You are not naive. This is pretty new. The class of 2018 is the first class they collected data on. I haven't seen the data but my school was one of the ~70 schools that participated. The goal is to provide schools with more actionable residency application data than charting outcomes has. A survey was sent to all the 2018 people shortly after match last year asking us for info like step scores, how many classes we honored, research experience, extracurriculars, awards, etc. The main advantage/purpose of this being that it also asked us to select the programs we applied to, where we got interviews, how we ranked the programs and where we matched on our list. My understanding is that the schools that participated will be able to see the anonymized data so that they can advise students on what kinds of students get interviews and/or match at specific programs within specialties rather than the specialty only data that NRMP puts out in charting outcomes. It's frankly pretty shocking it has taken this long for someone to do this. I assume they are collecting/adding the 2019 data and if your school is one of the ~70 involved, your admin should have access.
