first. This page is the practical half: which tests exist, how to answer one properly, and what to do with the numbers.

Which Big Five tests can you actually take?

Almost everything you will meet online is one of a small number of instruments, or a site's own implementation of one. They differ mainly in length, and length buys resolution rather than accuracy at the broad level.

Big Five formats, from shortest to longest
TestQuestionsRough timeWhat you get
BFI-260About 10 minutesFive domains and 15 facets, the facets adding prediction beyond the domains (Soto & John, 2017). Free for research and educational use
IPIP-NEO-120120About 15 minutesFive domains and all 30 facets, four items each, with acceptable reliability and a structure closely matching the NEO PI-R (Johnson, 2014)
IPIP-NEO-300300About 40 minutesThe same 30 facets with more items each, from a public-domain pool anyone may use (Goldberg et al., 2006)
TIPI10Under two minutesFive domain scores only. Its authors call it inferior to standard measures and advise it where the alternative is measuring nothing (Gosling et al., 2003)
NEO inventories60 in the short form, several times that in the full one10 to 45 minutesFive domains, and six facets beneath each in the full form; commercial (Costa & McCrae, 1992)
Wellington Snapshot60About 7 minutesA percentile, a band and a written page for each of 6 dimensions, including Honesty-Humility

The times are estimates from the item counts at an unhurried pace, not published figures. The pattern underneath them is what matters. Ten questions place you on five dimensions roughly, sixty do it comfortably, and a hundred and twenty reach thirty narrower traits. Extra length past the first few dozen items buys breadth rather than better domain scores. Some tests also report a sixth dimension, Honesty-Humility, covering sincerity, fairness and modesty, which the five-factor solution does not carry on its own. If you are choosing between the free options, free Big Five tests, compared sets them side by side, and what free usually means covers the arrangements behind them.

How do you take a Big Five test well?

The questions look easy, which is exactly why people answer them badly. A Big Five test is a self-report measure, so what it returns depends on the self you had in mind while answering. Six habits make the result worth reading.

  • Answer as you typically are, not as you are today. The traits are dispositions that show up across months, not moods. If you have had a bad week, rate the person you have been over the last year or two.
  • Do not answer as a job interview. Presenting a polished version produces a polished profile, which tells you nothing you did not already decide. Nobody is scoring this, and there is no good result to aim at.
  • Take the first reading, not the fifth. Reading a statement four times turns a quick judgement into an argument with yourself. The first honest reaction is usually the more accurate one.
  • Use the middle when the middle is true. A neutral answer is information. Avoiding it because it feels indecisive pushes scores outward and makes the profile look more extreme than you are.
  • Answer about behaviour, not intention. The question is how you usually act, not how you would like to act or how you act on a good day.

There is a limit no amount of care will get past. A questionnaire about yourself measures what you notice and are willing to report. People who know you can see things you cannot, which is why the five factors show substantial but far from perfect agreement between self-reports and peer ratings (McCrae & Costa, 1987). Treat the result as one good view rather than the whole picture.

How do you read a Big Five result?

Most tests return a percentile for each dimension, sometimes with a band label and a paragraph of description. A percentile of 68 on Conscientiousness means roughly 68 percent of the reference sample scored lower than you. It is a position in a crowd, not a mark out of a hundred.

  • Read the distance from the middle. A score of 52 and a score of 48 are the same finding, and middling scores are the commonest result on most traits. Being typical on a dimension is real information about you.
  • Mind the boundary. Wide bands exist because measurement is imprecise. A score sitting just inside one band can sit just outside it at a retake without anything having changed, so read the percentile and treat the band as a label for it.
  • Check which way the fifth scale runs. Neuroticism and Emotional Stability are one dimension reported in opposite directions. Two tests can agree about you perfectly and appear to contradict each other.
  • Go down a level when the description is half right. Domains are averages, and averages hide their parts. Facet scores tell you which half of a domain description belongs to you, and facets add predictive power that the five domain scores alone do not carry (Soto & John, 2017).
  • Ask which sample you are being compared with. A percentile is meaningless without a reference group. An honest report names the sample and says plainly when its norms are still provisional.

