Methodology & sources
TypeAxis does not invent a private scoring science. We implement public, widely used standards and document them here.
Big Five (IPIP)
Personality items are from the public International Personality Item Pool (IPIP-50 Markers). Scoring follows official IPIP instructions: keyed +/− items, sum by domain, display scaled 0–100.
Holland’s RIASEC model
Holland’s RIASEC model (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) groups work activities into six interest themes. A Holland code is usually the top two or three themes for a person; occupations also have RIASEC profiles in O*NET. TypeAxis scores interests on a Like / Neutral / Dislike scale (1–3). High-point codes use a fixed tie-break order: I > A > S > E > C > R.

Career matching (O*NET)
Occupations and interest profiles come from the O*NET database Career Interest Types. Primary ranking uses cosine similarity between your RIASEC profile and each occupation's official interest vector. Attribution: U.S. Department of Labor, Employment and Training Administration — O*NET. TypeAxis is not endorsed by DOL/ETA.
Work Style Profile
Shareable TypeAxis labels derived from Big Five patterns. They complement—not replace—interest-based career ranking.
