KCUMB has some linkage programs from some local undergraduate schools that allow students to skip their senior year of college and begin medical school... typically these are many of the students that don't end up doing well. I could be wrong, but I believe a couple of these bridge programs don't require the mcat. Skipping a year of undergrad and basically not knowing how to study correctly ends up hurting these students. Most of the students that are "held back" join the masters program and then matriculate the following year. The graduation rate (at least in the last 10 or so years) has been in the mid 90's.
I don't think KCUMB will ever have a class size of 300. Weaver auditorium was knocked down to make room for the new classrooms, so there really isn't a good spot on campus to host guest speakers/lectures, conferences, and other ceremonies. KCUMB is currently on a huge research kick, and they host a research symposium once a year that hosts speakers and students from around the country. I imagine this is why one of the rooms could potentially hold 400 students.
I asked a family friend who is an associate dean about the possibility of a nursing program. From what he knows, there's never been a plan to start a nursing school. There are already way too many nursing programs in the Kansas City area. He said the only thing he has ever heard of as far as expansion would be the start of PA program in the distant future. With only two classrooms, I can't really see this happening but who really knows.
The only reason more people would potentially be kicked out of school is that the new dean has made it very clear his emphasis is on board scores and matches. The remediation policy has become stricter on repeat offenders, but I don't think it's anything to worry about. When you have a class of 270 students, its not uncommon for a few students to drop out because of grades, health, family crisis, or the fact that maybe their heart was never in it and they decide medical school isn't for them. I would be willing the bet that almost everyone on SDN will be in the 96% that makes it through.
