In-Tray Exercise Practice and Tips
An in-tray hands you a desk of memos, letters and messages. The marks are in the order you choose, what you delegate, and why.
An in-tray exercise is the traditional form of inbox triage. You take a role, receive a pack of memos, letters, phone messages and reports, and decide what to do with each one within a time limit. Many versions ask you to record not just your decision but your reasoning, and the reasoning is frequently worth more than the ordering.
The skills assessed are identical to the e-tray: prioritisation, judgement, written communication and attention to detail. What differs is the mechanics. Paper packs are easier to spread out and cross-reference than a browser inbox, and they tend to lean harder on delegation, because the pack usually gives you a team and an organisation chart you are expected to use.
Some employers run an in-tray as a discussion exercise, where you complete it alone and then justify your decisions to an assessor. If your invitation mentions a follow-up discussion, prepare to defend your ordering out loud, because that conversation is where the judgement competency is actually scored.
In-Tray Exercise scenarios you can practise
Each one is timed, set in a named sector and scored against an expert key, with AI feedback on the written answers. Sign up to play the free sample in full.
In-Tray: Office Manager
You return from leave to a full in-tray as office manager of a busy charity. Sort memos, letters and requests, decide what to action and in what order.
Corporate & Business · 45 minutes
In-Tray: Ward Coordinator
You return to the coordination desk of a busy hospital ward to a full in-tray, with the ward manager off until tomorrow. Triage a safety hazard, a confidentiality slip, a staffing shortfall and more. Decide what to action and in what order.
Public Sector · 45 minutes
In-Tray: Depot Supervisor
You start an early shift as depot supervisor to a full in-tray of notes and messages. Handle safety hazards, driver-hours compliance, a late key customer and staffing gaps, safely and in the right order.
Corporate & Business · 45 minutes
In-Tray: Client Operations Desk (Asset Management)
You are a graduate analyst on the client operations desk of an asset manager. A trade error, a reconciliation break, an 11:00 client review and a journalist all land at once. Escalate honestly, protect the client and route everything through the right channel.

What an in-tray is scored on
Prioritisation with a stated reason
The order matters, and the explanation matters more. Two candidates with the same ordering score differently when one can name the principle behind it.
Delegation
The pack gives you a team for a reason. Assessors credit passing the right work to the right person with the context they need, and penalise both hoarding everything and dumping work without instructions.
Recognising what is not urgent
Loud items that can wait are planted deliberately. Deferring one with a note about when you will handle it is stronger evidence than dealing with it immediately.
Cross-referencing the pack
Two items usually relate: a memo that changes the deadline in a letter, a report that contradicts a claim. Spotting the link is one of the most reliable markers of a strong performance.
Written quality on the items you action
Short notes, replies and instructions are still marked for clarity, audience and tone. Brevity is fine; vagueness is not.
Composure about incompleteness
The pack is bigger than the time. A clear account of the items you did not reach and what should happen to them reads as control, which is exactly the behaviour being sampled.
Working an in-tray pack
- 1
Read the role and the org chart first
You need to know what you are allowed to decide and who works for you before you can triage anything. In an in-tray this is usually the difference between a good and a mediocre performance.
- 2
Sort into four piles quickly
Do now, delegate, defer with a date, and no action needed. Physically sorting is faster than deliberating item by item and gives you a structure to explain afterwards.
- 3
Write the reason as you go
One short line per item: why now, why them, why later. If the exercise asks for a rationale you already have it, and if a discussion follows you can defend the whole pack from your own notes.
- 4
Delegate with instructions, not just names
Say what you want done, by when, and what to do if it goes wrong. Handing an item to a colleague with no brief is scored as avoidance rather than delegation.
- 5
Look for the two items that interact
Before you finalise, check for the pair that changes each other. Assessors put it in to separate the candidates who read the pack as a whole from those who processed it in sequence.
- 6
Reserve time for a summary
End with what you actioned, what you delegated, what you deferred and what you could not reach. It takes two minutes and it is the clearest evidence of judgement you can leave behind.
Mistakes that cost marks
Doing everything yourself
With a team in the pack, refusing to delegate is a scored weakness rather than diligence.
Delegating the decision you own
The reverse error. Items inside your stated authority should be decided by you, and passing them up looks like avoidance.
Ordering without reasoning
A list of numbers with no rationale gives an assessor nothing to credit. Say the principle.
Missing the policy or budget line
The pack contains a constraint that rules out the obvious answer on at least one item. Acting against it costs the judgement mark.
Spending too long on item one
A beautifully handled first item and eight untouched ones scores poorly. Move at a pace that gets you through the pack.
Practising without a clock
The only real difficulty is the time. Untimed practice rehearses the wrong skill entirely.

Frequently asked questions
Is an in-tray the same as an in-basket exercise?
Yes. In-basket is the more common term in US hiring and in-tray in the UK and Australia. Both describe working through a pack of workplace items and deciding what to do with each.
Will I have to justify my decisions afterwards?
Sometimes. Some employers run the in-tray as a standalone written exercise and others follow it with a short discussion where you explain your ordering. Writing your rationale as you go covers both.
How much should I write per item?
Enough to be actionable: a sentence or two for most items, a short paragraph for anything you are replying to properly. Assessors are not marking volume.
What if two items seem equally urgent?
Say so and give the principle you used to break the tie, such as external commitment over internal request, or regulatory over commercial. A stated tie-break is itself evidence of judgement.
Do in-tray exercises still come up, or is everything digital now?
Both are in use. Digital delivery is now more common, particularly at virtual assessment centres, but paper in-trays persist, and public sector and operational roles still use them.
How can I practise an in-tray on my own?
CogniPrep in-tray scenarios present the same pack of memos and messages with a brief, a countdown and decisions scored against an expert key, plus written items 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.
