What is the DISC Assessment and DISC Personality Types?

The DiSC personality model is a powerful assessment tool that enhances teamwork, communication, and productivity in the workplace. Adopted by over one million people every year, it is utilised by organisations and facilitators to drive cultural change and foster enduring behavioural transformations.

By understanding diverse communication styles and motivational factors, DiSC lays the groundwork for a harmonious and efficient work environment. Let’s take a closer look at the four DiSC personality types and why you should use the DiSC test in the workplace.

What is the DiSC Personality Model?

The DISC Personality Model has undergone significant changes since its inception in the 20th century. While the original concept behind DISC originated from the research of the psychologist William Moulton Marston, Wiley has dedicated over 40 years to studying and analyzing DISC.

Interestingly, Wiley’s DiSC Classic paper profile was the very first DISC assessment ever created. Marston initially discussed the fundamentals of DISC in his 1928 book, Emotions of Normal People. He identified four core emotions and their associated behaviors, which are now widely recognized as Dominance (D), Influence (i), Steadiness (S), and Conscientiousness (C).

Over time, various tools have been developed to measure these traits. For instance, the Everything DiSC assessment employs a circle, or circumplex, to illustrate the connections and interactions between these personality types in a clear and straightforward manner.

The 4 DiSC Model Personality Types

DiSC is an acronym for the four distinct personality types. It identifies: Dominance, Influence, Steadiness, and Conscientiousness. Each of the 4 DiSC personality types represents a specific set of behaviors that manifest in different ways when interacting with others.

D: Dominance

A person with D-style personality places emphasis on achieving results and “seeing the bigger picture.” They are confident, occasionally direct, outspoken, and expectant. These individuals are often high achievers who prioritize advancing in any situation.

People with this personality type prefer to lead rather than follow and are renowned for their robust decision-making skills. Their inclination towards questioning the status quo and propelling change makes them vital in roles requiring clear direction and a results-focused mindset.

I: Influence

A person with Influence personality can easily persuade others. They tend to be assertive, enthusiastic, optimistic, open, trusting, and energetic. They excel in environments where teamwork, collaboration, and communication are key.

Individuals that have Influence as a dominant personality are skilled at building relationships and often inspire others with their lively spirit. Their natural social skills and ability to connect emotionally make them stand out in roles that require networking and the ability to motivate teams.

S: Steadiness

A person in this DiSC quadrant places a strong emphasis on cooperation, sincerity, loyalty, and dependability. They tend to have calm and deliberate dispositions, and they don’t like to be rushed. S-personalities balance out the more outgoing types and support those that are more analytical within their teams, providing stability and patience in high-pressure situations.

People with this DiSC personality style are dependable and excel in environments where they can offer support and don’t have to face frequent and sudden changes. Their preference for a methodical approach to tasks and a harmonious work environment make them highly valuable in roles that require meticulous attention to detail and a consistent routine.

C: Conscientiousness

C personalities place emphasis on quality and accuracy, expertise, and competency. They enjoy their independence and demand the details, often fearing being wrong. Moreover people with this personality are analytical, reserved, and systematic, with a keen eye for ensuring that everything is correct and in order. They thrive in environments that require precision and critical thinking, and they are meticulous with their work to avoid errors. C types are also cautious and thorough approach to tasks and decision-making makes them essential in roles that demand a high degree of accuracy and analytical skills.

DiSC Assessments

Why use DiSC Assessments?

DiSC personality assessments are leveraged as a strategic tool to enhance self-awareness and interpersonal relations within the framework of professional development.

Workplace culture

Strengthening workplace culture through DiSC assessments nurtures an atmosphere of mutual understanding and respect. By shedding light on individual behavioural differences and preferences, teams can navigate interpersonal dynamics more skilfully.

DiSC’s structured insights foster empathy, minimize conflict, and enhance collaboration. As a result, it cultivates an inclusive environment where diverse work styles come together to drive collective success.

Team building

Using the DiSC assessments can offer a nuanced framework for team building, shedding light on individuals’ strengths and preferences. Understanding the dominant personality type in each team member enhances the allocation of roles and maximises team cohesion.

