Graduate schools have varying requirements regarding language studies, with some programs, particularly in fields like business or certain sciences, potentially valuing language proficiency. Historical context indicates that institutions like the University of Michigan had language requirements in the past, specifically for understanding scientific literature in languages such as German, French, or Russian. However, these requirements may have evolved, and prospective students are encouraged to check the specific policies of the graduate schools they are interested in. Overall, while language courses can be beneficial, they may not be essential for all graduate programs.
