The SJT is worth 40% of your final ranking in the ICGP's GP training selection process. That makes it the biggest single lever most candidates control directly, since the SBCA depends on live performance and the CPST caps out at 10%. Most people who prepare for the Irish GP exam start in the wrong place, reading ethics theory instead of practising scenarios, or treating it like a fact-based test with a right answer to memorise. It's actually a judgement test with a consistent internal logic, one that's learnable with the right kind of practice.
This guide assumes you already know roughly what the SJT is (45 scenarios, ranking and multiple-choice items, two question formats), covered in the full format and scoring guide if you need that first. What follows is how to actually prepare: a diagnostic to find your weak domains, what to read alongside practice, three study timelines, the techniques that move your score, what a real practice session looks like, and the mistakes that quietly cost candidates marks every cycle.
Key takeaways
- The SJT rewards a learnable, consistent judgement logic, not memorised facts. Practice beats theory from day one.
- A short diagnostic before you pick a timeline shows you which of the six competency domains to prioritise, so no week of practice is wasted.
- Read the explanation on every scenario, including the ones you get right. That's where the reasoning pattern the ICGP is looking for actually shows up.
- Answer as the textbook-ideal doctor, not the doctor you see get things done on a busy ward. Real hospital shortcuts often score low on the SJT.
- GP Journey's adaptive study planner builds your schedule around your weak domains and your actual available hours, whatever your timeline.
How much you study matters less than how you review. A candidate who works through 150 scenarios and reads every explanation, including on the ones they got right, will consistently outscore someone who rushes 500 and only checks whether they were correct. Build your plan around review quality first, volume second.
How Much Time Do You Actually Need?
Most candidates preparing for the Irish GP exam get through it successfully in one to three months of structured practice. That range is wide on purpose. The right length depends on your starting comfort with ethical reasoning, how much protected study time you can realistically carve out around clinical work, and how close you already are to test day.
Below are three real starting points. Find the one that matches your calendar and use that timeline rather than trying to force a twelve-week plan into six weeks. For the 2027 intake, the SJT and CPST are sat across Wednesday 4 and Thursday 5 November 2026, per the ICGP's own recruitment timeline, so count backward from that fixed window rather than an assumed one.
Start With a Diagnostic
Before you commit to a timeline, spend 30–45 minutes finding out where you actually stand. Attempt 10–15 SJT scenarios untimed, with no research or second-guessing, then mark each miss against the competency domain it tested: Professional Values and Behaviours, Communication and Consultation Skills, Clinical Knowledge and Expertise, Managing Medical Complexity, Working with Colleagues and in Teams, or Community Orientation.
This changes what your study plan actually does. Instead of spreading practice evenly across all six domains, you spend the bulk of your weeks on the one or two that are genuinely costing you marks. That's the difference between a twelve-week plan that covers everything shallowly and one that closes your specific gaps.
350+ SJT scenarios. Real ranking format. Full explanations.
Now that you know your weak domains, GP Journey's scenario bank mirrors the real ranking and best-3-of-8 formats, with a full expert explanation for every option, not just the correct one, so you can drill exactly where the diagnostic showed you're losing marks.
HSE TSS eligible · most Irish hospitals cover the full costWhat to Read Alongside Practice
SJT preparation is mostly practice, not reading, but one piece of background is worth having before you start: the professional-standard framework the scenarios are built on. There are two ways to get it, and you only need one.
The source document is the Irish Medical Council's Guide to Professional Conduct and Ethics for Registered Medical Practitioners (9th edition, effective January 2024). Reading it once gives you the vocabulary and reasoning baseline that every SJT scenario assumes.
The faster route is GP Journey's SJT Knowledge Base, which breaks down each of the six competency domains, how it's actually tested, and works through real scenario examples showing what separates a high-ranking response from a low-ranking one, domain by domain. It's the same underlying standard as the IMC guide, translated directly into SJT terms.
Three Study Plans, by Timeline
Each plan below follows the same underlying shape: understand the domains, build volume, tighten under time pressure, and taper before test day. Each one is just compressed to fit however many weeks you actually have.
| Timeline | Weeks 1–2 | Middle stretch | Final week |
|---|---|---|---|
| 12 weeks out | Read the six competency domains; write one real example from your own practice for each | 15–35 scenarios/week, rising volume, full explanation review every time, timed practice from week 8 | Light review only: 10–15 scenarios/day, no new concepts |
| 6 weeks out | Skim the domains once; go straight to scenario practice, 20–25/week | 25–30 scenarios/week, timed blocks from week 3, focus review time on your weakest one or two domains | Two full timed 45-question sets, review both fully, then stop |
| 2–3 weeks out | Skip domain theory. Go directly to daily scenario practice, 10–15/day | One full timed set every 2–3 days, review every explanation the same day | One final timed set, light review, protect sleep over extra volume |
A shorter runway means less theory, not less review. The review step is what actually builds the judgement.
