DiSC® is the leading personal assessment tool used by over 1 million people every year to improve work productivity, teamwork and communication.
What is DiSC®?
The DiSC assessment, published by Wiley, is a non-judgmental tool used for discussion of people's behavioral differences. If you participate in a DiSC program, you'll be asked to complete a series of questions that produce a detailed report about your personality and behavior. You'll also receive tips related to working with people of other styles.
Note: Information here applies only to Everything DiSC and DiSC Classic assessments. It's likely that other tests using the name DISC have not been researched and validated to the depth of Wiley's DiSC products.
The DiSC® model provides a common language that people can use to better understand themselves and to adapt their behaviors with others — within a work team, a sales relationship, a leadership position, or other relationships.
DiSC profiles help you and your team:
- Increase your self-knowledge: how you respond to conflict, what motivates you, what causes you stress, and how you solve problems
- Improve working relationships by recognizing the communication needs of team members
- Facilitate better teamwork and teach productive conflict
- Develop stronger sales skills by identifying and responding to customer styles
- Manage more effectively by understanding the dispositions and priorities of employees and team members

Who created DISC?
Dr. William Marston, a physiological psychologist, who shared it in his book Emotions of Normal People, published in 1928. He did not create an assessment instrument from his theory. However, based on his model, others have created DISC assessments. That's why you might discover other DISC tests in the marketplace.
Look for the trademarked lowercase i in DiSC® to be sure you're looking at the assessment tool researched, validated, and published by Wiley.
