thirteen at the University of Cambridge, and four at Imperial College London. Of these scholars, 46 were studying arts and social sciences while 23 were studying science, engineering or mathematics. Comparison to other post-graduate scholarships In structure and selection criteria, the Scholarship is most similar to the American Rhodes Scholarship and the Fulbright Program. Like the Fulbright available for study in the United Kingdom, Marshall Scholars can study at any university in the UK. However, under the Fulbright, applicants compete in separate pools for 43 specified universities of varying selectivity, except for two awards tenable at any university. The Marshall Scholarship is more flexible than the Rhodes Scholarship, in that Marshall Scholars can study at any British university, and can also attend a different university each year during a Scholar's tenure. In addition, a limited number of one-year Marshall scholarships are available. Unlike Rhodes Scholars, Marshall Scholars must be American citizens (in comparison, approximately eighty Rhodes Scholarships are given annually to citizens of over a dozen countries). In the process, the Marshall Scholarship is roughly as selective as the Rhodes and Mitchell Scholarships: the Marshall was awarded to 3.4 percent of university-endorsed applicants in 2014, compared to 3.7 percent for the Rhodes in 2014, and 3.2 percent for the Mitchell Scholarship in 2017. The Gates Cambridge Scholarship is slightly more selective with 1.3% of applicants receiving an award. Also, because the selection processes of the scholarships discussed above differ, the likelihood that an applicant will be granted a final round interview is different for each scholarship. In 2014, 15.9 percent of university-endorsed applicants for the Marshall Scholarship received a finalist interview, compared to 24 percent of Rhodes applicants and 5.4 percent of Mitchell applicants. While the selection committees continue to emphasize academic potential, over time "the Marshall program has become more Rhodes-like, stating that it is seeking persons who also demonstrate leadership potential." In general, "nearly all Rhodes Scholars are willing to admit that, by and large, the Marshalls are superior if one looks just at grade point averages and other signs of academic achievement," but this is a point of both "admiration" and "disdain." Walter Isaacson, describing Rhodes Scholars as "fairly intelligent, well-rounded, honest people who could be counted on to be upstanding citizens," has said that "the real geniuses...were the Marshall Scholars," perhaps because of the expectation that Rhodes Scholars be "all-rounders." In practice, the Marshall and Rhodes
