DISC Test

Running a DISC session in 60 to 90 minutes

A session plan that turns the grid into a team conversation, with what to say and what is better avoided.

This plan works from the group grid: you open a session, everyone answers from the same link, and the grid updates as answers come in.

What DISC is, and what it is not

DISC goes back to William Marston's book Emotions of Normal People (1928), which described four ways of reacting to one's surroundings. Today's questionnaires, this one included, draw on that framework, and to our knowledge no freely available DISC questionnaire has solid academic norms.

In a workshop, it can work as a shared vocabulary: words that describe preferences, to say "we don't work the same way" without it sounding like blame. It supports a discussion; it does not measure the person.

What this questionnaire does not allow

  • saying how a person or the team will succeed;
  • building teams or assigning roles by profile;
  • comparing two people on the same axis: answers are forced-choice with a fixed total, so each person's four scores are read against each other, never against someone else's;
  • assessing, hiring or justifying a decision about someone;
  • reading DISC's C as Big Five Conscientiousness: no correspondence between the two has been established.

The session plan

  1. Minutes 0 to 10, the frame.

    State the goal: talking better, not ranking each other. Say that DISC supports a conversation, that a first name is optional and that nobody will have to announce their profile. Share the link or the QR code.

  2. Minutes 10 to 25, taking the test and reading alone.

    Everyone answers on their own, then reads their result page in silence and notes one sentence that fits them and one that does not.

  3. Minutes 25 to 40, the grid.

    Show the grid and first ask what people see in it, before any interpretation. Then read the make-up as questions: a frequent profile, a missing profile, a lone voice. Each reading is a hypothesis the group confirms or sets aside.

  4. Minutes 40 to 55, the discussion.

    Do the "where this profile got me wrong" exercise below, then ask this question: "In which recent situation did our way of working help us, and in which did it get in our way?"

  5. Minutes 55 to 60, the commitment.

    The group picks a single concrete action for the month, based on what was said, not on the colours. Whoever carries it volunteers: the grid does not appoint anyone.

  6. 90-minute variant.

    Between minute 40 and minute 70, work in sub-groups of three or four on a real team situation (a meeting, a recent decision): what was easy, what got stuck, and which DISC words help to say it? Each sub-group reports back in one sentence, then keep twenty minutes for the commitment.

The "where this profile got me wrong" exercise

Everyone rereads their description and picks out two sentences: the one that describes them least well, and the one that could describe almost anybody. Pool the second ones, without saying which profile they come from.

This is the Barnum effect, described by Bertram Forer in 1949: a general enough description feels personal to most people. Spotting it together is a reminder that the result is a starting point, and makes it legitimate not to recognise oneself in it.

Why start from a real situation

A meta-analysis of debriefs (Tannenbaum and Cerasoli, 2013) links going back together over a specific work episode with better performance afterwards, mostly in simulation studies (medical and military). It does not cover DISC or any profile tool: that is why one question in the plan starts from a real, recent situation, and this plan promises no effect on the team.

To avoid during the session

  • guessing or announcing out loud the profile of a colleague who has not shared it;
  • reading out to the group the first names from the facilitator-only list;
  • commenting on a pair of named people, or comparing two members on the same colour;
  • sharing out tasks or roles according to colours;
  • drawing from the grid a judgement on what the team is worth or will achieve.
