Big Five IPIP-NEO-120 Test: 5 Domains and 30 Facets
The 120-question Big Five personality test: five domains, thirty facets, what to expect while answering, and how to read your results.
Dimensions rather than boxes
The Big Five describes personality traits along continuous dimensions. It does not assign a medical condition or a permanent category. A position on a dimension is not a grade of personal worth; it reflects how you describe yourself in this questionnaire.
IPIP-NEO-120: five domains and thirty facets
Johnson’s IPIP-NEO-120 explores five domains, each broken down into six facets of four statements. Facets show nuances that a single domain average can hide: someone can be very orderly without placing much emphasis on achievement, for example.
120 statements, at your own pace
Allow about 15 to 20 minutes. Statements appear in groups of five, with no time limit, and you can go back. Your answers stay only in this tab: keep it open until your results, because reloading clears the experience.
Answer based on how you generally are across situations, rather than how today went or how you would like to be. A thoughtful answer is more useful than a fast one.
How should you read your percentiles?
Each dimension and facet is expressed as a percentile: the 70th percentile means a score higher than 70% of people of the same sex and age group in Johnson’s (2014) reference sample. That is why the test asks for your age, and your sex if you wish. The band around the marker shows the measurement margin; it is wider for facets, which rest on four statements.
Some statements are reverse-scored, as explained in the calculation details. The test identifies sources and the French adaptation; this adaptation is not presented as a new independent validation.
