As the application deadline approaches we are getting a lot of questions about the CASPer testing requirement for McMaster MD Program Applicants.  Please note:  the three remaining CASPer test dates (Sept 17, Oct 15 and Oct 25) are all acceptable test dates for anyone applying to McMaster through OMSAS. 

Applicants must finalize and submit their medical school application to OMSAS in order to obtain the necessary OMSAS reference number to register for a CASPer test.  This means you may submit your OMSAS application by the Oct 2nd deadline and then register for one of the October CASPer test dates with no concern.  

If you have further questions about registering for CASPer or if you have difficulty with any aspect of the registration or testing process please contact the CASPer support team at 

*Note: with respect to the November 8th deadline posted on the CASPer website, applicants will not receive their CASPer scores. CASPer scores are sent directly to the programs through an online Portal. The Nov 8th deadline is the last date that the applicant can log into their CASPer profile and add another program to their distribution list if they so choose.  

Computer-Based Assessment for Sampling Personal Characteristics

All applicants to the Michael G. DeGroote School of Medicine, McMaster University will be required to complete a 90 minute computer-based test, called CASPer™, as part of the selection process.

CASPer™, the Computer-based Assessment for Sampling Personal characteristics, is a web-based assessment of interpersonal skills and decision-making, to be completed at a computer.  Successful completion of CASPer™ is required to maintain applicant eligibility.

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.  In implementing CASPer™, we are trying to further enhance fairness and objectivity in our selection process. 

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.

Important note for 2018 applicants 

All applicants to the Michael G. DeGroote School of Medicine must write the CASPer annually.  You need your current (2018) application cycle OMSAS number in order to release your CASPer scores to McMaster University. You receive this number after you have submitted your completed application to OMSAS.  Please visit to sign up for CASPer.​
