The DISC Assessment is a management tool used by the Fortune 500 companies to determine the behaviors of a person. Their accuracy rating is 84%, so what you learn about yourself is very solid. After taking a brief assessment, you receive a 45-page report that Dan then studies with you, so that definite changes in behavior can be made to help you get better and better. There are three different DISCS. One is for general leadership. The second is for salespeople. The third is for determining a career path.
