E-Tray and In-Tray Exercises: How They Are Scored and What Assessors Mark

An in-tray and an e-tray are the same exercise with different plumbing. You are handed a role, a stack of work that cannot be finished in the time available, and a set of reference documents that quietly settle most of the decisions you are about to make. What separates a strong performance from an average one is almost never reading speed. It is knowing which of the two scoring streams you are in at any moment, and spending your minutes accordingly.

The same exercise, two sets of plumbing

The in-tray is the older format: a physical or downloadable pack of memos, letters, phone messages and reports, worked through with a pen. American employers usually call it an in-basket exercise, and the term shows up in Australian and Dutch recruitment too. The e-tray is the browser version, with a message list, a reading pane and a countdown on screen. The competencies being sampled are identical. The mechanics are not, and the mechanics change your tactics.

Two scoring streams, and they reward opposite behaviour

This is why an e-tray with twenty decision items and one written reply is not twenty-one items of equal weight. Work out roughly what the written response is worth, take those minutes off the top and protect them. Candidates who hand back an unfinished written answer because they were still triaging at the forty-minute mark lose far more than the two or three low-value items they would have cleared.

Prioritisation: the framework everyone brings, and why it stalls

Most candidates arrive with the urgent and important matrix in their head, and it collapses within five minutes. Every message in the pack has been written to look urgent. Senders assert deadlines, mark things high priority, and copy in someone senior. The matrix cannot sort items whose urgency is self-declared, so you end up with everything in one quadrant and no rule to break the tie.

What does discriminate is a short set of questions you can ask of any item in about ten seconds:

• What happens if this is still untouched at the end of the day? Consequence of delay is the real axis. A missed regulatory notification and an unanswered request for a meeting room feel equally noisy in an inbox and are three orders of magnitude apart here.
• Is anyone else blocked until I respond? Items that unblock other people are usually cheap to action and disproportionately credited, because they demonstrate that you understand your own work is not the only work.
• Is this mine to decide? The brief states your authority. Deciding something above your level and escalating something inside it are both scored errors, and the pack normally contains one of each.
• Has a document already decided it? A policy line, a budget figure or a contract date in the reference pack often removes the judgement entirely. Finding it is faster than reasoning about it, and answers that ignore it are marked down even when the instinct was sensible.

That gives a default order you can commit to in advance: anything legal, regulatory or safety-related, then external commitments falling due today, then items blocking other people, then substantive work with genuine slack, then the loud item that only needs a holding reply. Decide it before the timer starts so you are not inventing a policy while the clock runs.

The trap: doing the work instead of directing it

The single most common way to lose marks in either format is to be productive. The pack gives you a deputy, a team, a supplier, a colleague who has offered to help. Under time pressure, drafting the report yourself feels like progress, and it is the part of the exercise you can fully control. It is also the part that demonstrates the wrong competency. The role you have been given is nearly always supervisory, and the mark sheet has a delegation line on it that stays empty while you type.

Delegation is not the word "delegate" next to a name. Assessors are looking for a handover a real colleague could act on without coming back to ask what you meant.

Two mirror-image errors sit either side of this. Sending a decision upward that the brief gave you reads as avoidance, and it is the error more common among candidates who are anxious about overstepping. Hoarding everything reads as an inability to prioritise, and it is more common among candidates who are good at the work. Both are visible in the same moment on the mark sheet, which is why the brief tells you your authority in the first paragraph.

What the inbox format lets you show, and what it hides

This matters more than candidates expect. In a group exercise or a role play, an assessor watches you think. In an in-tray or an e-tray, the only evidence of your judgement is text you typed. There is no tone of voice, no clarifying question, nobody to notice that you spotted the contradiction and decided it was not worth raising. If it is not written down, it did not happen.

Four practical consequences:

• Make the reasoning explicit, briefly. One line per item: why this, why now, why them. It converts an invisible decision into scoreable evidence and costs you about eight seconds.
• Name what you are deliberately not doing. A short note saying which items you deprioritised and when you would return to them reads as control. Silent omissions read as running out of road, and the two look identical unless you write the difference.
• Write to the recipient, not to the assessor. Every item has one audience. A reply to a regulator, a client, your manager and a direct report are four different documents in register and length, and rubrics almost always carry an audience line. A detailed technical explanation sent to an angry customer scores badly whatever its content.
• Lead with the recommendation. First line, what you propose. Then two or three reasons that cite the documents by name. Then the risk and the next step. Assessors mark whether the reader could act on it without a follow-up conversation, and a reply that builds up to its conclusion fails that test even when the conclusion is right.

The format also has a ceiling, and knowing it saves you from arguing with it. Where the response options are fixed, you cannot propose the better fifth answer you thought of. Take the least-bad option, and where a free-text box exists, put your reservation there. Where no box exists, take the partial credit and move on rather than spending ninety seconds resenting the question.

What the inbox genuinely cannot sample is negotiation, persuasion and reading a room. That is not an oversight in the design, it is why the same assessment day runs a group exercise and a role play alongside it. The exercises are chosen so that each competency is observed in at least two different formats before anyone is rated.

The last five minutes are the cheapest marks on the paper

Whatever state you are in, stop working the inbox with five minutes left and do two things. First, check any figure you quoted against the document it came from, because a number that contradicts the pack costs an attention-to-detail mark that is otherwise free. Second, write a short summary: what you actioned, what you delegated and to whom, what you deferred and until when, and what you did not reach. It takes two minutes and it is usually the clearest single piece of evidence you leave behind.

How to practise so that it transfers

Untimed practice rehearses the wrong skill. The only real difficulty in either format is the mismatch between the volume of work and the clock, and working through a pack at leisure teaches you nothing about that. Run it against a real countdown, then check two things afterwards: how many of the deciding facts in the reference pack you actually used, and how many minutes the written response really needed compared with what you budgeted.

CogniPrep runs timed e-tray and in-tray scenarios with a role brief, reference documents that stay open, an inbox and a per-competency score, with the written items marked against a rubric. The full exercise set covers the rest of the day as well, which is the part most candidates leave until last.
