Big Five / OCEAN

The Big Five — Openness, Conscientiousness, Extraversion, Agreeableness, Emotional Stability (OCEAN) — is the most scientifically validated personality model available. Developed primarily by Robert McCrae and Paul Costa Jr., it rests on decades of cross-cultural studies. Unlike typologies (MBTI, Enneagram), the Big Five measures each trait on a continuous spectrum, yielding a more nuanced and predictively valid portrait. This assessment gives you a score on all 5 dimensions, a leadership-contextualised interpretation, and concrete development paths.

Frequently asked questions

What research is it based on?
The Big Five (OCEAN) model, developed primarily by Robert McCrae and Paul Costa Jr. from the 1980s. It is the most replicated and cross-culturally validated personality model in contemporary psychology — far ahead of MBTI or the Enneagram in empirical rigour.
How long does it take?
About 15 minutes for 40 to 50 questions. Take your time to answer honestly: Big Five traits are deep-seated, so spontaneous answers are generally more reliable than over-considered ones. The test can be paused and resumed — your progress is saved.
Is the result stable over time?
Big Five traits are remarkably stable in adulthood, with gradual shifts over years (a tendency toward greater conscientiousness and agreeableness with age). You can retake the test after 6-12 months to observe changes linked to your personal or professional context. Major life transitions — new role, parenting, relocation — can sometimes surface measurable shifts.
Can it be used for hiring?
No. Our tests are designed for personal and managerial development, not selection. Using a personality profile as a hiring criterion is legally risky and scientifically contested without a strict protocol. For formal HR use, engage a certified occupational psychologist.
