Big Five In-Depth Test | 30-Facet Profile (IPIP-120)

The in-depth Big Five assessment: built on the same 120-item IPIP item bank, it goes beyond a basic five-dimension Big Five test to deliver a complete facet-level report of the Five Factor Model across five broad domains — Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness — each broken down into six narrower facets, giving a total of 30 facet scores. It uses the public-domain IPIP-120 item set, which measures the Five Factor Model structure established by Costa and McCrae's NEO-PI-R.

About This Test

This assessment is a 120-item adaptation from the International Personality Item Pool (IPIP) that measures the Five Factor Model structure established by Costa and McCrae's NEO-PI-R: five broad domains — Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness — each with six facets. The NEO was originally created as a three-factor model assessing Neuroticism, Extraversion, and Openness. The revision — the NEO-PI-R — was published in the late 1980s and added two further factors, Agreeableness and Conscientiousness, completing the Five Factor Model (FFM). Costa and McCrae refer to the broad factors as domains and to the traits within them as facets, with six facets nested in each domain. This free test uses the public-domain IPIP-NEO-120 item set (Johnson, 2014), which measures the same 30 facets of the Five Factor Model and correlates strongly with the original instrument.

How It Works

You will respond to 120 statements using a five-point scale from Strongly disagree to Strongly agree. There are no right or wrong answers. Answer honestly, thinking about how you generally are rather than how you are in any single situation.

The Five Domains & 30 Facets

The assessment measures five domains — Neuroticism (N), Extraversion (E), Openness to Experience (O), Agreeableness (A), and Conscientiousness (C). Each domain contains six facets, such as Anxiety and Angry Hostility (Neuroticism), Warmth and Gregariousness (Extraversion), Fantasy and Aesthetics (Openness), Trust and Modesty (Agreeableness), and Competence and Self-Discipline (Conscientiousness).

Frequently Asked Questions

Have another question? Let us know.

What does this test measure?

This test measures the Five Factor Model (FFM) of personality — the structure established by Costa and McCrae's NEO-PI-R. It assesses five broad domains — Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness — as well as 30 narrower facets nested within them.

Is this the official NEO-PI-R?

The official NEO-PI-R is a commercial, copyrighted instrument published by Psychological Assessment Resources. This free test uses the public-domain IPIP-NEO-120 item set, which measures the same five domains and 30 facets and correlates strongly with the original.

How are my results computed?

For each of the 30 facets, your responses to the four related statements are averaged on a scale from 1 to 5. Each domain score is the average of its six facet scores.

How should I answer the questions?

There are no right or wrong answers. Answer honestly, based on how you generally are, not how you would like to be.
