DiSC is a model of human behavior that helps people understand "why they do what they do." The dimensions of Dominance, influencing, Steadiness, and Conscientiousness make up the DiSC model and interact with other factors to describe human behavior.

Originally created by Dr. William Marston at Columbia University and researched and updated by Dr. John Geier and Inscape Publishing at the University of Minnesota, the DiSC model and its training assessments and various other tools have helped over 35 million people in 20+ languages over the last 40 years.

Organizations use DiSC in their training and coaching efforts as a performance improvement strategy. The most important benefit of the DiSC model is helping individuals understand themselves and others better.