If the numbers feel slippery, how to read your personality test scores works through a full result line by line, and the Big Five facets explains the level beneath the five. Between the two levels there is a third: each domain also splits into two broader aspects, ten in all (DeYoung et al., 2007), set out in the ten Big Five aspects.

What can a Big Five test tell you, and what can it not?

It is worth being precise about this, because the gap between what the measure supports and what people do with it is where most of the disappointment lives.

  • It can place you relative to other people on five or six broad dispositions, with reasonable reliability if it asks enough questions per trait.
  • It can point you at the narrower trait doing the work, if it reports facets. That is the level where a description becomes something you could act on (Soto & John, 2017).
  • It cannot sort you into a kind of person. There are no categories in the data, and rounding a continuous score to one side of a line discards the degree, which is the part carrying the information.
  • It cannot decide anything about your worth, your ability or your future. Traits are dispositions, not capacities, and no profile is better than another.
  • It cannot be trusted when it is very short. Brief scales understate how much traits actually matter and make rival explanations look more important than they are, and the printed result gives no sign of it (Credé et al., 2012).

The reasonable use is as a structured second opinion about yourself: a vocabulary, a rough position on each dimension, and hypotheses to check against your own week. That is genuinely useful, and it is less than a verdict.

How does Wellington's Snapshot work?

Wellington is a science-based personality assessment from Therabot Labs LLC. It measures personality as continuous traits, built on the Big Five and HEXACO models, and writes the results back as a personal report rather than a type.

The free Snapshot is 60 questions and about 7 minutes, ten statements for each of 6 dimensions: Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openness to Experience and Honesty-Humility. The first ten questions are answered before anything is asked of you. After question ten you sign in with an email address, so your answers are saved, a half-finished sitting can be picked up on another device, and your results have somewhere to be shown. There is no card at any point in the free tier.

Each statement is rated from "Very inaccurate" to "Very accurate". Reverse-keyed items are flipped, each dimension is the average of its statements, and that average is reported as a percentile against the reference sample, in one of three bands: Quiet below the 30th percentile, Balanced to the 70th, High above. The bands and the Portrait names exist to make the result easier to talk about; the percentile is the measurement, and it is always shown alongside. Our norms are provisional while the norming sample is completed, and the report says so rather than leaving you to assume otherwise. In the written report, every trait has three pages, one per band, written in advance by our writing and psychology team, and your answers choose which one you read. Wellington is a wellness tool for reflection, not a medical or psychological diagnosis, and it does not replace care from a qualified professional. It is written for the person taking it, it is not designed for hiring, and you can export or delete your data from your dashboard at any time.

For the narrower levels, the Wellington Membership is $4.99 a month. It adds the Portrait, 336 further questions across 4 chapters, bringing the report to 90 traits including every Big Five facet and all 24 character strengths, then adds a short weekly module toward all 255 traits across eight domains. The methodology shows what the writing looks like and has the scoring in full.

Questions people ask

How long does a Big Five personality test take?
Anywhere from two minutes to about forty, depending on how many questions it asks. A ten-item measure takes under two minutes and returns the five domains only. Sixty items takes about ten minutes and can support facets. Three hundred items measures thirty narrower traits with more items each. Past the first few dozen items, extra length mainly buys detail rather than better domain scores.
Is there a free Big Five personality test?
Several good ones. The IPIP-NEO is built from public-domain items that anyone may use and reports all thirty facets (Goldberg et al., 2006; Johnson, 2014). The BFI-2 reports fifteen facets beneath the five domains (Soto & John, 2017) and is available at no cost for research and educational use. Free versions of the ten-item TIPI exist too, though its own authors rate it below longer measures (Gosling et al., 2003).
What is a good score on the Big Five?
There is not one. Each dimension has advantages and costs at both ends, and which matters depends on the life you are living and the situation you are in. High Conscientiousness helps with long projects and can make it hard to stop working. Low Agreeableness is awkward socially and useful in a negotiation. Read the profile for fit, not for a total.
How often should I retake a Big Five test?
Once a year is plenty for tracking, and a few weeks is enough if you want to check a result you doubted. Small movements between sittings are normal and usually reflect mood, wording or the reference sample rather than change in you. Real trait change is gradual and shows up over years, not between two sittings a fortnight apart.
