How to Prepare for CASPer: A Step-by-Step Study Plan
If you're applying to medical school in Australia and CASPer is on your list of requirements, there's a good chance you've heard some version of the following: "You can't really prepare for CASPer. Just be yourself."
It's well-intentioned advice, but it's also incomplete — and for competitive applicants, it can be genuinely harmful.
CASPer (Computer-Based Assessment for Sampling Personal characteristics) is a timed, online situational judgement test that evaluates qualities like empathy, ethical reasoning, professionalism, and communication. You write freely. There are no multiple-choice safety nets. And you have very little time per scenario.
The myth that CASPer is "unpreparable" stems from a misunderstanding of what preparation means. You can't memorise a list of correct answers — because there aren't any. But you absolutely can improve your performance by developing a clear response structure, sharpening your ethical reasoning, practising under timed conditions, and training yourself to write concisely and professionally under pressure. These are learnable skills.
A structured preparation plan gives you a genuine competitive edge — not by teaching you to fake qualities you don't have, but by helping you express the qualities you do have more clearly, quickly, and confidently. This guide provides exactly that: a practical, week-by-week study plan with concrete steps, core skill breakdowns, and everything you need to walk into CASPer prepared.
What Is the CASPer Test?
CASPer is delivered through the Altus Assessments platform and consists of 11 scenarios with 22 questions in total, presented as a mix of video-based and text-based situations. For each scenario, you watch a short video or read a written prompt, then type your responses to 2–3 questions within a strict time limit — typically around 5 minutes per scenario.
There are no multiple choice options. You write in full sentences. Your responses are assessed by trained raters across 9 core competencies including:
- Empathy — recognising and responding to others' emotions
- Ethics — reasoning through moral dilemmas with balance and integrity
- Communication — expressing yourself clearly and professionally
- Professionalism — maintaining appropriate conduct and accountability
- Collaboration, Equity, Problem-Solving, Motivation, and Resilience
What makes CASPer uniquely challenging is the combination of time pressure, ambiguity, and open-ended format. Unlike a structured essay, you're expected to identify the key issues in a scenario, reason through them, and propose a course of action — all in a few minutes of writing. Without preparation, most people either run out of time, write in circles, or default to vague platitudes. With preparation, you can do all three tasks efficiently and well.
How Long Should You Prepare for CASPer?
For most applicants, 2–4 weeks of focused preparation is the recommended window. This is enough time to understand the format, develop a reliable answer framework, practise under timed conditions, and refine your responses without burning out.
That said, your ideal prep timeline depends on several factors:
You may benefit from more time if:
- English is not your first language, and writing quickly and fluently under pressure is challenging
- You type slowly (below ~40 words per minute) — typing speed has a direct impact on how much you can communicate per scenario
- You have limited familiarity with ethical reasoning or situational judgement tests
- You're balancing CASPer prep with GAMSAT or UCAT preparation simultaneously
You may be able to manage with a shorter window if:
- You're a strong, fast writer who is already comfortable with ethics and communication scenarios
- You've recently completed similar preparation (e.g., MMI interview prep, other SJTs)
Balancing CASPer with other exams:If you're sitting GAMSAT in March, aim to begin CASPer preparation in April — after GAMSAT results have been submitted and before GEMSAS application deadlines in May. This avoids preparing for two high-stakes assessments simultaneously and lets you give CASPer the focused attention it requires. For UCAT applicants (typically sitting in July), completing CASPer before UCAT preparation peaks — ideally by May — is the cleanest approach.
Step-by-Step CASPer Study Plan
Week 1: Build Your Foundations
Goal: Understand the test, the competencies, and develop a basic answer structure
The first week is about orientation. Before you start practising responses, you need to understand what you're being assessed on and what good looks like. Jumping into practice questions without this foundation often reinforces bad habits rather than building good ones.
