DISC Test: Your Four Scores
25 forced-choice questions, and at the end your four scores: D, I, S and C
In 1928, William Marston identified four major behavioral styles that shape how you decide, communicate and collaborate. Here you answer 25 forced-choice questions: each time you pick the group of adjectives that describes you best. At the end you get all four scores, D, I, S and C, and the profile that leads in you, rather than a single letter. The limits of this format are written further down, including the tie rate we measure on our own results.
Based on the work of William Moulton Marston (1928)

About this test
The DISC model traces back to the work of American psychologist William Moulton Marston, published in 1928 in his book "Emotions of Normal People". Marston wanted to understand how people respond to their environment, and he identified four core behavioral tendencies: Dominance, Influence, Steadiness, and Conscientiousness. This theoretical framework was later developed into a professional assessment tool in the second half of the twentieth century, giving rise to the DISC test as it is used today. The four-color reading of DISC (red, yellow, green and blue) was popularized for a general audience by Swedish author Thomas Erikson in his 2014 bestseller "Surrounded by Idiots", which builds on this same model.
The test identifies your dominant color among four profiles: the Dominant (red), results-oriented, direct, and decisive; the Influential (yellow), communicative, enthusiastic, and energizing; the Steady (green), reliable, empathetic, and harmony-seeking; the Conscientious (blue), precise, analytical, and detail-focused. Most people show a mixed profile with one or two dominant colors.
Knowing your DISC profile has a concrete impact on how you work. You understand why certain colleagues seem slow or impulsive to you, you adapt your communication style to the person in front of you, and you identify your own behavioral blind spots. The DISC test is today one of the most widely used professional development tools in business, coaching, and recruiting to improve team cohesion and interpersonal communication.

Frequently Asked Questions
- The DISC test helps you understand your communication style, adapt your behavior to different people, and identify your strengths and blind spots at work. It is free and widely used in coaching, management, and recruiting to improve team cohesion, resolve interpersonal conflicts, and develop interpersonal intelligence.
- Yes, more often than you might think. We have not measured the test-retest reliability of this test, and a questionnaire like this one can produce a different profile from one sitting to the next, especially if your work situation has changed in between. What it captures is behavior adapted to a context, not a fixed nature. A Dominant can learn to listen more; a Steady can build assertiveness. Treat the result as a dated snapshot, not a label.
- About 5 minutes for 25 questions. Each question presents four adjectives and you choose the one that fits you best. Results are immediate, free, and require no sign-up: you get your dominant color profile along with an analysis of your behavior under pressure and your natural preferences.
