DISC is a group of psychometric tests based on the 1928 work of psychologist William Moulton Marston. The tests classify four aspects of personality by testing a person's preferences in word associations (compare with Myers-Briggs Type Indicator). DISC is an acronym for:

• Dominance - relating to control, power and assertiveness
• Influence - relating to social situations and communication
• Steadiness - relating to patience, persistence, and thoughtfulness
• Compliance (or conscientiousness or caution) - relating to structure and organization

These four dimensions can be grouped in a grid with D and I sharing the top row and representing extroverted aspects of the personality, and C and S below representing introverted aspects. D and C then share the left column and represent task-focused aspects, and I and S share the right column and represent social aspects.

An Internet version of the DISC can be taken online at TalentSmart.com.

The spelling using a lower-case i "DiSC" is a trademarked version of the test by Inscape Publishing. In addition, a complete DiSC history, advice on using DiSC, and the online sale of all DiSC tests, reports, and books, is available at SpecificAction.com.
