How our DISC assessment works, and how well it measures

1. Four scores. Each style has 10 statements. Two of them are worded in reverse, so that agreeing lowers the score; this stops a habit of always agreeing from pushing every score up. Your score for a style is the average of its 10 answers, from 1 to 5.
2. Style strength. We show each average as a number from 0 to 100 (1 becomes 0, 5 becomes 100). This is not a percentile. It does not compare you with other people.
3. Your letters. Your letters come from where your dot sits on the wheel (below). In one of the four style regions you get that one letter. In a region between two styles you get both letters, the higher score first: a dot between D and C with D 4.9 and C 4.5 gives "DC".
4. Earlier results. Results taken before this rule keep their original reading: the highest score first, and a second letter when the runner-up was within 0.4 points of it on the 1 to 5 scale.
5. Balanced. If all four scores sit less than 0.4 points apart, we call the result Balanced rather than naming a style your answers did not choose.
6. The wheel. Your dot uses all four scores at once. Its height shows how outgoing or reserved your answers are (D and I pull up, S and C pull down). Its left-right position shows whether your focus is more on tasks or more on people (D and C pull left, I and S pull right). The wheel has eight regions: the four styles and the four blends between neighbours.
7. Trial statements. From 27 October to 10 November 2026, some people taking the test also saw up to 32 extra trial statements. They helped us build the next version and did not count toward anyone's result. That round has ended, and today everyone answers the same 40 statements. A later round may add trial statements again; like these, they will not count toward anyone's result.

No AI writes your scores or your style.

• Of 93 people who retook it 24 hours or more after their first attempt (3 August to 9 November 2026), 55.9% got the same main style both times.
• Their scores themselves moved less than their style letters did. The correlation between first and second scores was D .61, I .70, S .56 and C .70.
• Across all 381 retakes, including those within minutes of the first, the figure was 51.7%.

Three things to keep in mind. First, 93 people is a small group, so the 55.9% could easily be several points higher or lower. Second, these people chose to retake, often because the first result surprised them, so this group is likely to be less stable than takers in general. Third, a change of main style usually happens when the top two scores are close: when two styles score within a few tenths of a point, a retake can swap their order. Read a close second as part of your style.

What we are doing: the next version shows how sure each result is, and we will publish a planned retest, not only self-chosen retakes.

The most common difference is mild: for example, letters "D" with the dot just inside the region between D and C. The rounding fault meant that when the runner-up was exactly 0.4 points behind, a computer rounding error sometimes counted the gap as slightly more than 0.4, so no second letter was added. We fixed it on 10 November 2026.

What we changed: your letters now come from where your dot sits on the wheel, so the letters and the dot always agree.

What changes

• Eight regions of the wheel are measured directly, each with its own statements, instead of four styles measured and four blends inferred.
• Every statement describes one behaviour at work, in plain words, with no "virtue" wording such as "loyal" or "high standards" that nearly everyone agrees with.
• C is written as the reserved, questioning style; S as the accommodating style; carefulness is no longer part of either.
• Your style name comes from your dot, so the words and the wheel always match.
• Each result shows how sure it is.

Where it stands

A first trial round collected 1,076 completed tests with 80 new statements (27 October to 9 November 2026). It confirmed the design: the eight regions fall in the expected order around the wheel. It also showed that four regions need better statements before the new version is reliable enough to release: the warm and accepting region (between I and S), the accommodating S region, the steady region (between S and C) and the questioning region (between C and D).

What it still needs

• About 30 new statements for those four regions.
• One more short collection round to test them.
• A public report of the results, to the same standard as this page, before the new version replaces this one.

We have not set a date. We will update this page when each step is done.

DISC tests share four letters but not their questions, so each one draws the line between styles in a slightly different place. Some tests ask you to rate each statement on its own, as ours does, while others make you choose between statements, which measures your styles only against each other. Some describe C as careful and others as reserved and questioning, so a careful but sociable person can come out differently on each. When two of your styles are close, any small difference in wording or format can swap their order. If two tests disagree, look at what both say about your strongest and weakest styles, which tend to stay the same.