Building any of these three plans by hand is optional. GP Journey's adaptive Study Planner generates the week-by-week schedule for you. Tell it your exam date and how many hours you have free each week, and it slots scenario volume, timed blocks and taper weeks around that automatically, then adjusts as your weak domains shift.
The Techniques That Actually Move Your Score
Volume alone plateaus quickly. These are the specific habits that keep scores climbing past that plateau.
Five habits worth building
- Anchor from both ends. On ranking items, identify your clear best option and your clear worst option first. Those two are usually obvious. The middle three are where the real judgement gets tested, and they get easier to place once the ends are fixed.
- Read every explanation, including on questions you got right. A correct ranking for the wrong reason is a warning sign, not a win. The explanation is where you actually see why one option outranks another, which is the whole skill the SJT is testing.
- Keep a short error log. One line per scenario you got meaningfully wrong: what you picked, what the correct ranking was, and the one-sentence reason why. Re-read it weekly. Patterns show up fast.
- Practise under real time pressure before test day, not just on it. Forty-five scenarios in 90 minutes is two minutes each. Timed practice sets are what make that pace feel normal instead of threatening.
- Trust your first instinct on review. Your first read of a scenario is usually more reliable than a second-guessed revision. Change an answer only when you spot a genuine misread, not because of doubt alone.
What an Actual Practice Session Looks Like
"Do more scenarios" isn't specific enough to act on. Here's what one good rep actually looks like, step by step:
One practice rep, six steps
- Read the scenario cold. No skimming ahead to the options. Form your own read of the situation before anything else influences it.
- Form your own instinct before looking at the options. What would you actually prioritise here, in your own words, before the five or eight choices anchor your thinking.
- Anchor from both ends. Pick your clear best option and your clear worst option first, then work the middle three.
- Submit, then read every explanation. Including the options you didn't rank at either end. That's usually where the specific competency domain being tested becomes obvious.
- Log the gap. One line in your error log if you got it wrong, or ranked correctly for the wrong reason: what you picked, what was right, why.
- Move on. Don't dwell on one scenario past its explanation. Dwelling is theory, not practice.
A worked example of step three: a scenario where a junior colleague has missed a critical abnormal result. The clear best option is usually escalating through the proper clinical governance channel. The clear worst is ignoring it or handling it informally to avoid an awkward conversation. The middle three (a direct one-to-one conversation with the colleague, an anonymous incident report, or raising it at the next team meeting) are where the real judgement gets tested. Once you've fixed the two ends, they're usually easier to rank by comparison alone.
Answer as the textbook-ideal doctor, not the doctor you see getting things done on a busy ward. The SJT scores against the ICGP's professional standard, not against how things often actually happen in practice. If your instinct is "this is how we'd handle it in real life" rather than "this is what a doctor should do," that instinct is often exactly what costs marks. Normalised shortcuts, deferring up the hierarchy to avoid friction, or sorting things out informally can feel practical on the ward, and can still rank low on the SJT, because the test measures the idealised professional response, not the pragmatic one. Real clinical experience is an asset for the CPST. On the SJT, it can occasionally work against you if you let it override the standard the scenarios are actually written to.
Mistakes That Quietly Cost Marks
None of these are dramatic. They're small, easy-to-miss habits that add up over 45 scenarios.
What to avoid
- ×Studying clinical knowledge for the SJT. That preparation belongs to the CPST. The SJT tests judgement and professional values, not medical facts. Time spent on textbooks here is time not spent where it counts.
- ×Skipping explanations on questions you got right. Covered above, but it's the single most common gap in self-directed prep.
- ×Cramming in the final 48 hours. New scenario volume that late tends to introduce doubt rather than confidence. Light review only, and protect sleep.
- ×Ignoring your weakest competency domain. It's tempting to keep practising what you're already good at because it feels productive. The marks you're losing are concentrated in the domain you're avoiding.
- ×Never practising under a clock. Untimed practice teaches you to reason well. It doesn't teach you to reason well in two minutes. Both skills are required on test day. GP Journey's Mock Exam mode replicates the real 45-scenario, 90-minute format exactly, so you build that pacing before test day instead of discovering it live.
