Group Exercise at Graduate Assessment Centres UK: Formats, Examples and How to Prepare
What a group exercise at a graduate assessment centre is
Targetjobs describes the exercise as a way “to see your communication and problem-solving skills in action” and to check you can work effectively in a team (targetjobs, Aug 2026; reported). Prospects adds that assessors, usually a mix of HR consultants and line managers, score your actions against a competency framework, and that groups are typically six to eight candidates (Prospects; reported). It usually sits alongside other tasks covered in our graduate assessment centre guide, such as the e-tray exercise and online tests.
A warning on Fast Stream. The current Civil Service Fast Stream Assessment Centre has three exercises: a Written Exercise, an Oral Briefing Exercise and a Personal Development Conversation, with no group exercise (official). Many older guides still describe the 2021 group exercise as current. We use the 2021 version below only as a dated, official worked example. See our Fast Stream assessment centre guide for the current process.
Group exercise formats: pick yours
Targetjobs lists the common formats (reported). Choose one to see what to expect and the one habit that helps most.
Official worked example: the 2021 Fast Stream group exercise
The Civil Service archived guide is the most detailed official description of a group exercise we could verify. It is the 2021 guide, since replaced, so treat the numbers as an illustration of the format, not a current rule (FSAC Guide 2021, official).
| Element | What the 2021 guide said |
|---|---|
| Preparation | 25 minutes alone to prepare |
| Discussion | Up to 35 minutes, depending on group size, to agree one recommendation |
| Group size | 4, 5 or 6 candidates |
| Your role | Strongly support one option (first preference) and support a second option; shared brief for everyone |
| Chair | Candidates were told not to appoint a chair |
| Assessed on | Making Effective Decisions, Working Together, Communicating and Influencing |
“It’s really important to remember that this isn’t a competition.”
Stephen Dick, Fast Streamer, in the 2021 FSAC guide (one person’s account; source).
What assessors look at
The current Fast Stream centre scores candidates against four dimensions: Think (gather and analyse information, keep the bigger picture in mind), Relate (engage with others, influence perspectives, contribute to teamwork), Adapt and Strive (official). Other employers use their own frameworks; for example PwC publishes behaviours that it says are considered throughout selection, but does not name a group exercise on its process page (PwC, official). Check your employer’s own page or our guides for PwC, Deloitte, EY and Lloyds Banking Group.
Targetjobs adds an important point: you are “not being primarily assessed on whether you reach the ‘right’ answer” but on how you work with others (reported).
Airtime calculator: how much should you speak?
If everyone spoke equally, you would speak for about 5m 50s in total. A sensible target: 4 to 6 clear contributions, one of them a summary or a question that brings a quieter person in.
This is our illustration of fair share, not an employer rule.Preparation and mistakes to avoid
- Follow the brief. The 2021 guide says to keep to the information in the briefs and not to introduce assertions that contradict the evidence (official, archived).
- Cooperate, do not compete. The same guide says to seek cooperative relationships “rather than try to score points off each other” (official, archived).
- Contribute without dominating. Targetjobs advises being assertive, not aggressive, drawing out quieter members and summarising progress (reported).
- Take a role only if you can do it well. Volunteering as timekeeper or notetaker is fine, but you still need to contribute (reported).
- Watch the clock. Official Fast Stream guidance says its exercises need you to work reasonably quickly.
- Practise. Prospects suggests mock centres and practice with friends (reported). Read quality news before discussion-style groups (reported).
Common mistakes: interrupting, staying silent, treating it as a contest, inventing facts that contradict the brief, and dwelling on a bad earlier exercise. The Fast Stream chief assessor said no single part of the assessment will rule you in or out (2021 guide).
Virtual group exercises
Online versions often use breakout rooms and a “raise hand” function, and smaller groups can give each candidate more say (targetjobs; reported). Some employers drop the group exercise virtually and test the same skills in interviews, so prepare for both. In the 2021 Fast Stream exercise the group met on Google Meet and the guide asked candidates to join from a quiet room with stable WiFi and a charged laptop (official, archived).

Group exercise FAQ
How long is a group exercise?
There is no universal length. The only employer-stated figures we could verify are from the archived 2021 Fast Stream exercise: 25 minutes of preparation and up to 35 minutes of discussion. Targetjobs and Prospects give no standard duration (reported).
Do you have to be the leader?
No. Many exercises are leaderless and targetjobs says no one is designated leader in assigned-role tasks (reported). Assessors score behaviours, so influencing without chairing can score well.
What if the group is too loud?
Use a short, calm contribution that moves the group forward, such as a summary or a question. Targetjobs warns against aggressive behaviour (reported).
Does the current Fast Stream have a group exercise?
No. The current centre has a Written Exercise, an Oral Briefing Exercise and a Personal Development Conversation (official).
Is a group exercise a competition?
No. The 2021 Fast Stream guide says candidates are assessed against an independent standard, so all or none of a group may be successful (official, archived).
