The domain & facet model
The Five-Factor Model organizes personality into five broad domains. Each domain captures a general tendency, but two people with the same domain score can be quite different underneath. The IPIP-NEO-120 splits every domain into six facets — each scored from four items — so the report shows not just how high you are on a trait but which parts of it drive your score. A high Conscientiousness score that comes from Orderliness reads differently than one driven by Achievement-Striving.

Report includes
An overview of your five Big Five domain scores, each shown with a population percentile and a 90% confidence range, followed by the full 30-facet profile so you can see exactly which facets shape each domain. Scores are referenced against a large public-domain normative sample.
Facet scores are 4-item sums (range 4–20); domain scores are the mean of their six facet sums (range 4–20). The normative comparison comes from the Kajonius & Johnson (2019) public-domain release (N = 320,128). That sample is a large, self-selected online volunteer pool rather than a nationally representative survey, so percentiles should be read as a comparison against other online respondents, not the general population.
