Big Five Personality Test

The Big Five Personality Test is a free, 50-item self-report inventory from Science of Apps that takes about 10 minutes. It measures the Big Five personality traits — openness, conscientiousness, extraversion, agreeableness and neuroticism — with the 50-item IPIP Big-Five Factor Markers, the public-domain research inventory by Lewis R. Goldberg used in thousands of studies, scored the way the IPIP keys specify. There are no right or wrong answers: answer every item to get your Big Five Personality Profile result card (SOA-B5T), with your profile and what each scale means. It is based on IPIP 50-item Big-Five Factor Markers (public domain) (Lewis R. Goldberg, International Personality Item Pool).
