What Is the Casper Test?

The Casper test can feel like the final hurdle before medical school admissions. Since the situational-judgement test does not have one clear-cut answer, the test may often seem daunting for first-time test takers. However, performing well on the Casper test is not about crafting the “perfect” answer for each question, but is instead about showing sampling personal characteristics such as a strong capability to reflect under pressure, and above all demonstrating a high-level empathy and professionalism in approaching each question.

In this article, we will guide you through what the Casper test really is, why achieving a high score is important towards your medical school admissions, and uncover effective preparation methods to strengthen your score.

I. The Role of Casper Test for Medical School

Let’s begin by answering what is the Casper test and why is it important for medical school. The Casper test is more than just another checkbox in the medical school admissions process, it’s your chance to stand out before you even reach the interview stage. As a situational-judgment test, Casper was designed by McMaster University to assess whether you have the personal and professional qualities needed to thrive in healthcare. These are qualities that grades and MCAT scores alone can’t capture. The test scores an applicant’s personal and professional skills by examining communication, critical thinking, problem solving, and reasoning capabilities. But what does all this really mean for you, and how can you turn this opportunity into an advantage? Keep reading as we guide you through effective strategies to schedule your test, prepare with purpose and ace the Casper!

II. The Structure and Evaluation Process of the Casper Test

To excel on the Casper exam, it’s important to first understand its structure and how responses are assessed. Casper is a computer-based assessment that is administered through Acuity Insights. The exam is administered through Acuity Insights and includes 11 scenarios, including both typed and video responses. One of the primary challenges of the Casper exam is its strict time constraints, with the entire test lasting between 65 to 85 minutes. In the video response sections, you’ll be presented with two questions (one at a time), and given just 60 seconds to respond to each. For the typed response sections, there will be two questions within a 3.5 minute timeframe. Familiarity with this test format is key to managing time effectively and delivering thoughtful, concise answers under pressure. To submit Casper scores to your preferred school, simply check off the schools you will be applying to when you sign up for an account! The Casper test costs $85 USD, which includes score delivery to seven programs of your choice. Each additional program you wish to send your score to will incur a fee of $18 USD.

We understand that waiting for your Casper results can feel daunting as many medical schools require a minimum score on this exam. However, it’s important to know that the scoring process is designed with fairness in mind. Each section of your test is evaluated by a different rater to minimize bias. Rest assured, the process is structured to give every applicant a fair opportunity to showcase their strengths.

III. Casper vs. Snapshot vs. Duet: Understanding the Components

Different medical school applications require a variety of assessments, so it’s perfectly normal to be uncertain about how Casper, Snapshot, and Duet differ, especially considering they are all offered on your Acuity Insights account. Below, we will clarify each exam’s format and purpose so you can approach your application with complete confidence.

1) Casper: 
This is a 65-85 minute situational-judgement test that focuses on your ability to approach open-ended questions to evaluate your understanding of medical ethics, empathy, and professionalism under pressure.

2) Snapshot: 
This is a concise 10-15 minute “one-way” video interview in which you respond to 2-3 on-screen prompts to demonstrate your communication skills, motivation for medicine, and personal strengths. This test resembles a quick video chat with an admissions officer, only you lead the dialogue. As of the 2022-2023 cycle, Snapshot is no longer a step in the admissions process of medical schools.

3) Duet: 
This is a value alignment assessment that matches your personal values with the values of the medical school you will be applying to. The exam has no specific time limit but is typically completed in around 10-15 minutes. Think of this as a compatibility assessment that matches your priorities with the programs most suited to your aspirations.

Together, these three components offer a multifaceted view of your candidacy, painting a complete picture of who you are as a future healthcare professional.

IV. Why Is the Casper Test Important?

The importance of the Casper test lies in its growing adoption by healthcare professional schools around the world. As a mandatory component of many application processes, the Casper exam offers admissions committees a more holistic perspective of applicants. The Casper test scores essential soft skills such as problem-solving, ethical reasoning, empathy, and communication which are traits that traditional metrics like GPA and standardized test scores often overlook.
