What does DiSC stand for?
Everything DiSC assessments use the following descriptors: Dominance (D), influence (i), Steadiness (S), and Conscientiousness (C). However, Everything DiSC assessments allow for finer differentiation among styles than just four labels. So some styles will be D, i, S or C; but there are also styles such as Di or SC. When you complete an Everything DiSC questionnaire you are scored on eight scales, not four.
How long does it take to complete the disc assessment?
It takes only 15-20 minutes to take an Everything DiSC assessment. You’ll be asked about 80 questions. Because it uses adaptive testing, not everyone receives the same questions or number of questions.
What’s the best job for each DiSC style?
You may have noticed that you see more of one dimension over another when you deliver Everything DiSC to different types of groups. Maybe construction seems to have more Ds or the most C-styles are in the accounting department. This does occur, but the distribution of successful people in each dimension is still pretty evenly distributed.
For example, people in sales tend to be show up in the i quadrant, but they are also found in the other three. For more information see pages 82-84 of the Everything DiSC Manual.
DiSC is not recommended for pre-employment screening because it does not measure a specific skill, aptitude or factor specific to any position. Personality assessments should only be one of many factors considered in the employment decision.
DiSC is not a predictive assessment so assumptions should not be made regarding an applicant’s probability of success based solely on their style.
We recommend using a pre-hire assessment validated for selection, such as PXT Select.
Can your DiSC profile change over time?
In general, the average person’s profile tends to stay fairly consistent over time. While small differences in results from one time to the next may occur, major shifts in style are unlikely. However, if it has been two years or more since you last took the assessment or a major life event has occurred, we recommend taking it again to ensure the most accurate and up-to-date information.
“Stability refers to the assessment’s ability to yield the same measurements over a period of time. … A sample of 599 respondents took the DiSC assessment twice with a two-week interval between testings. … [D]ata suggests that the DiSC scales are stable over repeated administration. Consequently, test takers and test administrators should, on average, expect no more than small changes when the instrument is taken at different times. As the period between administrations increases, however; the divergent results of these administrations will become more and more noticeable.”
Do different cultures or nationalities tend toward one DiSC style?
Regarding geography and culture, Mark Scullard, a psychometrician and DiSC researcher, had this to say recently in a LinkedIn forum:
We don’t see much difference in DiSC results based on region of the U.S. In fact, I had just done a comparison using some representative states (CA, DC, FL, IA, NY, OH, TX, CO, GA) and found very few differences. There was a very slight tendency for results like more S styles in Ohio or more D styles in Georgia, but these differences are so small that they have virtually no practical implications.
With regard to ethnic difference, we can also say that we don’t see any differences based on the traditionally defined five U.S. categories. In fact, when we look at a large sample of Australians (living in Australia) who have taken the U.S. profile, they look the same as the U.S. population. I would only expect to see a difference in your sample with a large Latin-American population if participants are not very fluent in English. In such a case, the distribution of scores shouldn’t change, but the precision will drop a little.
The Everything DiSC blog (formerly published by Inscape Publishing) noted the following in their “How many D’s are there in the population?” post:
A person is only D relative to the people around her. A person is only C relative to the people around her. For example, imagine that we a have a plane full of S-style folks and the plane crashes on a remote island. We, of course, would have an island full of very, very polite people. But imagine that isolated community of people 10 years later, once they got to know each other really well. Some of those people would now probably be considered D’s – because they are more dominant relative to everyone else. If DiSC is going to be useful, it must help us understand our individual differences, not what everyone has in common.
The Everything DiSC profiles show a dot for your style and shading to show your comfort zone. If a person scores high for priorities outside the three surrounding his or her style, shaded lines will be shown. In the example to the right, this person has five priorities rather than the more typical three. Approximately one-third of respondents will receive an extra priority or two in their report.
How do you facilitate DiSC profile?
DiSC certification for trainers
Certification is not required to administer the DiSC Classic or Everything DiSC profiles. Everything DiSC Workplace certification training by Wiley, the publisher of Everything DiSC. Online instruction is available as is classroom training in Minneapolis, Minn. For certification in other countries, we can put you in touch with our international partners.
Facilitation kits are available for all DiSC profiles assessments. Use their scripted modules, videos, and other resources to create your own customized training program.

Who created DiSC profile?
The DISC Model of Behavior was first proposed by William Moulton Marston, a physiological psychologist with a Ph.D. from Harvard. His 1928 book, Emotions of Normal People, explains his theory on how normal human emotions lead to behavioral differences among groups of people and how a person’s behavior might change over time. His work focused on directly observable and measurable psychological phenomena.
There’s a long history from DiSC model to Everything DiSC profiles.
Walter V. Clarke, an industrial psychologist, was the first person to build an assessment instrument (personality profile test) using Marston’s theories. He developed an assessment instrument for John Cleaver called Self Discription.
Self Discription was used by John Geier, Ph.D., to create the original Personal Profile System® (PPS) in the 1970s.
Inscape Publishing improved this instrument’s reliability by adding new items and removing non-functioning items. The new assessment was named the Personal Profile System 2800 Series (PPS 2800) and was first published in 1994. This self-scored and self-interpreted assessment is now known as DiSC® Classic.
The Everything DiSC® product family, launched by Inscape Publishing in 2007, was created to make the DiSC assessment even more valuable to its users. It introduced more highly personalized reports, customizable facilitation tools and electronic access to unlimited follow-up reports.
The publisher of DiSC® assessments, Wiley (formerly Inscape Publishing), is committed to maintaining the highest standards of instrument development and application through careful research and development processes.
From the Everything DiSC Manual:
People agree with the narrative descriptions of their styles.
“Overall, participants report that the DiSC fit is good or excellent approximately 90% of the time. As documented under the Forer effect (1949), however, it is not unusual for participants to show a high level of agreement with psychological test results, especially when those results include broad interpretations that could accurately describe most individuals in the population.”
Observers also show agreement.
“… a study was conducted to examine the relationship between DiSC assessment results and observer ratings of leadership behavior. … The results of the analysis were largely as expected under the theoretical DiSC model. For 71% of the [leadership] practices, the expected style had the highest mean. For 88% of the practices, the expected style was among the top two highest means.”
All Everything DiSC® instruments offer valid scores and accurate feedback to the respondent. Each instrument is designed to provide reasonably accurate interpretations or feedback based on individual scores.
