DISC Personality Test

The DISC personality test and all contemporary DISC assessments are based on the research of William Moulton Marston. In 1928, he published the book titled Emotions of Normal People and introduced the DISC theory, where he classified four categories of human behavior known as the DISC Personality Types: Dominance, Influence, Steadiness, Compliance. While Marston mentioned that a person had a primary “style”, he noted that a person’s behavior was made up of a little portion of every style.

It’s important to note that Marston did not develop an assessment. The history of DISC testing begins with Walter V. Clarke, who built a test for personnel selection. In 1951, John Cleaver developed his own assessment, Self DISCription, intended for selection of a person for a certain job based on their behavior. This assessment evolved into a 24, four-adjective, forced-choice “question” instrument. It is widely used with minor changes today.
