The World's Most Powerful DISC Assessment
A scientifically-validated behavioral assessment measuring four primary personality dimensions: Dominance, Influence, Steadiness, and Compliance. Based on Dr. William Marston's pioneering work, this assessment is currently utilized by 73% of Fortune 500 companies for team building, communication enhancement, and organizational development.




Assessment Overview
The DISC behavioral assessment employs rigorously validated psychometric methodology to categorize observable behavior patterns into four primary personality dimensions. This empirically-based framework provides actionable insights for interpersonal communication, team optimization, and professional development across diverse organizational contexts.
Four Empirically-Validated Dimensions
Dominance (D)
Results-oriented · Challenge-focused · Direct communication style
High-dominance individuals demonstrate strong correlation with executive decision-making capacity (r=.74, p<.001) and goal-oriented achievement behaviors. Characterized by direct communication patterns, competitive drive, and preference for autonomy in problem-solving contexts. Predictive validity established for leadership roles requiring rapid decision implementation.1,2
Influence (I)
People-focused · Collaborative · Persuasive communication
High-influence profiles demonstrate significant positive correlation with team cohesion metrics (r=.79, p<.001) and interpersonal effectiveness measures. These individuals excel in collaborative environments, exhibiting optimistic affect, strong verbal persuasion capabilities, and relationship-building competencies. Convergent validity established with emotional intelligence assessments.3,4
Steadiness (S)
Stability-seeking · Patient · Supportive team member
Steadiness dimension demonstrates strong predictive validity for employee retention (β=.68, p<.001) and team stability outcomes. Characterized by preference for consistent procedures, collaborative work environments, and supportive interpersonal dynamics. Individuals scoring high on this dimension show elevated patience indices and conflict-avoidance tendencies.5
Compliance (C)
Quality-focused · Analytical · Systematic approach
Compliance profiles correlate significantly with analytical problem-solving capacity (r=.81, p<.001) and attention to detail metrics. These individuals demonstrate preference for systematic methodologies, data-driven decision making, and quality assurance protocols. Strong discriminant validity from general cognitive ability measures confirms unique behavioral dimension.6
