Research, Reliability and Validity

Wiley is the leading publisher of DiSC assessments and accompanying training programs. Over 30 years ago, they pioneered the creation of the first commercially available version of DiSC—from the textbook into the workplace. Today, Wiley DiSC products are used worldwide in thousands of organisations. Wiley is truly “The Source of Everything DiSC.

Wiley’s research and validation studies have made DiSC psychometric assessments reliable: you can confidently use them in any setting and context. Research reports are publicly available (see below) for reference.
