The distribution of successful people in each DiSC quadrant is actually pretty even. People in sales do tend to show up in the i quadrant as you may expect, for example, but there are plenty of successful salespeople in the other three.
DiSC is not designed for pre-employment screening. It doesn’t measure a particular skill, aptitude, or specific factor for a position. It’s a personality assessment designed to facilitate teamwork and communication.
For employment screening, we recommend using a proven, pre-hire assessment validated for that purpose such as PXT Select.
