Group exercises, and what the assessor is writing down
What assessors write down during a group exercise, the four contributions that score, and why talking most is consistently marked down.
The short answer: In a group exercise the assessor is not watching the discussion; they are watching you, with a checklist, recording specific behaviours against competencies. That is why talking the most consistently scores badly and why silence scores worse. Four contributions reliably earn marks: bringing in someone who has not spoken, summarising where the group has got to, introducing a consideration nobody has raised, and moving the group toward a decision when time is short. None of them requires dominating, and all four are available to a quiet person. The task itself almost never matters — groups that fail to complete it routinely contain candidates who all passed.
Key points
- The assessor is scoring individuals, not the group, and the group outcome is rarely part of the mark.
- Talking most is consistently marked down; contributing nothing is marked lower still.
- Four specific contributions score: including others, summarising, adding a missing consideration, and driving to a decision.
- Time management is visible and scored — a group that runs out of time with no conclusion has been watched doing it.
What the assessor is actually writing down
Picture the sheet: your name, a list of competencies down the side, and space for observed behaviours. The assessor writes down things you did — "brought in Priya at 12 minutes", "proposed a structure", "restated the objective when the group drifted" — and maps them to competencies afterwards.
Two consequences follow. Contributions have to be observable, so a good idea you did not voice is worth nothing. And they have to be attributable, so nodding along with a strong point does not score for you even if you agreed with it first.
The four contributions that score
What to say, and what it evidences| Move | What it sounds like | Evidences |
|---|
| Bring someone in | "We have not heard from you — what do you think about the second option?" | Collaboration, awareness of others |
| Summarise | "So we agree on A and B, and the open question is C." | Structure, listening, judgement |
| Add a missing consideration | "We have covered cost — has anyone thought about what this does to the customer?" | Commercial awareness, analysis |
| Drive to a decision | "We have eight minutes. Shall we take option two and use the rest on the risks?" | Time management, decisiveness |
Each takes under fifteen seconds. Four of them across a thirty-minute exercise is a strong performance and represents perhaps a minute of speaking, which is why this is entirely accessible to someone who finds group settings difficult.
The clock, which almost nobody watches
Groups reliably spend two-thirds of the available time on the first third of the task and then rush. Assessors watch this happen in exercise after exercise, which makes the candidate who manages time visible for a reason unrelated to the content.
- At the start: "We have thirty minutes — shall we spend ten understanding the options and twenty deciding?" A structure proposed in the first minute is worth more than the same structure at minute fifteen.
- At the halfway point: "We are halfway — are we on track?" Fifteen seconds, and it is recorded.
- With a quarter left: "We have eight minutes. What do we need to agree to have something to present?"
None of this requires expertise in the task, which is why it is the most reliable way to score in an exercise about a subject you know nothing about. It also happens to make the group perform better, which is the point of scoring it.
The same competencies are being marked in every other exercise that day, in different formats — the format guide sets out how they connect.
One structural feature is worth using rather than resenting: many group exercises give each participant slightly different information, so no one person can see the whole problem. That is deliberate, and it means the group cannot succeed unless information is pooled. Saying "I have something on the third option that I do not think anyone else has — shall I share it?" is both the correct move for the task and a directly scoreable contribution.
The corollary is that withholding an advantage does not work. A candidate who notices they hold the decisive piece of information and saves it for a dramatic moment is competing when the exercise is measuring collaboration, and assessors have seen it many times. Share early, attribute clearly, and let the group's use of it be the thing you are marked on.
Frequently asked questions
Should I try to lead the group?
Do not appoint yourself leader, and do not compete for the role. Assessors see self-appointed chairs constantly and mark the behaviour rather than the title. What scores is leadership behaviour — noticing the group is stuck and proposing a way forward, watching the clock, making sure a quiet person is heard — which anyone can do from any position in the group.
What if another candidate dominates?
Do not compete with them and do not visibly resent them; both are scored and neither helps. Use the inclusion move instead: "I want to check we have heard from everyone — what do you think?" It scores for you, it redistributes the airtime, and it is the single most effective response available. The dominant candidate is usually being marked down without your assistance.
Does the group need to finish the task?
Not usually, and tasks are frequently designed to be unfinishable in the time. What is scored is how you worked, not whether the output was complete. Noticing at the two-thirds point that the group needs to converge, and saying so, scores considerably better than quietly completing the task with no one having heard from you.
