Our DISC Personality Assessment app is built on authentic psychological research. It is inspired by the pioneering theory of Dr. William Moulton Marston (Emotions of Normal People, 1928) and validated by modern DISC adaptations like the Everything DiSC model developed by Wiley Publishing.
Each question is crafted with scientific precision to ensure accurate reflection of real-world behaviors, leadership styles, and work preferences. This makes our app a trusted tool for personal growth, career planning, HR training, and relationship building.
Discover your Dominance, Influence, Steadiness, or Conscientiousness traits in minutes — based on decades of proven research and used by millions worldwide.
