Extended DISC Assessments

Learn how your team prefers to interact with others.


What is DISC?

DISC is a behavioral model developed in the 1920s by Dr. Carl Jung and Dr. William Marston. Jung recognized that people could be divided into four main groups, and Marston later labeled them Dominance, Influence, Steadiness, and Correctness.

The DISC framework helps employees and leaders avoid:

  • Frustrating prospects and customers that lead to lost revenue.
  • Energy draining tasks and conversations that lead to burnout.
  • Demotivating or angering fellow team members.
  • Feeling disappointed, frustrated, and tired at the end of the day.


Participants who engage in the DISC assessment and corresponding coaching and train learn that their success is often determined by how well they communicate with other, and they learn how to more effectively adapt their communication styles to match the needs of others, including prospects, customers, coworkers, and managers.

Extended DISC® is a suite of online DISC assessments that identify individuals’ hard-wired DISC style. The results are tailored to your unique needs and preferences based on a wide selection of job roles. Sandler and Extended DISC have been strategic partners for over ten years.

Why Use Extended DISC Assessments?

Your personal and professional success in life is largely determined by how well you interact with other people. You have probably noticed it is very easy to get along with certain people. You almost instantly and effortlessly understand the other person because communication flows. But with most people, communication takes more effort. It is sometimes hard to understand where the other person is coming from, what they want, and what their intentions are.

Meanwhile, the other person may experience the same uncomfortable feeling. The outcomes of the interaction are not what you want. It takes energy, effort, and concentration. Still, the results are not what you hoped they would be.


With DISC Training, you and your team will learn to:


  • Understand how people communicate and operate differently.
  • Develop confident self-awareness of strengths and weaknesses.
  • Identify the preferred styles of others.
  • Modify their behavior based on the other person’s style to communicate more effectively.

It should only take about 15-20 minutes of each person’s time to complete the assessment, and the results will help you and the team get on the same page with regards to your internal and external communication.

As you learn about the four DISC Styles, please keep in mind that none of the styles are better or worse and that all styles have strengths and development areas-they just happen to be different. Our style does not limit what we can accomplish or how successful we can be. It simply predicts how we tend to do things. We can find all the four styles represented by very successful people; however, the most successful people know who they are, and they modify their style appropriately with different styles of people and in different situations.

Take the next step.

The journey to success starts where you are, and it starts today!
