DISC Personality Test

The DISC Personality Test is a free, 28-item self-report inventory from Science of Apps that takes about 6 minutes. It measures your behavioural style on the four DISC dimensions from William Moulton Marston's model — Dominance, Influence, Steadiness and Conscientiousness — with 28 forced-choice word groups in the classic DISC format, and gives your primary and secondary style with how you tend to communicate, decide and work with others. There are no right or wrong answers: answer every item to get your DISC Profile result card (SOA-DT), with your profile and what each scale means. It is based on Emotions of Normal People (William Moulton Marston (1928)).

Science of Apps offers a free DISC Personality Test, updated for 2026 and 2027. It measures dominance, influence, and steadiness and conscientiousness and how your style works with others and gives instant results with a shareable certificate.