How GP Journey Helps You Prepare
Every technique above depends on having enough well-explained scenarios to practise with, a way to see which domain is actually costing you marks, and the Knowledge Base to make sense of both. That's the specific gap GP Journey closes.
The bank runs to 350+ SJT scenarios, each with a full expert explanation for every option, not just the correct one, so you can see why the top-ranked response is right and why each of the others is comparatively weaker, question by question. It's the "anchor from both ends" technique built directly into the review.
Every scenario also breaks down the ranking logic within the question itself: not just a final score, but the reasoning that separates a 1 from a 2 and a 4 from a 5, which is exactly where most of the real judgement (and most of the marks) lives.
Personalised analytics track your performance by competency domain automatically, so instead of guessing which domain to prioritise, you can see it directly and put your remaining study time there. The adaptive study planner then builds your schedule around two things at once: your weak domains, and how many hours you actually have available each week, whether that's the twelve-week plan above or the two-week crunch. SJT, CPST, and interview prep all sit on one synced timeline, and it's HSE TSS eligible, so cost isn't a barrier for most candidates either.
You have the plan. Now build the reps.
Start with real ICGP-style scenarios, full expert explanations, and a study planner that adapts to your weak domains and your actual hours.

Frequently asked questions
Most candidates prepare successfully in one to three months of structured practice. Twelve weeks gives the most comfortable runway, but a focused six-week plan is enough if you study consistently. What matters more than total weeks is consistent practice with full review of every explanation, not just the number of weeks on the calendar.
Volume matters less than review quality. A candidate who works through 150 scenarios and reads every explanation, including on questions they got right, will outperform someone who rushes through 500 and only checks whether they were correct. As a rough guide, 15–20 scenarios a week with full review is a sustainable pace for most working doctors.
Start with the SJT. It carries 40% of your final ranking against the CPST's 10%, and the judgement-based thinking it rewards takes longer to build than clinical knowledge revision. Most candidates run both in parallel eventually, but SJT should get the earlier and larger share of study time.
It is possible but tighter. A compressed plan should drop broad domain study and go straight to daily scenario practice with full explanation review, prioritising the competency domains you score weakest on first. It is not the ideal path, but consistent daily practice in a short window still beats no structured preparation at all.
No. The SJT does not test clinical knowledge; it tests professional judgement, ethics, and behaviour in realistic workplace scenarios. Opening a clinical textbook is time better spent on the CPST. For the SJT, the right preparation is scenario practice and understanding the ICGP's competency domains, not medical revision.
Treating it like a fact-based test with one right answer to memorise, rather than a judgement test with a consistent underlying logic to internalise. The second most common mistake is skipping the explanation on questions they already got right, which is exactly where that underlying logic starts to become visible.
Either works, and you don't need both. The Irish Medical Council's Guide to Professional Conduct and Ethics is the source document the SJT's professional standard is built on. GP Journey's SJT Knowledge Base covers the same standard, but breaks it down domain by domain with worked scenario examples showing what a high-ranking answer looks like versus a low-ranking one. Reading is background; scenario practice with full explanations is what actually moves your score.
That gap is common, and it's usually not a knowledge problem. The SJT scores against the ICGP's idealised professional standard, not against how things are often handled in a busy, real-world hospital. If your instinct reflects "how we actually do it on the ward" rather than "what a doctor should do," practising more scenarios and reading every explanation is what closes that gap, not more clinical experience.
Review your error log rather than trying to learn anything new. A short, manageable amount of practice is fine; a large new batch of scenarios the day before tends to introduce doubt rather than confidence. Confirm your webcam, ID, and quiet room are sorted, then prioritise sleep over one more study session. You want to arrive clear-headed, not exhausted from last-minute revision.
Before Test Day: A Quick Checklist
Ten questions worth asking yourself
- Have I completed an initial diagnostic?
- Do I know which competency domains are weakest?
- Have I practised realistic SJT scenarios, not just read about the format?
- Do I read explanations even when I get the answer right?
- Do I keep an error log, or something that tracks the same patterns automatically?
- Have I practised ranking questions with the anchor-from-both-ends technique?
- Have I completed timed practice at the real 2-minutes-per-scenario pace?
- Can I tell the difference between professional judgement and an everyday clinical shortcut?
- Have I actually reviewed my recurring mistakes, not just logged them?
- Is my final week focused on review rather than cramming new material?
Yes to most of these means your preparation is already structured around what the SJT actually rewards.
