DISC assessment

A DISC assessment is a behavioral self-assessment tool based on psychologist William Moulton Marston's DISC emotional and behavioral theory, first published in 1928. These assessments aim to improve job performance by categorizing individuals into four personality traits: dominance, inducement, submission, and compliance.

The scientific validity of the DISC assessment has been a topic of discussion among researchers and practitioners. While some psychologists question its predictive validity and place it outside mainstream personality theory, DISC remains widely used in business, coaching, and organizational development due to its accessibility and practical application. Supporters argue that, despite lacking the empirical rigor of models like the Big Five, DISC provides clear and actionable insights that enhance communication, teamwork, and self-awareness in workplace settings.
