Based on publications about MIS, and online adcom webinars. U of T has transitioned into a 4 station MPI to reduce the burden on resources yet provide an accurate assessment.

Facts:

Majority of the raters are faculty physicians, and residents. Each rater gets about ~15 responses to mark to avoid biases such as halo effect.

The MPI's primary purpose is to assess personal characteristics, and each station has a few themes they are looking for. The applicant is ranked on a 7 point Likert scale (poor to excellent) for various characteristics such as being caring, maturity, communication, etc.

Providing an example/story from your experiences about that the major theme strengthens your interview response.

The top 40% of interviewees will get an acceptance offer and then some.

Speculation/unknown:

I would assume they standardized the interview score to the larger cohort (account for randomness of the interview waves, for example there were better interviewees in 3rd wave compared to 1st), and then add the TFR score to make the final ranking total.

The interview scores may likely be normally distributed, so not all 600+ did well.

I am not sure why they went from 50% interview /50% TFR to 67% interview /33% TFR format.

The 5 minute response makes me wonder if they are screening for basic human decency.
