Computer-Based Assessment for Sampling Personal Characteristics (CASPerTM)

All applicants to the Michael G. DeGroote School of Medicine, McMaster University will be required to complete a 90 minute online assessment, called CASPer™, to be eligible for admission.

CASPer™, the Computer-based Assessment for Sampling Personal characteristics, is a online test that assesses for the personal and professional characteristics we believe are important for successful applicant screening.  

It is the responsibility of the applicant to ensure that they are able to have dependable access to CASPer™ online. No exceptions will be provided for applicants unable to take CASPer™ online due to being located at an international site in which internet is not dependably accessible due to technical or political factors.

CASPer™ assesses for non-cognitive skills and interpersonal characteristics that we believe are important for successful students and graduates of our program, and will complement the other tools we use for applicant screening.

The CASPer™ test is comprised of 10-12 sections of video and written scenarios.  Following each scenario applicants are required to answer a set of probing questions under a time contract.  Each response is graded by a different rater, giving a very robust and reliable view of personal and professional characteristics important to our program.  No studying is required for CASPer™, although you may want to familiarize yourself with the test structure at and ensure you have a quiet environment to take the test.

To sign up for CASPer visit:

Choose: Canada/English/Undergraduate Medicine
Your test is called: CSP-10201 - Canadian Professional Health Sciences
School: McMaster University

Note: McMaster ​does not require Snapshot for the 2021/2022 application cycle.

Frequently Asked Questions

  • Can I take CASPer after the October 1st application deadline?

    Yes – the McMaster CASPer test dates will be available in July 2021. Visit

  • What if I am applying to a medical school that requires me to take CASPer in August or September, such as Dalhousie School of Medicine? In this case, do I write it twice?

    No, you can only write the Canadian Professional Health Sciences CASPer test once/application cycle.  If you must write CASPer in August or September [for schools with an earlier test date requirement, such as Dalhousie School of Medicine] and are also applying to McMaster, you must add McMaster to your distribution list, once you have received your OMSAS number.  You receive your OMSAS number when you submit your application – deadline, October 1st). Your distribution list is on your test record, on the reservations page at To add to your distribution list, click the small pencil icon, select schools and submit payment to secure your additions.
  • Are there any situations where I would write CASPer more than once/application cycle?

    Yes.  If you are applying to the University of Ottawa Medical School French stream (and therefore you are writing CASPer in French), you would need to write it a second time, in English, for McMaster.  If you are applying to programs that use a different version of CASPer (i.e. Nursing Programs), you would need to write CASPer for each program (the tests are different for medical school and other programs).  If you are applying to a medical school outside of Canada, you would need to write CASPer for the Canadian medical school and additionally for the US or international medical school(s) you are applying to.
