During my research into the impact that premed was having on biomedical engineering undergraduate programs I asked for and received historical matriculation data from the AAMC last year. As far as I know I am the only one they have released this information to recently. There apparently is some controversy about providing medical school acceptance data by program within the academic community. My impression is that the AAMC has been pressured by outside forces to not report the medical school acceptance data by program.
The data I received may be useful for those thinking about a premed track in Biomedical Engineering. The upshot is that while BME and total applications to medical school have been increasing between 2003 and 2007 the percentage of BME applicants accepted to medical school has been decreasing (~ 67% vs 57% ) and the total number being accepted have been leveling off. The percentage of applicants with BME degrees remained small at ~1.6% and 2.4% respectively. The percentage of all applicants accepted to medical school also followed the same pattern (~ 50% vs 45% ) because there are a limited number openings each year in the U.S. and they are not increasing significantly. Unfortunately the BME percentage drop is twice that of all applicants. It is difficult to say why the drop is so dramatically different when compared to all other applications. Have there been changes in acceptance criteria? Is there another curriculum that is becoming more relevant? Only time will tell.
