Job Simulation vs Traditional Aptitude Tests
How the publicjobs job simulation differs from traditional aptitude tests and what that means for your prep.
Most candidates preparing for a publicjobs.ie competition spend their time on numerical reasoning drills and verbal reasoning practice. That is not a bad use of time, but it is not the whole picture. The test that tends to separate people at Stage 1, and the one that generates the most “I have no idea how to prepare for this” posts on boards.ie, is a different animal entirely: the job simulation.
Understanding how it differs from a traditional aptitude test matters before you start prepping. If you treat them the same, you will prepare for the wrong thing.
This post covers the comparison. For a full guide to the job simulation format in the Irish context, see the public service job simulation test overview.
What is a traditional aptitude test?
A traditional aptitude test measures a specific cognitive ability in isolation. Numerical reasoning asks you to interpret data and calculate under time pressure. Verbal reasoning checks whether you can read a passage and draw accurate conclusions from it. Logical or abstract reasoning tests your ability to spot patterns.
These tests have a single correct answer per question. Speed and accuracy are what matter. You either get the number right or you do not.
They are useful screening tools - they tell an employer something real about your capacity to process information quickly and accurately. But they do not tell you anything about how a candidate would actually handle a working situation, which is exactly the gap the job simulation is designed to fill.
If you are working on the numerical side, numerical reasoning practice for Irish civil service competitions covers the Irish-specific format. The points below focus on the simulation component, where the preparation logic is fundamentally different.

What makes a job simulation different?
A job simulation puts you into a fictitious workplace scenario and asks you to respond as you would on the job. There is no single correct answer in the same way. Instead, responses are rated on how well they reflect the behaviours and values the employer is looking for.
For publicjobs.ie competitions, the job simulation component typically takes one of two forms.
An SJT presents a workplace scenario and asks you to evaluate actions. It may use ratings, a ranking order or a single-choice response; the competition instructions decide. PSP’s SJT banks use five independently rated actions on a six-point scale, with repeated values allowed.
The second is the e-tray, sometimes called the inbox exercise. You are given background materials for a fictitious organisation, then presented with a set of emails and tasks to respond to within a fixed time. According to publicjobs.ie materials, the e-tray can take up to two and a half hours and involves three stages: reading the context documents, selecting appropriate email responses, and writing a longer information response using the materials you have read. It is a sustained, document-heavy exercise that tests judgement, prioritisation, and written communication together rather than any one ability in isolation.
The SJT practice guide explains rating versus ranking, with original worked examples and a clear description of PSP practice scoring.
Why did Irish public service recruitment move this way?
The shift away from standalone ability tests toward a job simulation format is part of a broader change in how the Civil Service assesses candidates. The Civil Service Capability Framework, introduced in February 2024 and now applied across all major competitions, replaced the older Competency Model. Where the old model focused on demonstrable past behaviours in specific competency areas, the new framework assesses a wider set of seven elements: behaviours, skills, strengths, knowledge, values, motivation, and interests.
The job simulation is designed to surface several of those elements at once. A verbal reasoning test tells you something about one dimension. An e-tray exercise, done under time pressure with documents you have not seen before, gives the assessors a richer picture.
For candidates preparing now, that shift means the approach that worked well for an older-style competition, or for a UK civil service application, may not map cleanly to what is being assessed today.
Does the aptitude test portion still count?
This is a question that causes genuine confusion, and the honest answer is that the detail varies by competition and you should always check the candidate information booklet for the specific campaign you are entering.
That said, based on what candidates have reported from recent Executive Officer competitions, the numerical reasoning and verbal reasoning tests typically function as pass/fail gates at Stage 1 rather than contributing to your overall Order of Merit ranking. The job simulation component is where the scores that determine your place on the panel are generated. A separate written question, roughly 500 words in 30 minutes, is also reported by candidates to be pass/fail only.
The implication is significant. If you are spending 90% of your preparation time on numerical reasoning drills and neglecting the job simulation, you may be putting your energy into the part that matters less for your final ranking.
Note that PAS does not publish pass marks officially. Thresholds reported by candidates on forums suggest a qualifying score in the region of 370 out of 800 for some competitions, but this is not confirmed and it varies. Do not treat any figure you find online as guaranteed fact. Check publicjobs.ie or the candidate booklet for the campaign you are entering.

What does good preparation look like for the job simulation?
For the aptitude tests, standard timed practice works. You are developing speed and accuracy with a fixed question type, and repetition helps.
Judgement practice asks you to evaluate a response rather than calculate a number. Look at the evidence, the person’s authority and the consequences of the action. Use the capability framework for your grade as context, without assuming it supplies a universal answer key.
Useful preparation for the job simulation includes:
- Reading the Capability Framework itself, specifically the level descriptors for the grade you are applying to. The publicjobs.ie website publishes these and they are worth the time.
- Practising the response method in your invitation, and reviewing the reasoning behind each action.
- For the e-tray, practising document-reading and structured written responses under a time limit. If you have never done an inbox exercise under pressure, the format itself will slow you down.
Frequently asked questions
What is the difference between a job simulation and a situational judgement test?
An SJT is one kind of workplace simulation. An inbox or e-tray exercise may instead involve documents, prioritisation or written responses. These labels do not establish a universal format. Read the instructions for your own competition.
Is the job simulation harder than the aptitude test?
“Harder” depends on your starting point. The aptitude tests are straightforward to practise for: the question types are defined, and speed improves with repetition. The job simulation is harder to prepare for without the right material, because generic practice packs are rarely built around Irish Civil Service scenarios or the 2024 Capability Framework. Candidates who have gone through the process often describe the job simulation as the component they felt least ready for, not because it is intellectually harder, but because there was less obvious, relevant practice available.
Do I get my job simulation score back after the test?
Based on what candidates have reported from recent competitions, PAS does issue individual scores and the qualifying score for each test after results are released. You will know your numerical score, though you typically will not know your Order of Merit position until you are contacted about the next stage. This can take months in a large volume competition.
Can the sample tests on publicjobs.ie replace proper practice?
Official self-assessments can illustrate their stated format, but do not assume they reproduce the current competition. Follow the invitation and familiarisation guide you receive, then choose relevant practice.
