What is CASPer?

CASPer (Computer-based Assessment for Sampling Personal Characteristics), a 90 minute web-based test, is a component of the application process used by certain medical schools and nursing programs, including the Michael G. DeGroote School of Medicine at McMaster University ("McMaster"), University of Ottawa (uOttawa), New York Medical College (NYMC) and Rutgers Robert Wood Johnson Medical School (Rutgers RWJ).

CASPer is an online test used to help screen applicants as part of the medical school / nursing program's application process, as one of several criteria assessed in determining candidates' invitations to interview.

How long has CASPer been used?

CASPer was first officially implemented back in McMaster’s 2010-2011 application cycle as a method to evaluate candidates’ interpersonal and critical thinking skills. This was a change from McMaster’s previous application screening process which required candidates to write a series of short essays.

What is the structure of the CASPer test?

CASPer is a 90-minute test consisting of 12 stations.  Each section follows a similar format consisting first of a short video or other directed text, followed by 2-3 questions relating to the material presented in the video or question stem.  Some sections are prompted by situational challenges displayed in short video clips; others are prompted by self-reflective questions. The applicant has 5 minutes to answer all questions in a given section. The exam includes a 15 minute break at the halfway mark as well as an exit survey given at the end of the final section.

Is there an example of a CASPer video that I can watch?

Visit, the website of the official CASPer test administrator, for a sample CASPer Test that you can take, which includes two sample videos.

McMaster has provided a sample video on their website to familiarize students with the CASPer exam. You can access the video here.

Astroff has designed its own Sample CASPer Video that you can watch:

How has McMaster evaluated candidates on CASPer in past years?

In one of McMaster’s research article outlining CASPer, the authors noted the following criteria used by judges to grade the applicants’ answers: communication skills, strength of the argument raised, suitability for a career in medicine, and overall performance on the scenario. To do well on CASPer, it is integral to have well-communicated, persuasive, knowledgeable, relevant answers to each question.
