The Woodrow Wilson School offers an undergraduate concentration in public and international affairs; it is a multidisciplinary major in which each student, in consultation with the director, creates an individual program of study that combines techniques of analysis from the social science disciplines and courses that give the student substantive depth in a particular policy area. The program of study for all students includes a core course on Democracy, two simulated policy exercises done in seminars during the junior year, and a year-long senior independent project in policy analysis. The curriculum is not specifically designed to train students for government, but one of its goals is to encourage interest in, and instill respect for, public service. Woodrow Wilson School students enter with a wide variety of interests and spend their lives after graduation in a diverse range of careers, including government, politics, teaching, journalism, law, medicine, business, and non-governmental organizations.

Each year the School admits 90 Princeton undergraduates who are selected on the basis of their academic record, strength of preparation, commitment to the study of public and international affairs, and the perspectives or experiences they would bring to the School. Among the 90 students admitted each year, most are concentrators (majors); a smaller number are admitted as certificate students. Certificate students typically concentrate in the sciences, engineering or the humanities while enrolled in the Woodrow Wilson School; they have fewer course requirements than the concentrators.
