国际关系（IR）计划是塔夫特塞大学本科课程的标志。该课程本质上是跨学科的，它从社会科学，人文科学，艺术和自然科学中吸取教职人员和课程，要求学生从多个角度参与世界问题。国际关系专业的学生研究区域历史，经济学，政治和文化，全球健康，营养和环境，战争的原因和后果以及和平条件，思想通过全球实践和行为（包括人权和移民）的传播，以及个人如何通过性别，阶级，宗教，种族和族裔等角度看待自己与世界的关系。许多学生将在塔夫茨大学国际关系研究生院，弗莱彻法律与外交学院上课，这是美国历史最悠久，也是最杰出的国际关系学院之一。鼓励
The International Relations (IR) program is a hallmark of Tufts undergraduate curriculum. Inherently interdisciplinary, the program draws faculty and courses from the social sciences, humanities, arts, and natural sciences, requiring students to engage world problems from multiple perspectives. IR majors study regional history, economics, politics, and culture, global health, nutrition, and the environment, the causes and consequences of war and the conditions of peace, the spread of ideas through global practices and behaviors including human rights and migration, and how individuals perceive themselves in their relationships to the world through prisms such as gender, class, religions, race, and ethnicity. Many students will take classes at Tufts graduate school of international relations, the Fletcher School of Law and Diplomacy, which is the oldest and one of the most distinguished schools of international relations in the United States.The IR program encourages students to undertake study abroad, either for a summer, a semester, or for a full academic year. Tufts sponsors study abroad programs in many places, including Chile, China, France, Germany, Great Britain, Hong Kong, Japan, and Spain. Many students also devise - with the help of an advisor - a study abroad program specifically tailored to their particular cultural, linguistic, economic, political, or sociological research interests.Language study is required for all IR majors because language is such a valuable tool in understanding the characteristics of particular cultures. It is also the precondition for effective cross-cultural communication. A recent class of IR graduates used over 15 different languages to complete their degrees.This concentration addresses the conceptual connections between issues of global health, nutrition, the environment and sustainable development as they relate to international affairs. As a functional concentration, it also aims to provide the analytic and scientific knowledge sets to prepare majors considering advanced study or professional entry into a related field.