This intentional approach enables teams to tackle challenges harmoniously, leveraging the unique contributions of each style. Consequently, this leads to more effective problem-solving and a boost in team morale.

Personal development

The utilization of DiSC assessments in personal development enables individuals to gain insight into their own behavioral tendencies and adaptability. Understanding one’s DiSC profile can lead to greater self-awareness, highlighting areas for growth and the potential for improved personal efficiency.

This tailored knowledge enables individuals to strategically navigate their career paths and interpersonal relationships with heightened self-regulation and emotional intelligence.

Leadership training

DiSC assessments are incredibly valuable in leadership training as they empower leaders to refine their communication and management styles in alignment with the diverse needs of their team.

By recognizing their own predominant personality and understanding those of their team, leaders can foster a more effective leadership approach, tailor their mentorship, and enhance decision-making processes. This cultivates a leader’s ability to support and drive a team’s performance adeptly, making DiSC an indispensable tool in leadership development.

Management training

In the realm of management training, DiSC assessments truly stand out by equipping managers with invaluable insights to effectively lead diverse teams. The precise nature of DiSC enables a deeper understanding of each team member’s intrinsic work style, prompting managers to tailor their managerial tactics and communication to resonate with various personalities.

This personalized approach plays a pivotal role in task delegation, conflict resolution, and performance appraisals, fostering an environment where team members can thrive and excel.

Facilitating DiSC

Facilitating DiSC within an organisation requires a considered and well-informed approach. Professionals entrusted with this role must possess a profound understanding of the four main personality types and the skills to effectively communicate its principles to participants. Workshops and training sessions centred on DiSC assessments often involve interactive activities that allow individuals to experience the practical applications of their insights. Facilitators play a vital role in guiding discussions, framing challenges, and fostering an environment where open feedback is encouraged.

This careful mediation ensures that participants not only comprehend their DiSC profiles but also learn to appreciate and leverage the diverse profiles of their colleagues. Through expert facilitation, teams emerge more united, and individuals more empowered, cementing DiSC’s value as a transformative tool in organisational development.

Conflict management

DiSC assessments play a vital role in conflict management by empowering individuals with an understanding of diverse communication styles. Recognising that conflicts often stem from misinterpretations and conflicting behavioural tendencies, DiSC enables team members to approach disputes with a perspective that aims for clarity and alignment.

Managers who apply DiSC principles can defuse tension and foster resolution by aligning their strategies with the inherent communication needs of each DiSC profile, thus creating a more harmonious and collaborative working environment.

Sales and customer service training

DiSC assessments play a crucial role in refining interpersonal skills that directly contribute to customer satisfaction and sales success. Individuals trained in DiSC principles and profound understanding of the charactersitics of the four personality types can learn to identify and adapt to the diverse communication styles of customers, allowing for more tailored and effective customer interactions.

Sales professionals can utilise this knowledge to enhance their persuasion techniques, while customer service representatives can address customer concerns more empathetically and efficiently. This adaptive approach leads to stronger customer relationships, increased customer loyalty, and ultimately, a more robust bottom line for businesses.

Hiring Staff


When it comes to hiring, DiSC assessments offer a valuable perspective to understand potential candidates. By understanding the DiSC profile of a position or team, employers can search for candidates whose behavioural styles complement or enhance the existing dynamics.

This approach to recruitment helps ensure alignment between a candidate’s natural tendencies and the role’s requirements, foreseeing potential synergies and areas for development. It’s a strategic move that can result in increased job satisfaction, reduced turnover, and a more dynamic team composition primed for success.

DiSC Assessment Reliability and Validity

DiSC is more than a behavioral assessment; it is a tool grounded in over forty years of empirical research and a legacy of publishing excellence carried by Wiley. With research as its foundation, Everything DiSC’s profiles are validated and their results published in multiple academic and professional arenas.


Reliability addresses the stability and consistency of the assessment tool – an instrument without significant random variation is considered reliable. The test-retest reliability of DiSC measures its stability by asking participants to complete the assessment multiple times over a period. The results showed an admirable median coefficient alpha of .87 and a median test-retest reliability of .86, surpassing the threshold of .70, which is widely regarded as good reliability.

