Presentation Exercise Tips for Assessment Centres
A presentation exercise is marked on whether the panel takes your point, not on how polished the slides are. Most candidates prepare the wrong half.
Presentation exercises come in two forms. Either you are given a brief on the day, with twenty to forty minutes to prepare a short presentation, or you are asked in advance to prepare something and bring it. The on-the-day version is far more common at graduate assessment centres, and it is the one that catches people out, because the constraint is preparation time rather than public speaking.
A panel of one to three assessors watches, then asks questions. The questions are part of the exercise and are often where the judgement competency is scored: they are testing whether you understand the material well enough to defend it, and whether you can say "I do not know, here is how I would find out" without falling apart.
Technical schemes frequently add a twist by asking you to explain something specialist to a non-specialist audience, for example how a machine learning model reached its recommendation, to a panel with no data science background. There the entire mark sits in translation: what you left out, the analogy you chose, and whether you checked they were following.

What the panel is marking
One clear message
If the panel cannot say in a sentence what you were arguing, the presentation did not land. Decide the single message before you plan anything else.
Structure the audience can follow
Message, two or three supporting reasons with evidence, risks, and an explicit ask. Signposting where you are going is worth as much as the content.
Audience awareness
Pitching at the right level, cutting the detail the panel does not need and checking understanding at the right moments. This is the whole exercise when you are presenting to non-specialists.
Use of the brief
Evidence from the pack, correctly quoted. Presentations built on general opinion rather than the material provided score poorly however confidently delivered.
Timing
Overrunning gets you cut off, usually before your recommendation. Assessors treat coming in on time as evidence of planning, because it is.
Handling questions
Listening to the whole question, answering the one asked, and conceding ground where the challenge is fair. Bluffing is transparent to a panel who know the material.
Building a presentation in twenty minutes
- 1
Spend five minutes deciding the message
Write one sentence: what you want the panel to agree to. Everything else is chosen for whether it supports that sentence. Candidates who skip this produce a tour of the pack instead of an argument.
- 2
Pick exactly three supporting points
Three is what an audience retains in under ten minutes, and it forces you to leave out the interesting material that does not serve the message.
- 3
Attach one piece of evidence to each
A figure, a date, a quote from the brief. One per point is enough, and it is what separates a presentation from an opinion.
- 4
Write the opening and closing lines out
Only those two. The opening stops you starting with an apology, and the closing makes sure you end with the ask rather than trailing off.
- 5
Keep slides or flipchart minimal
Where visuals are allowed, headline plus one chart or six words a slide. Reading your slides aloud is the fastest way to lose the delivery marks.
- 6
Rehearse the timing once, out loud
Even a single run-through tells you whether you are at six minutes or fourteen. Use whatever is left of the prep window for this rather than for more content.
- 7
Predict three questions and prepare answers
The weakest point in your argument, the cost or risk you skated over, and the alternative you rejected. Panels ask these, and having thought about them shows.
Mistakes that cost marks
Summarising the brief
A narrated walk through the pack with no position is the most common weak presentation. The panel gave you the pack; they want your conclusion.
Too much content for the time
Trying to cover eight points in seven minutes produces a rushed delivery and no retained message. Cut ruthlessly during prep.
Reading the slides
Slides are for the audience, notes are for you. Dense slides read aloud lose marks for both structure and delivery.
No ask at the end
Finishing on "so those are the options" wastes the strongest moment you have. Say what you recommend and what you want the panel to do.
Defending the indefensible in questions
When a challenge is right, saying so and adjusting is scored as strength. Doubling down is scored as poor judgement.
Jargon with a non-specialist panel
On technical briefs, unexplained terminology is the failure mode. If you would not use the word with a new colleague from another team, translate it.

Frequently asked questions
How long should an assessment centre presentation be?
Usually five to ten minutes, stated in the brief, with questions after. Plan to finish slightly early: being cut off before your recommendation is worse than leaving thirty seconds unused.
Will I have slides?
Sometimes. On-the-day exercises often give you a flipchart or paper, occasionally a laptop. Prepared presentations usually allow slides. Either way the visuals are a support, not the deliverable.
Should I hand out anything?
Only if the brief invites it. A single page with your recommendation and the key figures can be effective, but it competes for the panel’s attention while you speak.
What if I do not know the answer to a question?
Say that, then say how you would find out and what you would do in the meantime. Panels mark that far higher than a confident guess they can see through.
How do I present well to a panel with no technical background?
Lead with the decision they need to make, use one analogy, state the confidence level and the main limitation in plain terms, and check understanding once in the middle. Assessors are scoring translation, not depth.
How can I practise a presentation exercise alone?
CogniPrep presentation scenarios give you the brief and the audience and mark what assessors mark: the structure and content decisions you take, scored against an expert key, and the plan or speaking notes you write, marked by AI against a rubric.
The rest of the assessment day
Assessment days rarely run one exercise in isolation. Most pair the exercises with an interview and an aptitude test, and many run a situational judgement test as part of the earlier sift. Our employer guides set out what specific companies run at each stage.
