A Case Report and Literature Review
US News & World Report’s annual ranking of the nation’s best graduate schools was released earlier today, giving the University of Rochester School of Medicine and Dentistry a noticeable boost. Among the best research medical schools, Rochester scored #29, its highest ranking since 2002. In the primary care schools category, the University of Rochester was listed as the #15 best medical school, up slightly from last year. The rankings are widely used by college students when choosing medical schools which to apply.
Both scores were aided by improvements in the school’s selectivity as it accepts students with higher grade point averages in their undergraduate studies and better performance on medical school entrance exams. Among research schools, the University of Rochester also outpaced more schools in research funding than it did in last year’s ranking.
