The five traits and 30 facets
Each trait is measured with 60 statements, ten for each of its six facets. These are the names used in your report:
Openness to experience
Curiosity about ideas, art, feelings and new experiences. Facets: imagination, artistic interests, emotionality, adventurousness, intellect and liberalism.
Conscientiousness
Self-discipline, order and working towards goals. Facets: self-efficacy, orderliness, dutifulness, achievement-striving, self-discipline and cautiousness.
Extraversion
Energy and positive emotions in the company of others. Facets: friendliness, gregariousness, assertiveness, activity level, excitement-seeking and cheerfulness.
Agreeableness
Concern for getting along with others. Facets: trust, morality, altruism, cooperation, modesty and sympathy.
Neuroticism
How easily you experience negative emotions. Facets: anxiety, anger, depression, self-consciousness, immoderation and vulnerability. A high score is not a diagnosis of a mental disorder.
What your results show
You get the same report as in the standard Big Five test, with scores based on all 300 answers. The example report shows the layout.
- An overview of the five traits, each with a 0–100 score, a low, average or high label and a percentile.
- A percentile comparison with people who answered the IPIP-NEO-120 online, by sex and age group if you wish.
- Your strongest, lowest and most balanced trait, an approximate five-letter SLOAN code and up to three facets that clearly break with their trait.
- A section for each trait with a description, a chart of its six facets and a short text for each facet. Each facet links to an in-depth article.
- A link you can share or download as a PDF, and the option to compare your profile with a friend or partner.
What does it measure?
The same five personality traits and 30 facets as the shorter Big Five test, with more questions per facet. It suits people who want to spend more time describing the nuances of their personality.
Where does it come from?
The full IPIP-NEO inventory uses Goldberg’s public-domain IPIP scales for constructs similar to those in the NEO personality inventories. John A. Johnson’s online work helped make this 300-item form widely available.
How is the result calculated?
Ten items contribute to each facet and 60 to each broad trait. Reverse-keyed answers are adjusted before scores are combined. The longer questionnaire samples each facet more extensively than the 120-item version. Scores are shown on a 0–100 scale with the same low, average and high limits as the standard test. Percentiles are calculated from the 120 statements this version shares with IPIP-NEO-120, so both versions are compared with the same online sample.
What can the result tell you?
More items do not remove self-report bias or guarantee an accurate judgement about an individual. This is the IPIP questionnaire, not the commercial NEO PI-R. The report describes tendencies and should be interpreted in context.
Languages and adaptations
Question wording comes from published IPIP translations where available, volunteer translations and our own translations. Coverage and wording vary by language. Our public research pages document the IPIP-NEO translations and their change history.
Frequently asked questions
Is the long version free, including the results?
Yes. You can answer all 300 statements and read the full report without paying or creating an account.
Should I take the 120 or the 300 version?
Both measure the same five traits and 30 facets, and the long version includes every statement in the 120-item test. With ten instead of four statements per facet, facet scores in the long version are more precise and less affected by a single answer. The broad trait scores usually differ little. The standard test takes about 10 minutes and suits most people; choose the long version if you want to look closely at your facets and can spend about half an hour.
Why are the percentiles based on 120 statements?
The comparison data from John A. Johnson’s online sample, about 410,000 people, cover the 120 statements in IPIP-NEO-120. To compare you with that sample on equal terms, the percentiles use your answers to those 120 statements. The 0–100 scores, levels and facet texts use all 300 answers.
Is this the NEO PI-R?
No. The NEO PI-R is a commercial questionnaire. IPIP-NEO uses public-domain IPIP statements written to measure similar traits and facets, so the names are similar, but the questions and scores are not the same.
How is it different from the HEXACO and Big Five Aspects tests?
The HEXACO test uses another model with six traits, including honesty-humility, and its emotionality and agreeableness are defined differently. The Big Five Aspects test keeps the five traits but splits each into two aspects instead of six facets. The quick personality test gives only a rough overview of six traits. The long Big Five test gives the most detailed picture of the 30 classic Big Five facets.
Can I take a break during the test?
Yes. Your answers are saved in this browser as you go, so you can close the page and continue later on the same device. Answer at your own pace, since tired or hurried answers make the result less useful.