Internal consistency is similarly robust within Everything DiSC, as evidenced by high correlations among items that are designed to measure the same construct. For instance, all items on the ‘D’ scale consistently measure ‘Dominance’, highlighted by a Cronbach’s alpha statistic that reflects this uniformity.


Validity examines the accuracy of the assessment – the extent to which DiSC actually measures what it claims to measure. Confirmatory analyses provide strong support to the tool’s validity. There are moderate positive correlations between adjacent scales and strong negative correlations between opposing scales within the DiSC model, reinforcing its structural integrity.

The circumplex representation of the DiSC assessment aligns with theoretical expectations, with support derived from multidimensional scaling, scale intercorrelations, and factor analysis. Further evidence of the assessment’s validity emerges from correlations between the Everything DiSC scales and well-established personality scales, such as the Revised NEO Personality Inventory™ and the Sixteen Personality Factor Questionnaire®, demonstrating the complementary nature of these tools and broad support for Everything DiSC’s claims.

DiSC Training

Effective DiSC training empowers individuals and teams with self-awareness and interpersonal insights, enabling a deeper understanding of their innate communication styles and those of their colleagues. It acts as a catalyst for improved efficiency within teams, fostering smoother collaboration by mitigating conflict and enhancing mutual understanding. Discovering one’s own personality traits and those of others equips employees with adaptability, nurturing a work environment where communicative mishaps are less frequent and more easily resolved.

Training activities designed around DiSC, such as role-playing different workplace scenarios, allow participants to practically apply their knowledge. This not only benefits personal development but also enhances team dynamics, leadership approaches, sales techniques, and recruitment and hiring strategies. DiSC’s versatile application makes it an invaluable resource across various corporate functions, streamlining the ways people interact and work together towards shared goals.


What is the purpose of the DiSC personality test?

The DiSC personality test is designed to help individuals understand themselves and others better by identifying their behavioral strengths and preferences. This understanding can enhance communication, teamwork, conflict management, leadership, and sales effectiveness.

By learning about one’s own DiSC style and those of others, individuals can tailor their interactions to be more collaborative and productive, leading to more effective workplace relationships and outcomes.

Which DiSC personality traits work best together?

While there is no one-size-fits-all answer to which DiSC personality traits work best together, each DiSC style has unique characteristics that can complement others. ‘D’ styles are often decisive and results-oriented, and they can be effective when paired with the more analytical ‘C’ styles who pay attention to quality and accuracy. ‘I’ styles offer enthusiasm and can foster a collaborative environment when paired with the supportive and empathetic ‘S’ styles.

Ultimately, the most effective teams often include a mix of DiSC styles, allowing the strengths of each to balance the weaknesses of others, creating a well-rounded and high-functioning team dynamic.

How do I know my DiSC personality type?

To determine your DiSC personality type, you will need to take the Everything DiSC assessment. The assessment consists of a series of questions that gauge your preferences and tendencies in various situations. Your answers create a personality profile that represents you on the DiSC model, categorizing you into one or more of the four core DiSC types: Dominance, Influence, Steadiness, and Conscientiousness.

The results provide a comprehensive report detailing your core tendencies, potential strengths, and areas where you might face challenges. Many organizations offer the Everything DiSC assessment as part of team-building or personal development programs. Alternatively, there are accredited providers that can administer the test for individuals seeking to discover their DiSC personality type on their own.

Can your DiSC style change over time?

Your DiSC style may exhibit slight variations over time due to personal growth, experience, or intentional effort to adapt your behavior in certain situations. However, the core aspects of your personality tend to remain stable. It is important to note that DiSC does not measure fixed traits; rather, it assesses behavioral preferences that can be flexible and context-dependent.

As an individual become more self-aware and experience various life changes or professional development, they may learn to leverage different aspects of their DiSC style more effectively. This adaptability can sometimes be perceived as a change in one’s DiSC style, but it is often more about the enhancement and management of one’s inherent behavioral patterns.
