What the Big Five personality test measures
The Big Five, also called the five-factor model or OCEAN, is the most widely used framework in personality research. It describes personality through five broad traits, each a scale that runs from one end to the other rather than a category you either belong to or do not. This free Big Five test scores you on all five:
- Openness to Experience — how strongly you reach for imagination, novelty and ideas over the familiar and practical.
- Conscientiousness — how much you plan, organise and follow through.
- Extraversion — how much energy you draw from people, activity and attention.
- Agreeableness — how readily you cooperate, trust and make room for others.
- Neuroticism, which we call Emotional Reactivity — how strongly and how often you feel worry, stress and other difficult emotions.
How the test works
There are 50 statements, ten for each trait, and the test takes about seven minutes. Half of the statements are worded in reverse — agreeing with them counts against the trait — so a habit of agreeing with everything does not inflate your scores. You answer each on a five-point scale from strongly disagree to strongly agree.
No account is needed. Your answers are scored in your browser and are not sent to us; when you finish, only your five scores are kept, in a cookie on your device, for 30 days.
What your result shows
Your free result gives a score from 0 to 100 on each of the five traits, a band — low (0–33), moderate (34–66) or high (67–100) — and a short reading of what that band tends to look like. An optional full profile, part of a paid purchase, reads each trait in depth, including its trade-offs.
A score is your own answers averaged and rescaled, not a comparison with other people. A 70 on Extraversion means your answers leaned strongly toward extraverted statements; it does not mean you are more extraverted than 70% of the population. No trait is good or bad at either end — each end has its uses and its costs.
Big Five, HEXACO and type tests
Unlike a 16-type test, the Big Five does not sort you into a box: a moderate score is reported as moderate. HEXACO, the model behind our main personality test, keeps a close relative of these five traits and adds a sixth, Honesty-Humility. Take this test for a quick five-trait snapshot; take the main test for six axes, 24 narrower dimensions and an archetype.
This is a short self-report test. Ten statements per trait gives a useful snapshot but not the precision of longer research instruments, and it is not suitable for clinical use or for decisions about another person.
Questions about the Big Five test
What does OCEAN stand for?
OCEAN is an acronym for the five traits: Openness, Conscientiousness, Extraversion, Agreeableness and Neuroticism. Neuroticism is often renamed Emotional Stability (scored the other way) or, here, Emotional Reactivity.
Is this Big Five test free?
Yes. The test and your five scores, bands and short readings are free with no sign-up. Only the longer written profile is paid.
Is a high Neuroticism score bad?
No. It describes how strongly you tend to feel difficult emotions, not a disorder. People who score high often notice risks and problems early; the cost is carrying more stress. A self-report score is not a diagnosis, and if distress is affecting your life, a qualified professional is the right person to talk to.
Does personality change over time?
Broad traits are fairly stable in adulthood, but they do shift gradually, and your answers can also vary with mood and circumstance. Retaking the test some months apart is a reasonable way to see how much your own scores move.
