What Is the CASPer Test for Medical School — Explained (with Test Format Details)
If you’re applying to medical school, you’re almost certainly going to encounter the CASPer test — a behavioral assessment used 30+ MD and DO programs to evaluate applicants beyond grades and test scores (basically, it’s to make sure you’re not a sociopath). In this article, I’ll explain what CASPer is, why medical schools require it, and precisely what the test format looks like, so you know what to expect on test day.
What Is the CASPer Test?
CASPer stands for Computer-Based Assessment for Sampling Personal Characteristics. It’s an online situational judgment test (SJT) that assesses the personal and interpersonal qualities medical schools value in future physicians — including empathy, ethics, communication, professionalism, and problem-solving. Unlike the MCAT, CASPer doesn’t test academic knowledge or science facts. Instead, it gives schools insight into how you respond to real-world scenarios and handle challenging situations thoughtfully and ethically.
Why Medical Schools Use CASPer
Admissions committees want to build classes of students who demonstrate essential soft skills (compassion, fairness, resilience, and communication) that predict success in clinical settings. CASPer gives schools a way to measure these qualities early in the admissions process. How to use by medical schools will vary. CASPer is sometimes used before interviews to help schools screen applicants, whereas other schools are still trialing it as an experimental method of stratifying applicants' competitiveness.
CASPer Test Format — What to Expect
The CASPer test is timed and interactive, with scenarios that may be video-based or text-based. It typically takes about 65–85 minutes to complete, including optional short breaks. Take Casper +1
Here’s a breakdown of the main components:
1. Video Response Section
You'll see video or written scenarios. After each scenario, you’ll be presented with two questions. You’ll have 1 minute to record your spoken response to each question using your webcam. This section tests your ability to think and communicate under time pressure.
2. Typed Response Section
This part contains word-based and video-based scenarios. Following each scenario, you’ll answer open-ended questions by typing responses. You’ll typically have 3–3.5 minutes to type answers to two questions for each scenario.
In total, the test includes around 11–15 scenarios, mixing video and text prompts that require video or typed answers depending on the section.
Timing & Structure
The full test runs in one sitting online. You’ll have strict time limits on each question — both video and typed responses are timed. There may be optional short breaks (for example, after the video section) to help you reset. Because reactions are completed under strict time constraints, preparation often focuses on improving typing speed, practicing clear communication, and learning to organize your thoughts quickly.
What CASPer Measures
CASPer isn’t about right or wrong answers; it’s about how you think through problems and communicate your reasoning. Test takers should demonstrate empathy and interpersonal skills, ethical judgment, communication and collaboration, professionalism and self-awareness, and problem-solving in ambiguous situations. These competencies align closely with the personal and professional qualities that medical schools seek in future physicians.
Key Takeaways.
The CASPer test is increasingly common in medical school admissions. It’s designed to help schools look beyond your grades and MCAT score to assess the personal characteristics that matter in clinical practice. Understanding the format — a mix of video and written responses under time limits — and what it measures can help you approach the test with confidence. Give yourself time to practice, and you’ll show schools your best self in this unique assessment.
