Why the Everything DiSC Assessment Works for Everyone, No Matter Their Culture

In today’s diverse world, understanding how people behave is key to working well together. The Everything DiSC assessment helps with this by categorising behaviours into four main styles: Dominance (D), Influence (I), Steadiness (S), and Conscientiousness (C). Some people wonder if this tool works equally well for everyone, no matter where they come from. Here, we’ll explain why the Everything DiSC assessment is accurate and reliable for people from all cultures.

Culture matters

What is the Everything DiSC Assessment?

The Everything DiSC assessment helps people understand their own and others' behaviour by placing them into four main categories: Dominance, Influence, Steadiness, and Conscientiousness. These categories help explain how people act in different situations and interact with others.

What Do Validity and Reliability Mean?

Validity - The test measures what it’s supposed to measure.

Reliability - The test gives consistent results every time it’s taken.

For an assessment to be useful, it needs to be both valid and reliable, no matter who is taking it. Everything DiSC is both of these. Everything DiSC Workplace® (English) has been DNV certified as an occupational test tool in North America and the United Kingdom. This means that the Workplace assessment has passed the Test Review Model developed by the European Federation of Psychologists’ Association (known as EFPA), helping learners make informed decisions about the quality and utility of an assessment.

Why the Everything DiSC Assessment is Valid for All Cultures

1. Built on Universal Ideas: The Everything DiSC assessment is based on well-researched ideas about human behaviour that apply to everyone, no matter where they’re from. Everyone shows behaviours like being assertive, sociable, or careful.

2. Same Behaviours Everywhere: The behaviours measured by the DiSC model (D, I, S, and C) are seen in all cultures. While people might show these behaviours differently based on their culture, the basic traits are the same.

3. Thorough Testing: The creators of the Everything DiSC assessment test it with people from many different backgrounds to make sure it works accurately for everyone.

4. Cultural Adjustments: The assessment uses “cultural norming,” which means it adjusts the scores based on cultural differences to give a fairer and more accurate result.

Why the Everything DiSC Assessment is Reliable for All Cultures

1. Consistent Results: Studies show that the Everything DiSC assessment gives consistent results, no matter the culture of the person taking it. This consistency proves the test is reliable.

2. Standard Testing: The same questions and instructions are given to everyone, ensuring fairness and consistency.

3. Ongoing Improvements: The creators of the Everything DiSC assessment keep updating and improving it, making sure it stays reliable for everyone.

A Helpful Analogy: How Many Tall People Are There in the World?

Think about asking, "How many tall people are there in the world?" The answer depends on what "tall" means in different cultures. In some countries, people might be considered tall if they are over 5'8", while in others, they might need to be over 6'2" to be considered tall. The definition of "tall" changes based on the cultural norm.

Similarly, the Everything DiSC assessment measures behaviours that exist everywhere, but how these behaviours are viewed can vary by culture. The assessment results don’t change, but how we interpret these behaviours might.

Making Sense of Cultural Differences

While the Everything DiSC assessment works for everyone, it's important to understand cultural differences when interpreting the results:

- Context Matters: Consider cultural norms and values when looking at the results.

- Training for Cultural Awareness: Teach leaders and employees about cultural differences to help them understand and respect various behaviours.

- Tailored Development: Create programmess that consider cultural differences to ensure everyone feels included and understood.


The Everything DiSC assessment is a powerful tool for understanding behaviour, and it works well for people from all cultures. Its foundation in universal behaviours, careful testing, and constant improvements make it both accurate and reliable. By being aware of cultural differences when interpreting the results, organisations can use this tool to improve communication, teamwork, and leadership in a diverse world.
