DISC is a behavioral assessment tool used to understand and categorize human behavior and communication styles. It is based on a theory developed by psychologist William Moulton Marston in the 1920s. The DISC model identifies four primary personality traits, represented by the acronym DISC:

1. **Dominance (D)**: Individuals with a high Dominance score tend to be assertive, results-oriented, and competitive. They are often seen as strong leaders and decision-makers who seek control and challenges.

2. **Influence (I)**: Those who score high in Influence are typically social, outgoing, and persuasive. They excel in communication, enjoy working with others, and often inspire enthusiasm within their teams.

3. **Steadiness (S)**: Individuals with a high Steadiness score are generally calm, supportive, and reliable. They value harmony and collaboration, preferring stable environments and building strong relationships.

4. **Conscientiousness (C)**: Those who score high in Conscientiousness are detail-oriented, analytical, and systematic. They prioritize accuracy and quality, often focusing on tasks and processes to achieve results.

The DISC assessment helps individuals and organizations identify their own and others' behavioral styles, improving communication, teamwork, and conflict resolution. By understanding these styles, people can adapt their approaches to enhance collaboration and productivity in both personal and professional settings. The tool is widely used in various contexts, including leadership development, team building, and personal growth initiatives.
