The Casper test is scored by human raters. Each of the 11 scenarios is evaluated by a different person, so 11 independent raters provide 11 separate scores. Responses are generally evaluated on a numerical scale (from 1 to 9).
The testing system then aggregates and standardizes those scores to produce your final result, which is reported as a quartile (1st to 4th) relative to other applicants.
Your score reflects how well you demonstrate key professional and interpersonal skills compared to other test-takers.
Casper uses multiple raters to ensure fairness and consistency:
After all responses are scored, your scores are averaged across raters. Then they are standardized. That means your performance is compared to others who took the test on the same day.
This process reduces bias and ensures that one weak response does not disproportionately affect your final result.
Raters don't have an "answer key" to score each scenario. Instead, they use a standardized rubric to evaluate how well you demonstrate 10 core competencies:
Each response is scored on a 1-9 scale, where 1 is poor and 9 is excellent.
Raters focus on:
They are instructed to ignore spelling, grammar, and typing speed. Strong answers show thoughtful reasoning, not perfect writing.
Responses that suggest unsafe, unethical, or unprofessional behavior are flagged and can significantly lower your score.
Casper scores are reported differently to applicants and to medical schools. You do not see your exact Casper score. Instead, you receive a quartile ranking that shows how you performed relative to other test-takers on your test date.
Your result will fall into one of four groups:
This quartile system gives you a broad performance range, not a precise score. You will not see your raw score, percentile, or how close you were to another quartile.
No, medical schools do not see your quartile ranking. They receive a z-score, which is a more precise measure of your performance.
A z-score tells admissions committees how many standard deviations your score is above or below the mean of your test cohort. In simple terms, it answers the following:
In practical terms:
The further from 0, the stronger or weaker your performance.
For example, let’s say two applicants both received a 4th quartile result.
Both are in the top quartile, but Applicant B performed significantly stronger.
Unlike quartiles, which group applicants into broad ranges, z-scores give schools a precise measure. This lets them:
It’s also important to understand that Casper scores are standardized within each test cohort (your test date). Schools interpret your performance relative to others who took the test at the same time, not across all applicants globally.
You typically receive your Casper score about four weeks after your test date.
Here’s how the timeline works:
This delay happens because multiple human raters manually score Casper. They then average and standardize the scores before releasing results.
Keep in mind that schools receive your scores before you do, so your application can continue moving forward even if you have not yet seen your results.
You score well on the Casper test by clearly explaining your reasoning, considering multiple perspectives, and demonstrating professionalism.
Strong responses:
Casper rewards how you think, not just what you decide. There is no single “correct” answer because multiple responses can be appropriate depending on your reasoning.
Your Casper score is somewhat important for schools that require or recommend it, but it is only one part of your application. Most programs use Casper as a supplemental screening tool to assess professionalism and interpersonal skills. Schools typically consider it alongside your GPA, test scores, essays, and experiences.
Few med schools use strict cutoffs, so a lower score does not automatically disqualify you.
You can find your Casper quartile score in your Acuity Insights account about four weeks after your test date. You will see a quartile ranking (1st to 4th) that shows how you performed relative to other test-takers. You will not see your raw score or exact percentile.
A good Casper score is typically in the 3rd or 4th quartile.
Programs interpret Casper scores within the context of your full application.
No, you cannot technically fail the Casper test. Casper does not use a pass-or-fail system. Instead, you receive a quartile ranking that shows how you performed relative to other test-takers.
The lowest possible result is the 1st quartile, which means you scored lower than most applicants in your cohort. While this may weaken your application, it does not automatically disqualify you.
Admissions committees review Casper as part of a holistic application, so they consider your score alongside your GPA, test scores, essays, and experiences.
You cannot retake Casper within the same admissions cycle. You are allowed to take Casper once per cycle. Your score is distributed to all selected programs. If you apply again in a future cycle, you have to take the test again.
You can improve your Casper performance by practicing structured responses and focusing on ethical reasoning.
