What the DISC measures
Based on the theories of Dr. William Moulton Marston, the DISC assessment measures how individuals express emotions through behavior. It does not measure intelligence, skills, or deep personality (like the Big Five); rather, it measures behavioral style and situational adaptation. It categorizes behavior along two axes: Active vs. Passive (Paced), and Task-Oriented vs. People-Oriented.
The dimensions it assesses
- D - Dominance (Active / Task-Oriented): Direct, results-oriented, firm, strong-willed, and forceful. Driven by results and challenged by problems.
- I - Influence (Active / People-Oriented): Outgoing, enthusiastic, optimistic, high-spirited, and lively. Driven by social recognition and relationships.
- S - Steadiness (Passive / People-Oriented): Even-tempered, accommodating, patient, humble, and tactful. Driven by cooperation and maintaining harmony.
- C - Conscientiousness (Passive / Task-Oriented): Analytical, reserved, precise, private, and systematic. Driven by quality, accuracy, and expertise.
What to do with your result
- Communicating with a High D: Be brief, to the point, and focus on results. Do not chitchat.
- Communicating with a High I: Allow time for socializing, focus on the "who", and use enthusiastic language.
- Communicating with a High S: Present changes slowly, provide reassurances, and speak calmly. Do not force immediate decisions.
- Communicating with a High C: Provide data, facts, and written documentation. Do not ask personal questions or demand emotional responses.
Common questions about the DISC
- What does the DISC measure?
- Behavioral styles and interpersonal communication preferences in the workplace.
- Can the DISC diagnose me?
- No. Working & Communication Style (DISC) is a screening questionnaire, not a diagnostic tool. It can flag that something may need a closer look. It cannot tell you what is causing it. It describes tendencies rather than diagnosing anything, and no result here is a condition or something to fix.
- Is this DISC test really free?
- Yes. No account, no email address, no payment. Psychometrics Today is funded by donations rather than advertising, which is also what allows us to publish instruments whose authors permit free but non-commercial use.
- Are my answers stored or shared?
- No. Your answers are scored inside your browser and never sent to us. There is no database of responses, because we never receive any. Closing the tab erases them, which is why results cannot be recovered afterwards.
- How often should I retake the DISC?
- Traits and preferences move slowly, so retaking this every few months is more informative than retaking it often. Larger shifts usually follow a genuine change in circumstances.
- How accurate is the DISC?
- Screening questionnaires are good at flagging that something merits attention and poor at establishing what it is. This one is sensitive to how you feel on the day you take it, and many instruments were validated on narrow populations whose cut-offs may not transfer cleanly to everyone. The references at the foot of this page are the primary sources.
- Why can I not take the DISC here?
- The DISC model may be described freely, but published DISC assessments are commercial products. We will not reproduce a questionnaire we have no right to reproduce, so this page explains what it measures instead. Write original behavioural-style items mapped to the four Marston quadrants and avoid vendor branding.
