George Washington University

George Washington University is a highly regarded school in the nation’s capital. Given its Capitol ties, GW boasts an elite international-affairs program as well as a study-abroad participation rate hovering around 50%, and students go everywhere from China to Korea. It is among the priciest institutions in the country, with an average estimated total expense of more than $70,000, although the university employs a fixed-tuition policy, guaranteeing that students' tuition will not change from their first semester for up to five years. GW counts a host of current and former world leaders among its former students.
