Duke is strongly committed to financial aid and the principle that a student's financial resources should not be a barrier to enrollment. It is among a limited number of schools with a "need-blind" admissions policy, which means all qualified U.S. citizens and legal permanent residents are accepted regardless of their ability to pay for college. Duke guarantees it will meet 100 percent of demonstrated financial need. In recent years, Duke has significantly enhanced its financial aid program to assist both lower- and middle-income families by reducing expected family contributions and loans. It also has expanded aid for international students.
