1. Make it so that decisions actually mean something about the applicant. Too often, both from my personal experience and learning about others', it seems like there is a hefty amount randomness and subjectivity in the current process. I don't feel like my acceptances mean more than "yeah, he fit the bill, let's flip a coin to see whether we should accept him or not" when there are so many others like myself that didn't get accepted. Similarly, it's hard to understand when someone you may believe to be equally deserving gets in and you don't. It also leads to situations where people get into their dream schools (awesome!) but then others that really should have gotten in somewhere, end up without any offers, even though there aren't substantive differences in achievements or capability.
There are many strong applicants applying to nearly all the same programs and so I would strongly support a system that either eliminated or reduced the number of applications. Whether it's by making the process similar to the match process, adopting the UK's UCAS limit to 5 schools, or even something like @
LizzyM suggested, my hope would be that instead of having to decide between 20 "equal" applicants, schools may only have to make the decision between 5 of them, or perhaps none!
I could also support a mandate where a school's number of interview spots is limited by the size of it's incoming class/the number of acceptances it will offer. Have the number of interviews be somewhere around 250-300%. If I'm going to take additional time out of my life, travel, and then participate in what is, most of the time, a rather unpleasant experience of being judged, I ought to feel like I have a
good chance of being accepted. The fact that a school may admit under 25% of the people the people they interview simply tells me that they have no clue what they are really looking for and seems quite unprofessional.
2. As someone who originally thought that MMI's were a great idea, I'm not so sure now. Yes the claims that they look for qualities that may not be easily ascertained otherwise and that they help to make the interview more fair through the use of raters, rather than a few interviewers who you may or may not get along with, are noble pursuits. Nonetheless, in practice I have come to see them as completely robbing the interview of all humanity. At the very least, they should be combined with a more traditional interview.
3. Shorten the whole process. Applying in June and potentially not knowing where you'll be over a full year later is ridiculous. Decrease AMCAS verification time and set a real interview season that ends by New Year's.
