Vassar confers a Bachelor of Arts (BA) degree in more than 50 majors, including the Independent Major, in which a student may design a major, as well as various interdisciplinary and multidisciplinary fields of study. Students also participate in such programs as the Self-Instructional Language Program (SILP) which offers courses in Hindi, Irish/Gaelic, Korean, Portuguese, Swahili, Swedish, Turkish, and Yiddish. Vassar has a flexible curriculum intended to promote breadth in studies. While each field of study has specific requirements for majors, the only universal requirements for graduation are proficiency in a foreign language, a quantitative course, and a freshman writing course. Students are also encouraged to study abroad, which they typically do during one or two semesters of their junior year. Students (usually juniors) may apply for a year or a semester away either in the U. S. or abroad. Vassar sponsors programs in China, England, France, Germany, Greece, Ireland, Italy, Turkey, Mexico, Morocco, Spain, and Russia; students may also join preapproved programs offered by other colleges. Students may also apply for approved programs at various U. S. institutions, including the historically Black colleges and members of the Twelve College Exchange.
