Overview
The Big Five Personality Test uses the public-domain 50-item IPIP Big-Five Factor Markers (Goldberg, 1992) to measure the five broad dimensions of personality — often remembered by the acronym OCEAN.
What it measures
- Openness to experience — imagination, curiosity, and interest in new ideas.
- Conscientiousness — organization, dependability, and self-discipline.
- Extraversion — sociability, energy, and enthusiasm around others.
- Agreeableness — warmth, empathy, and cooperation.
- Neuroticism (emotional reactivity) — tendency toward stress, worry, and mood swings.
How it is scored
Each dimension is measured by 10 statements rated on a 1–5 scale (very inaccurate to very accurate), giving a score between 10 and 50 per dimension. Several items are reverse-scored. Higher scores mean more of that trait. Your report shows each of the five dimensions separately with low (below 24), average (24–37), and high (38 and above) reference bands.
There are no “good” or “bad” personalities — each trait is simply a spectrum, and most people fall in the middle range on most dimensions. This is an educational self-reflection tool, not a clinical or diagnostic test.

Frequently asked questions
What is the Big Five personality test?
The Big Five (also called the Five Factor Model or OCEAN) is the most widely used scientific model of personality. This version uses the public-domain 50-item IPIP Big-Five Factor Markers to measure five broad traits: openness, conscientiousness, extraversion, agreeableness, and neuroticism.
How is the Big Five test scored?
Each of the five traits is measured by 10 statements rated from 1 (very inaccurate) to 5 (very accurate), giving a score from 10 to 50 per trait. Some items are reverse-scored. Your LuriaLab report shows each trait separately with low (below 24), average (24–37), and high (38 and above) reference bands.
Is a high or low score better?
Neither. There are no “good” or “bad” personalities — each trait is a spectrum, and most people fall in the middle on most traits. The Big Five simply describes tendencies, not strengths or weaknesses.
Is this the same as a Myers-Briggs (MBTI) test?
No. Unlike the MBTI, which sorts people into 16 fixed types, the Big Five measures five continuous traits and is far better supported by scientific research. It describes where you fall on each dimension rather than assigning a single type.
Is the Big Five test free and anonymous?
Yes. The test is completely free, requires no sign-up, and can be taken anonymously. It is an educational self-reflection tool, not a clinical or diagnostic assessment.
