The 120-question Big Five test, with 30 facets
This in-depth assessment is built on the IPIP-NEO-120, a 120-item public-domain measure of the Five Factor Model developed and validated by psychologist John A. Johnson (2014). Where our 50-question quick test reports your five broad domains, this version measures each domain through its six underlying facets — 30 facet scores in total. That extra resolution is what separates a genuine Big Five assessment from a four-letter type quiz.
Why facets matter
Broad trait scores hide important differences. Two people can both score "high" on Conscientiousness for opposite reasons — one is meticulously orderly but not especially driven, the other intensely achievement-striving but disorganized. At the domain level they look identical; at the facet level they are clearly different people. Facets are where a Big Five profile becomes usable for real decisions about work, relationships, and habits.
The five domains and 30 facets
The test scores all five OCEAN domains and the six facets within each:
Openness to Experience
curiosity, imagination, and appetite for novelty
- Imagination
- Artistic Interests
- Emotionality
- Adventurousness
- Intellect
- Liberalism
Conscientiousness
organization, discipline, and dependability
- Self-Efficacy
- Orderliness
- Dutifulness
- Achievement-Striving
- Self-Discipline
- Cautiousness
Extraversion
sociability, assertiveness, and energy
- Friendliness
- Gregariousness
- Assertiveness
- Activity Level
- Excitement-Seeking
- Cheerfulness
Agreeableness
trust, cooperation, and compassion
- Trust
- Morality
- Altruism
- Cooperation
- Modesty
- Sympathy
Neuroticism
sensitivity to stress and negative emotion
- Anxiety
- Anger
- Depression
- Self-Consciousness
- Immoderation
- Vulnerability
How the test is scored
- You rate 120 short statements on a 5-point agree–disagree scale. Each facet is measured by four items, and each domain by 24.
- Roughly half the items are reverse-keyed to counter acquiescence bias (the tendency to just agree). Those items are automatically recoded before scoring.
- Facet and domain scores are computed and shown as low / average / high bands so you can read your profile at a glance. Scoring runs in your browser.
- Nothing is required to see your result — no email, no account, no paywall.

Where the questions come from
The items are drawn from the International Personality Item Pool (IPIP), a public-domain collection of personality items maintained for scientific use. The specific 120-item form and its facet scoring key come from Johnson's IPIP-NEO-120, which was built to approximate the commercial NEO PI-R while remaining free for anyone to use.

Frequently asked questions
What is the IPIP-NEO-120?
The IPIP-NEO-120 is a 120-item public-domain personality inventory that measures the five broad Big Five domains (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism) and the 30 narrower facets beneath them. It was developed and validated by psychologist John A. Johnson (2014) as a shorter form of the 300-item IPIP-NEO, drawn from the International Personality Item Pool. It is free to use for any purpose, including commercial use.
How is this different from a 50-question Big Five test?
A 50-item test (like the IPIP-50) reports only your five broad domain scores. The IPIP-NEO-120 uses roughly four items per facet to additionally break each domain into its six facets — 30 facet scores in total. Two people with an identical Conscientiousness score can have very different facet profiles (for example, high Orderliness but low Achievement-Striving), and only a facet-level test shows that.
Is the IPIP-NEO-120 scientifically valid?
Yes. The Big Five (Five Factor Model) is the most empirically supported framework in personality psychology, replicated across more than 50 cultures. The IPIP-NEO-120 is one of the most widely used open-source facet inventories in published research; validation studies report internal-consistency reliabilities around 0.80 at the domain level. It is designed to align closely with the commercial NEO PI-R while remaining free and public-domain.
Is the test free and anonymous?
Yes. It is completely free, needs no email or account, and there is no paywall. Your individual answers are processed in your browser; only summary scores are stored if you choose to save or share your result. The items come from the public-domain International Personality Item Pool.
How long does the in-depth test take?
About 15 minutes for 120 questions. Answer based on how you generally think, feel, and behave rather than how you wish to be. If you want a faster read, the 50-question quick test takes about 7 minutes and still gives accurate domain scores.
What are the 30 Big Five facets?
Each domain has six facets. Openness: Imagination, Artistic Interests, Emotionality, Adventurousness, Intellect, Liberalism. Conscientiousness: Self-Efficacy, Orderliness, Dutifulness, Achievement-Striving, Self-Discipline, Cautiousness. Extraversion: Friendliness, Gregariousness, Assertiveness, Activity Level, Excitement-Seeking, Cheerfulness. Agreeableness: Trust, Morality, Altruism, Cooperation, Modesty, Sympathy. Neuroticism: Anxiety, Anger, Depression, Self-Consciousness, Immoderation, Vulnerability.
