U.S. News and World Report regularly ranks medical research schools in the U.S. Rankings depend on factors such as assessments by peers and residency directors and average research activity per faculty member. Research activity measurements are based on the total amount of funding awarded through grants from the National Institutes of Health. According to Arizona State University, such rankings wield power because a highly productive research faculty leads to more intellectual cachet and thus more research funding.
