Scientific inventories
Validated frameworks, ready to use

Big Five (OCEAN)
The most widely used personality model in academic research. Predicts life outcomes from career success to relationship quality.
NEO PI-R
The gold standard clinical personality instrument. 240 items, 30 facets across the five major personality domains.
RIASEC / Holland Codes
Vocational personality model that maps interests to career types. Used in career counselling worldwide.
Custom inventories
