What is DISC?

DISC is often described as a "Personality Test". In reality, DISC is really more like a "personality profiling system" which is why we call our profiles the DISC Personality Profile.

A DISC Profile utilizes a method for understanding behavior, temperament, and personality. A DISC Profile provides a comprehensive overview of the way that people think, act, and interact. It is the most widely used profiling tool of its kind, and is supported by decades of validation and reliability studies.

The DISC Personality Profile is based on the work of renowned psychologist Dr. William Moulton Marston, and was introduced in his 1928 book "Emotions of Normal People" . William Marston, a contemporary of Carl Jung, developed the DISC Personality Profile after studying the personality traits, behavioral patterns, and instinctual reactions of thousands of individuals. As a result of his work, Marston developed the DISC assessment as a tool to measure four primary behavioral traits:

Dominant (D)
Direct, outspoken, results-oriented, a leader, problem-solver
Best characterized by: Donald Trump

Influencing (I)
Friendly, outgoing, talkative, optimistic, the life of the party, people-oriented
Best characterized by: Bill Clinton

Steady (S)
Team player, stable, consistent, maintains the status quo, peacemaker, family-oriented, patient
Best characterized by: Fred Rogers

Compliant (C)
Logical, organized, data-driven, methodical, perfectionist, detail-oriented
Best characterized by: Bill Gates

But he never actually developed a DISC Test or DISC Assessment to measure these 4 DISC Styles. In 1940, Walter Clark took the theory of William Moulton Marston and developed the first DISC Assessment. And, infact, it is still the same DISC Assessment that is still in use today!

DISC Personality Traits Breakdown The acronym "DISC" is taken from the first letter of each of these behavioral traits. Categorization as a D, I, S, or C is achieved through answering a short multiple-choice quiz designed to measure an individual’s natural responses in a variety of circumstances. The results of the quiz are used to create a personalized DISC Personality Profile, providing insight into a wide range of DISC Personality Traits and motivating factors.

Although most people will dominant in one of the four DISC Styles, the DISC Test scores participants in all four behavioral traits. This results in an in-depth personalized DISC Personality Profile that takes into consideration the unique ways that the four DISC Traits work together to influence personality and behavior.

Yes, the DISC Test can be used to determine a person’s primary personality type. But a DISC Personality Profile is much more than just a way to label and categorize personality. The DISC Personality Profile identifies patterns of behavior, and can be used to implement solutions for maximizing an individual’s strengths and minimizing weaknesses. The DISC Personality Profile is used in a wide variety of settings, including business, education, sales, coaching, and counselling. Primary applications of the DISC Personality Profile include: 

Strengthening communication skills
Building leadership abilities
Diffusing interpersonal conflict
Choosing attainable goals
Boosting performance and productivity
Increasing motivation
Strengthening workplace skills
Constructing strong teams
Cultivating productive work or study habits
Making smart hiring decisions

The DISC Test and DISC Assessment is used around the world, and is blind to gender, race, and age. Most importantly, a DISC Test and DISC Profile provides an impartial, constructive language to discuss the ways that people think, act, and interact.
