The MMI was introduced into the medical admissions process at the University of Calgary (UofC) in 2006. This report outlines the steps which were involved in its development and our evaluation of the process. The MMI allowed us to interview applicants in one weekend, with fewer interviewers and less time required per interviewer compared to our previous interview process. Most importantly, more than 90% of both the applicants and interviewers found the process to be very acceptable. This process allowed us to ensure that the interview process focused on the non-cognitive traits we are looking for in the students we admit to the UofC.
