How is the CASPer Test Scored: The Rater System
The Pool of Trained, Anonymous Raters
The CASPer test scoring process relies on a diverse group of human raters rather than automated algorithms. These raters are typically sourced from the general population but undergo rigorous training to ensure they can identify specific behavioral indicators. The diversity of the rater pool is intentional; it aims to reflect the demographic variety of the patient populations that future healthcare professionals will serve. Raters are trained to ignore superficial factors like writing speed or minor typos, focusing instead on the underlying logic of the response. This human element is critical because situational judgment requires an appreciation for nuance that artificial intelligence cannot yet reliably replicate. Each rater is assigned to a specific scenario, meaning they spend their entire shift grading only one of the 14 sections of the test. This specialization allows them to become experts in the specific ethical dilemmas posed by that scenario, enhancing the reliability of the scores they provide.
Blinded Grading: One Rater Per Response
A cornerstone of the CASPer methodology is the blinded grading system. When you sit for the exam, your total score is not determined by a single individual. Instead, each of your 14 responses is sent to a different, independent rater. This means that if you perform poorly on the first scenario, the rater for the second scenario has no knowledge of that struggle. This "one rater per response" rule eliminates the halo effect—a psychological bias where a rater’s overall impression of a candidate is influenced by a single positive or negative trait. By distributing your responses across 14 different individuals, the system ensures that your final score is an aggregate of multiple independent perspectives. This structural design protects candidates from the subjective bias of any one rater, as an outlier score in one section is statistically diluted by the scores in the remaining thirteen sections.
Calibration and Quality Assurance Processes
To maintain high inter-rater reliability, the test administrators employ sophisticated calibration techniques. Before a rater begins scoring live responses, they must pass a series of benchmark tests using pre-graded responses. If their scores deviate significantly from the established gold standard, they are required to undergo further training. Furthermore, quality assurance continues throughout the scoring window. Raters are periodically presented with "check" responses—scenarios that have already been scored by expert panels. If a rater’s performance drifts from the expected rubric, their previous scores may be flagged for review. This statistical monitoring ensures that the CASPer raters and grading standards remain consistent across different days and time zones. This level of oversight is necessary because the exam results are used for high-stakes admissions decisions, requiring a degree of precision that matches traditional GPA or MCAT metrics.
Decoding the CASPer Scoring Rubric
Core Competencies Measured (Empathy, Ethics, etc.)
The CASPer scoring rubric explained centers on ten core competencies, including empathy, ethics, communication, and problem-solving. Raters do not look for a specific "right" answer but rather for evidence that the candidate has considered the multiple perspectives involved in a conflict. For instance, in a scenario involving a colleague’s unprofessional behavior, a high-scoring response would demonstrate professionalism by addressing the issue directly while also showing empathy for the underlying causes of that colleague's stress. The rubric rewards candidates who can articulate the ethical tensions of a situation—such as the conflict between autonomy and beneficence in a clinical setting. By identifying these specific pillars, the rater can assign a numerical value (typically on a 1–9 scale) based on how many of these professional traits the candidate naturally integrated into their response.
How Raters Evaluate Thought Process Over a 'Correct' Answer
One of the most common misconceptions is that there is a "correct" resolution to a CASPer scenario. In reality, the thought process is the primary metric of evaluation. Raters are instructed to look for "showing your work." This involves identifying the stakeholders, acknowledging the complexity of the situation, and proposing a solution that minimizes harm. A candidate who reaches a conclusion without explaining their reasoning will score lower than a candidate who considers several options before settling on a course of action. This approach mirrors clinical practice, where the rationale behind a medical decision is often as important as the decision itself. Raters use a global assessment approach, meaning they look at the response as a whole to determine if the candidate demonstrated the maturity and social intelligence required for their chosen profession.
Common Pitfalls That Lower Scores
Low scores on the CASPer are often the result of "red flag" behaviors or shallow reasoning. One major pitfall is taking a judgmental or aggressive stance. If a candidate uses inflammatory language or fails to consider why a person might be acting in a certain way, they fail the empathy and collaboration criteria. Another common error is the "missing the point" fallacy, where a candidate focuses on a minor detail of the prompt while ignoring the central ethical dilemma. Additionally, providing a response that is too brief to demonstrate depth—often referred to as a "thin" response—prevents the rater from seeing the candidate's full analytical capability. To avoid these, candidates must use cause-effect reasoning, explaining not just what they would do, but why that action is the most ethical path forward given the constraints of the scenario.
From Raw Scores to Quartile Rankings
How Your Total Score is Calculated
The CASPer score calculation begins with the raw scores assigned by the 14 individual raters. Each rater provides a score on a Likert-style scale, usually from 1 (unsatisfactory) to 9 (superlative). Because different scenarios may have different levels of difficulty, the raw scores are standardized. This means your score for a particularly difficult scenario is adjusted relative to how all other candidates performed on that same scenario. These standardized scores are then summed to create a total composite score. It is important to note that the video response section and the typed response section are scored separately but follow the same underlying logic. The final composite score represents a holistic view of your non-cognitive profile, balanced across multiple prompts and varied rater perspectives.
