DISC Assessment

What It Measures

DISC measures behavioral style and communication preferences in four primary dimensions. Unlike personality assessments that focus on internal traits, DISC emphasizes observable behaviors and how people respond to their environment.

The Four Dimensions

1. D - Dominance (How you approach problems and challenges)

   • Direct, results-oriented, decisive
   • Focus: Getting results, taking action, solving problems
   • Motivation: Winning, competition, success

2. I - Influence (How you interact with and influence others)

   • Outgoing, enthusiastic, optimistic
   • Focus: Building relationships, persuading, collaboration
   • Motivation: Recognition, social approval, popularity

3. S - Steadiness (How you respond to pace and consistency)

   • Patient, consistent, supportive
   • Focus: Cooperation, reliability, stability
   • Motivation: Security, harmony, predictability

4. C - Conscientiousness (How you respond to rules and procedures)

   • Analytical, precise, systematic
   • Focus: Quality, accuracy, expertise
   • Motivation: Correctness, standards, order

Key Insights

Behavior Not Identity: DISC measures how you behave, not who you are.

Context Dependent: Your style may shift in different environments (work vs. home).

No Best Style: All styles are valuable and needed in organizations.