Day 1–2: Learn the format thoroughly
- Read the official Altus Assessments CASPer guide from start to finish
- Understand the number of scenarios, the time limits, the platform interface, and the scoring methodology
- Familiarise yourself with the difference between written and video response scenarios
Day 3–4: Study the 9 competencies
- Read our full CASPer competency guide for detailed breakdowns of each of the 9 qualities assessed
- For each competency, write a one-sentence summary of what it means in practice
- Reflect on situations in your own life where you've demonstrated each quality — this builds authentic material to draw on
Day 5–6: Develop a basic answer structureA reliable structure is the single most impactful thing you can develop in Week 1. A useful starting framework:
- Identify the stakeholders — who is involved, and who is affected?
- Acknowledge perspectives — what might each person be feeling or experiencing?
- Address the core issue — what is the central tension or problem?
- Propose balanced action — what would you actually do, and why?
- Reflect if relevant — what would you want to learn or do differently?
You don't need to hit all five steps in every response, and you shouldn't be mechanical about it. But having this scaffold in your head prevents you from staring at a blank screen when the clock starts.
Day 7: Untimed practice
- Complete 5–10 practice questions without a time limit, focusing purely on structure and content
- Don't worry about length or speed yet — the goal is to get used to thinking through scenarios thoroughly
- Review your responses: did you acknowledge emotions? Did you consider multiple stakeholders? Did you avoid jumping to conclusions?
Week 2: Develop Structure and Speed
Goal: Improve clarity, conciseness, and comfort with timed writing
Week 2 is where preparation starts to feel real. You're moving from understanding the framework to executing it efficiently under pressure.
Week 3: Simulate Real Test Conditions
Goal: Build confidence, consistency, and work on identified weak points
By Week 3, you should have a functioning framework and a reasonable sense of your timing. The goal now is to build the consistency and confidence that comes from repeated realistic practice.
Week 4 (Optional): Final Refinement
Goal: Polish performance and prepare the practical logistics of test day
If you have a fourth week before your CASPer sitting, use it for refinement — not for learning new strategies or cramming new material. Introducing new frameworks at this stage tends to create confusion rather than improvement.
Core CASPer Skills You Need to Master
1. Structured Thinking
The most common failure mode in CASPer is disorganised responses — jumping between ideas, repeating yourself, or writing circularly without arriving anywhere. Structured thinking means following a clear, logical progression: here is the problem, here are the relevant perspectives, here is what I would do, and here is why.
You don't need formal paragraph breaks or headings — CASPer responses are short. But readers should be able to follow your reasoning from sentence to sentence without getting lost.
Practise by: Reading your responses back and asking "Could someone who hadn't seen the scenario understand my reasoning from this response alone?"
2. Empathy and Perspective-Taking
Scenarios almost always involve people in difficult situations. Before you propose any course of action, you need to acknowledge the human dimension — what the people involved are likely feeling, what pressures they're under, what needs they have.
This isn't about being soft or avoiding difficult decisions. It's about demonstrating that you see people as people, not just as variables in a problem to be solved. Markers consistently distinguish between responses that acknowledge emotional reality and responses that skip straight to logistics.
Practise by: Before writing any proposed action, writing one sentence that names the emotional experience of the key person in the scenario.
3. Ethical Reasoning
Most CASPer scenarios involve a tension between competing values — honesty vs. harm minimisation, autonomy vs. duty of care, individual need vs. institutional policy. Strong ethical reasoning means naming these tensions explicitly, considering them from multiple angles, and arriving at a proportionate, justified position rather than an automatic verdict.
The four principles of biomedical ethics — autonomy, beneficence, non-maleficence, and justice — are a useful framework for thinking through healthcare-specific dilemmas.
Practise by: After reading a scenario, writing down the two values in tension before writing your response. This forces you to engage with the ethical dimension rather than defaulting to instinct.
4. Communication
Communication in CASPer operates at two levels: how you describe your proposed actions within the scenario (clear, empathetic, contextually appropriate) and how you write your response itself (professional, concise, structured).
