Big Five Personality Test
The Big Five personality model — also known as the Five-Factor Model or OCEAN — is the most widely validated framework in modern psychology for understanding human behaviour. It measures five core dimensions that shape how you think, work, lead, and relate to others: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism.
This free online assessment, developed by Dr. Nick Keca — an organisational psychologist with a Doctorate from Aston University — offers two modes: a 50-question quick diagnostic for immediate personality insights, or a comprehensive 120-question IPIP-NEO audit that maps all 30 sub-facets of your personality and identifies your leadership shadow profile.
Based on the research of Costa, McCrae, and Goldberg's International Personality Item Pool, your results include a personalised radar chart, trait-level analysis, environmental fit recommendations, and an Executive Shadow Matrix that flags potential leadership derailment risks.
