CASPer Test Scoring Explained: How Your Responses Are Rated
Understanding CASPer scoring is crucial for medical school applicants. Unlike traditional tests with numerical scores, CASPer uses a quartile ranking system that compares your performance to other test-takers. Here's everything you need to know about achieving a competitive score.
🎯 Quick Scoring Overview
Quartile System
- 4th Quartile: Top 25% of test-takers
- 3rd Quartile: 50th-75th percentile
- 2nd Quartile: 25th-50th percentile
- 1st Quartile: Bottom 25%
How to interpret the result
- Relative: Quartiles compare performance in broad bands
- Program-specific: Check the current admissions policy
- No universal cutoff: Do not assume a minimum for all schools
- First quartile: A lower band, not a pass/fail verdict
How CASPer Scoring Actually Works
Received a lower band? Read what a first-quartile CASPer result means before drawing conclusions about an application or the cause of your score.
The mechanics below explain how responses become a quartile. For a closer look at the judgment signals behind those ratings, read what CASPer actually scores. And for what a top result specifically means, see what a 4th-quartile CASPer score means.
The Evaluation Process
Step 1: Human Raters
Trained, accredited human raters review anonymized responses and score the judgment shown in each answer rather than looking for a single “correct” response. See who grades CASPer for how raters are trained and checked.
Step 2: Independent Question Scores
Each question is scored independently. One rater sees both questions attached to a scenario, while different scenarios are distributed across different raters. The averaged ratings are then standardized; the CASPer z-score guide explains how.
Step 3: Scenario-Specific Judgment
Acuity does not publish a universal ten-box checklist for applicants. Raters use scenario-specific criteria and focus on the substance, thought process, judgment, and communication in your response.
Step 4: Quartile Ranking
Your final score is compared to all other test-takers in your testing cycle and converted to a quartile ranking.
Understanding Quartile Rankings
Detailed Quartile Breakdown
4th Quartile (75th-100th percentile)
EXCELLENT- Top 25% of all test-takers
- A higher relative result for that assessment
- Does not guarantee an admissions offer
- Does not reveal an exact percentile within the band
- Does not provide a separate rating for each competency
3rd Quartile (50th-75th percentile)
GOOD- Above-average performance
- Admissions use depends on the program
- Not a universal admission threshold
- Not a question-by-question report
- Check the applicable cycle and program policy
2nd Quartile (25th-50th percentile)
AVERAGE- A lower-middle relative band
- Not a percentage of questions answered correctly
- No diagnosis of a particular response weakness
- Not an automatic admissions outcome
- Interpret alongside the program's stated policy
1st Quartile (0-25th percentile)
LOWER BAND- Below-average performance
- May impact medical school competitiveness
- A low result does not create a same-cycle retake option
- Review fresh practice if you have a future required sitting
- Do not infer a specific personal weakness from the band
📊 Score Distribution Reality
Understanding the actual distribution helps set realistic expectations:
4th Quartile
3rd Quartile
2nd Quartile
1st Quartile
Key insight: Students using CasperCoach's preparation system achieve 3rd-4th quartile at rates significantly higher than the general population.
What Makes a 4th Quartile Response?
Characteristics of Top-Scoring Responses
Content Quality
- Demonstrates multiple competencies simultaneously
- Shows sophisticated ethical reasoning
- Considers multiple stakeholder perspectives
- Provides specific, actionable solutions
- Acknowledges complexity and nuance
Communication Style
- Clear, professional language
- Empathetic and non-judgmental tone
- Well-organized thought progression
- Appropriate length and detail
- Error-free grammar and spelling
❌ What Hurts Your Score
Judgmental Responses
Harsh criticism of others, moral superiority, or dismissive attitudes toward different perspectives.
Oversimplified Solutions
One-size-fits-all answers that ignore complexity or fail to consider multiple stakeholders.
Poor Communication
Unclear writing, excessive errors, inappropriate tone, or responses that are too brief or too lengthy.
Avoidance of Difficult Issues
Failing to address the core ethical dilemma or providing vague, non-committal responses.
How Medical Schools Use CASPer Scores
Integration with Other Application Components
Holistic Review Process
CASPer scores are considered alongside GPA, MCAT, experiences, and personal statements to provide a complete picture of applicant readiness.
- Academic metrics: GPA and MCAT show cognitive ability
- CASPer: Demonstrates professional competencies and ethical reasoning
- Experiences: Show commitment and exposure to healthcare
- Essays: Reveal motivation and communication skills
🏥 School-Specific Considerations
High CASPer Weight Schools
- McMaster University (Canada)
- University of Ottawa (Canada)
- New York Medical College
- Virginia Tech Carilion
- Many DO programs
Moderate CASPer Weight
- Most Canadian medical schools
- Several US MD programs
- Many nursing programs
- Some PA programs
- Veterinary schools
Research tip: Check each school's specific CASPer requirements and weighting on CasperCoach's school database.

Frequently Asked Questions
Q: Can I retake CASPer to improve my score?
A: CASPer can only be taken once per admissions cycle. However, you can take it again in subsequent years if you're reapplying.
Q: How much can preparation improve my score?
A: Students typically improve by 1-2 quartiles with proper preparation. The biggest improvements come from understanding competencies and practicing response frameworks.
Q: Do medical schools see my individual responses?
A: No, schools only receive your quartile ranking and competency breakdown. They do not see your actual written responses.
Q: Is 3rd quartile good enough for medical school?
A: 3rd quartile is competitive for most programs, but 4th quartile significantly strengthens your application, especially for competitive schools.