The Percentile Ranking and Quartile Conversion
Once the raw scores are standardized and totaled, they are converted into a CASPer quartile scoring system. This is a relative ranking, meaning your score is entirely dependent on where you sit in the distribution of all test-takers for that specific test type and cycle. The quartiles divide the test-taking population into four equal groups: the top 25% (4th quartile), the 51st–75th percentile (3rd quartile), the 26th–50th percentile (2nd quartile), and the bottom 25% (1st quartile). This normative scoring method is used because it provides admissions committees with a clear picture of how a candidate compares to the current applicant pool. Unlike a percentage score (e.g., scoring an 85%), a quartile tells the program exactly how competitive you are relative to your peers, which is more useful in a competitive admissions landscape.
Understanding What Your Quartile Placement Means
When candidates ask what do CASPer scores mean, they are often looking for a pass/fail threshold. However, the quartile placement simply indicates your relative strength in social intelligence and ethical reasoning. A 4th-quartile score suggests that you consistently demonstrated high levels of empathy, professional boundaries, and complex problem-solving across nearly all scenarios. A 1st-quartile score does not necessarily mean you are an "unethical" person; rather, it indicates that your responses were less detailed, less nuanced, or less aligned with the specific professional competencies the test measures compared to your peers. Programs use these quartiles as a "screen-in" or "screen-out" tool. Some schools may have a hard cutoff (e.g., only interviewing 3rd and 4th quartile applicants), while others use the score as a tie-breaker between two candidates with similar academic credentials.
Score Reporting: What You and Programs See
The Confirmation of Completion vs. The Actual Score
After completing the exam, you will not receive a numerical breakdown of your performance. Instead, you receive a confirmation that your test has been processed. Approximately one month after the test date, you will be notified of your quartile ranking. This is the only information you receive regarding your performance. You do not get to see the individual scores for each scenario, nor do you receive feedback on which competencies you excelled in or struggled with. This lack of granular feedback is a common point of frustration for candidates, but it is a deliberate choice by the test providers to maintain the security of the test bank and prevent candidates from "gaming" the system in future attempts. The focus remains on your relative standing rather than a specific point value.
How Programs Receive Your Quartile Results
While you only see your quartile, the programs you apply to receive a more detailed report. Admissions committees are provided with your specific percentile rank within the quartile, which allows them to see exactly where you fall on the bell curve. For example, two students in the 3rd quartile might be viewed differently if one is at the 52nd percentile and the other is at the 74th percentile. Programs also receive the scores for the video and typed sections separately, as some institutions may weigh the video response more heavily to assess verbal communication skills. This data is integrated into the school’s internal admissions software, often alongside the applicant’s GPA and standardized test scores, to create a comprehensive "holistic" score for the file review process.
The Validity Period of Your CASPer Score
It is essential to understand that a CASPer score is only valid for a single application cycle. If you are a re-applicant, you must retake the exam, even if you previously achieved a 4th-quartile result. This is because the test is scored relative to the current year’s applicant pool. Because the "strength" of the pool can change from year to year, a score from 2023 cannot be accurately compared to the scores of 2024. Furthermore, scores are specific to the "test type." For instance, if you apply to both Medical (MD) and Physician Assistant (PA) programs, you may be required to take different versions of the test, and the scores are not interchangeable. Keeping track of the validity period ensures that you do not inadvertently miss a deadline by relying on an expired result.
Factors That Do NOT Influence Your Score
Spelling and Grammar (Within Reason)
One of the most significant stressors for candidates is the pressure to type quickly without making mistakes. However, the official grading policy states that spelling and grammar do not negatively impact your score. Raters are specifically trained to look past "typos" and "fragmented sentences" as long as the core message remains intelligible. The rationale is that CASPer is not a test of English proficiency or typing speed; it is an assessment of ethical decision-making. As long as your reasoning is clear, you can use abbreviations or bullet points to save time. However, if your grammar is so poor that it obscures the meaning of your response, the rater will be unable to award points for the competencies you are trying to demonstrate. Therefore, "within reason" means that clarity is paramount, but perfection is not required.
Personal Opinions vs. Professional Reasoning
Candidates often worry that they will be penalized for having the "wrong" opinion on a controversial topic. CASPer raters are instructed to remain neutral regarding a candidate’s personal or political beliefs. What they are scoring is the professional reasoning behind those beliefs. For example, if a scenario asks about a controversial medical procedure, you will not be docked points for being "pro" or "con." Instead, you are evaluated on your ability to recognize the ethical principles at play, such as patient autonomy or social justice. A high-scoring response demonstrates that the candidate can set aside personal bias to follow professional guidelines or legal requirements. The rubric focuses on your ability to function within a professional framework, regardless of your private views.
The 'Perfect' or 'Expected' Answer Myth
There is a persistent myth that there is a "hidden" perfect answer that will automatically grant a 9/9 score. This is false. Because the test uses a global assessment model, raters are looking for the quality of the synthesis. Two candidates could take completely different approaches to the same problem and both receive 4th-quartile scores. One might focus on the interpersonal dynamics and emotional intelligence, while another might focus on the systemic implications and policy requirements. Both are valid as long as they show depth, maturity, and a multi-perspective analysis. Attempting to guess the "expected" answer often leads to generic, "robotic" responses that lack the depth required for a top-tier ranking. Authenticity, backed by a structured ethical framework, is the most reliable path to success in the CASPer scoring system.
