The U.S. News Short List, separate from our overall rankings, is a regular series that magnifies individual data points in hopes of providing students and parents a way to find which undergraduate or graduate programs excel or have room to grow in specific areas. Be sure to explore The Short List: College and The Short List: Grad School to find data that matters to you in your college or grad school search.

Med schools may be on a mission to increase enrollment, but that doesn't mean they're accepting just anyone. In fact, some medical schools are being even more selective.

At George Washington University's School of Medicine and Health Sciences, only 2.1 percent of fall 2012 applicants were offered admission, down from 3.1 percent in fall 2010. This drop could be caused by a spike in applicants, which jumped by more than 4,100 between 2010 and 2012, according to data reported by the school.

The D.C.-based med school is not alone in its selectivity. The average acceptance rate at U.S. medical programs for fall 2012 was only 8.3 percent, according to data reported by 114 ranked medical schools in an annual U.S. News survey.

That rate drops to an average of 3.3 percent at the 10 pickiest institutions, making getting into the most selective programs akin to winning the med school lottery.

Mayo Medical School in Minnesota, which tied George Washington with a 2.1 percent acceptance rate, is the only school on the list that isn't located on the coasts. Three California med schools -- Stanford University School of Medicine, University of California--San Francisco and the David Geffen School of Medicine at UCLA -- represented the West Coast.

East Coast schools include top-ranked Harvard Medical School in Massachusetts, as well as the Columbia University College of Physicians and Surgeons in New York and the School of Medicine at Wake Forest University in North Carolina. Schools designated by U.S. News as Unranked were excluded from this list. U.S. News did not calculate a numerical ranking for Unranked programs because the program did not meet certain criteria that U.S. News requires to be numerically ranked.