Avoid overly complex language — clarity outperforms sophistication in a timed test. Avoid passive constructions and hedging language that makes your responses feel vague. Write as you would want to speak in a professional setting: warm, direct, and considered.
Practise by: Reading your responses aloud. If something sounds clunky, stilted, or overly formal when spoken, rewrite it.
The CASPer Answer Framework
This framework is a reliable scaffold for approaching most CASPer scenarios. Adapt it to the specific question — don't apply it mechanically — but use it as a mental checklist to ensure you're covering the key dimensions.
1. Identify the stakeholdersWho is in this scenario? Who else might be affected by what happens next — patients, families, colleagues, institutions?
2. Acknowledge perspectivesBefore acting, demonstrate that you understand how the situation feels for the key people involved. What might they be experiencing? What do they need?
3. Address the core issue with balanced reasoningName the central tension. What competing values or interests are at stake? What are the realistic options for responding?
4. Propose practical, proportionate actionWhat would you actually do? Be specific. Who would you speak to, and how? What outcome are you trying to achieve? Make sure your proposed action is realistic given the context — not an idealised response that ignores practical constraints.
5. Reflect if necessaryIn scenarios involving personal challenge, mistakes, or ongoing difficulty, a brief reflective close adds depth. What would you want to learn from this? How would you support yourself or others going forward?
Common CASPer Mistakes to Avoid
Leaving preparation too late
CASPer rewards practiced fluency. Starting the week before your test, when you're also managing GAMSAT/UCAT stress and application paperwork, is not a recipe for a strong performance. Two to four weeks of preparation makes a genuine difference.
Writing generic or vague answers
Responses full of filler — "I would try to understand the situation," "I would do my best to help," "communication is very important" — score poorly because they say nothing specific. Be concrete: who would you speak to, what would you say, what outcome are you trying to achieve?
Ignoring time pressure in practice
Practising without a timer feels safer but doesn't prepare you for the experience of actually running out of time mid-response. Timed practice is uncomfortable at first — that's exactly why it's necessary.
Being overly extreme or one-sided
Immediate escalation, harsh judgment of others, or absolute certainty in complex situations reads as clinically immature. Real situations are messy. Responses that acknowledge nuance and consider multiple options before acting consistently score better.
Forgetting professionalism
In scenarios involving peer misconduct, conflict, or personal frustration, it's easy to write responses that are subtly unprofessional — judgmental, gossipy, or disproportionately punitive. Step back before writing and ask: "Would I be comfortable if a supervising clinician read this response?"
Moralising instead of reasoning
Spending your response explaining why something is wrong rather than working through what to do about it is a common trap. Markers aren't looking for moral authority — they're looking for practical, balanced judgment.
CASPer Test Day Tips
Set up your environment in advance
CASPer is delivered online, which means your test-day environment is your responsibility. Choose a quiet, private space where you won't be interrupted. Remove distractions. Ensure adequate lighting if your test includes video responses.
Test your technology beforehand
Run a full technical check at least 24 hours before your sitting: internet speed and stability, webcam, microphone, browser compatibility, and the Altus Assessments platform itself. The Altus Assessments technical requirements page lists exactly what you need. Technical issues on test day are stressful and sometimes unrecoverable — eliminate this risk in advance.
Manage your time strictly
You will not be able to extend your time if you run out mid-response. Practise finishing your responses within the allocated time, even if that means a shorter but complete answer rather than a longer but unfinished one. A structured 150-word response scores better than a rambling 300-word response that never arrives at a conclusion.
Stay calm and composed
If a scenario stumps you, take a breath. Jot down the key stakeholders mentally, acknowledge the emotional dimension in your first sentence, and work through your framework. Some uncertainty in your response — "I would want to find out more before acting" — is completely acceptable and often demonstrates good judgment. Panic, on the other hand, is clearly visible in the writing.
Don't dwell on previous scenarios
Once a scenario is over, it's over. You cannot go back. Ruminating on a response you're unhappy with wastes the limited time you have for the next one. Move forward with a clean slate.
