You've probably heard of DISC tests, DISC assessments, or DISC profiles, but are they all the same? What is the purpose of DISC and DISC tools? DISC Assessments are behavioral assessment tools.

The DISC model is a tool for self-awareness. In addition, the DISC model lets us identify the styles of others. Once we know our style, the style of others, then we can change our behaviors to improve interactions. DISC refers to the four core sets of behavioral styles. The DISC assessment helps individuals, teams, and organizations make better decisions.
