General DiSC® questions
Can my DiSC profile change over time?
The average person’s profile tends to stay fairly consistent over time. While you may find small differences in your results from one time taking the assessment to the next, you’re unlikely to experience major shifts in style. However, if it's been two years or more since you last took the profile or you've been through a major life change, we recommend taking it again to ensure the most accurate and up-to-date information.
What's the distribution of DiSC styles?
Everything DiSC is normed so there is an even distribution of styles.

Why is there a small i in DiSC?
The use of a lowercase i in DiSC is one way to distinguish Everything DiSC® and DiSC® Classic from other assessments that are based on the DISC model. The DISC model couldn't be trademarked, but the assessment and resulting report could. The little i is part of the trademark.
Do the colors of each DiSC style mean anything?
The colors themselves are not representative or relevant to the actual styles in any way. They are design and branding choices that differentiate Everything DiSC from other assessments.
Inscape (now Wiley) was the first to use the circumplex model (variables are arranged in two-dimensional space into a circular array and along two orthogonal axes) and they chose colors to visually differentiate the styles. They show how someone has aspects of each style. It's obvious through the color shading that someone with an i-style also has a little bit of D, S, and C.
Are there differences in DiSC styles based on heritage or gender?
The "relationship between heritage and inclination is of little practical importance. An ANOVA comparing men and women on inclination also produced statistically significant results at p <.01. Gender differences, however, accounted for less than 1% of the variance."

How long does it take to take the DiSC test?
It takes about 15 minutes to complete the questionnaire. You'll answer approximately 80 questions for an Everything DiSC assessment. Computerized adaptive testing is used so you could have more or fewer questions depending on how many answers are needed to determine your style.
DiSC Classic uses a 28-item forced choice questionnaire and it can take longer to complete.
Where can I find a copy of my DiSC profile?
We do not keep copies of your profile(s). However you can reprint your profile if you return to the email that provided the link to the assessment. Click on it and follow instructions to return to your report. Or better yet, sign into MyEverythingDiSC.com and add your report there so you can always find it easily. You'll still need the code from the initial email or from the cover of your report.
For administrators of Everything DiSC®
How should learners answer the questions? Should they think about themselves in the workplace, in a social situation, or in general?
Many factors affect a person's profile results and the response focus is not a significant one. However, if you're administering the assessment in a work setting there's no harm in asking the respondent to answer questions with that setting in mind. Our environment (e.g., at work, at home, with friends) does play an important role in our understanding of DiSC. But how we apply insights gained from profiles is much more the issue, not in how the profiles are constructed from respondents' answers.
Do I need to be certified to administer the DiSC profiles?
No, you do not have to be certified to administer DiSC profiles. However, the publisher does offer certification for those who wish to be certified.
Which assessment should I use for part of the hiring process?
Is DiSC available in languages other than English?
What does the DiSC assessment questionnaire look like?
The question format varies depending on the DiSC product family. Learn more about the questionnaire.
What is a DiSC Group Culture Report?
The DiSC Group Culture Report describes all profiles in your selected group of participants. The report includes an illustration of the group's distribution of DiSC styles and detailed information on how each individual's style may affect the culture of the group or organization. You can add respondents to your Group Report up to three times. Review sample group and facilitator reports.
What is the difference between DiSC Classic paper and DiSC Classic 2.0?
DiSC Classic Paper is an all-in-one 20-page booklet to respond, score and interpret results. The booklet describes the person’s primary DiSC style and helps identify one of the 15 DiSC Classical Patterns. The product was formerly known as DiSC Personal Profile System® 2800 Series.
DiSC Classic 2.0 is a 23-page, online report. It includes all the information of the paper booklet. In addition, it offers personalized feedback written in an informal and conversational style that helps people understand the strengths and challenges of their behavioral styles. A Group Culture Report is available when using DiSC Classic 2.0.
What is the best DiSC profile to use for leadership development?
Validity of assessments
How valid and reliable are DiSC® instruments?
Wiley, the publisher of all of our DiSC assessments, is committed to maintaining the highest standards of instrument development and application through a careful research and development process. They ensure all of the instruments offer valid scores and accurate feedback to the respondent. Each instrument is designed to provide reasonably accurate interpretations or feedback based on your scores.
Isn't there an adaptive style?
Wiley has conducted two studies that did not show any support for the theory that we can measure both a natural and an adaptive style. Their research report states, "In essence, there has never been well-documented support that any of the graphs are indicators of the private, public, natural, or pressured self or that they are anything other than measurements of general self-concept." (Read more at What about adaptive styles
Though everyone is a blend of all four styles, most people tend strongly toward one or two styles. A dot’s distance from the edge of the circle shows how naturally inclined a person is to encompass the characteristics of his or her DiSC style. Being adaptable, or flexing one's style, is something every style can do.
