The Professional Service Semester (PSS) helps students secure graduate-level internships, jobs, or consultancies in international organizations in the U.S. and abroad. The program is designed for graduate students in the International Environmental Policy (IEP) and Nonproliferation and Terrorism Studies (NPTS) graduate programs. 

Students can earn up to 4 units of workshop credits in January and 6 units for the field course during the regular spring, summer or fall semesters. Students should consult their academic advisor regarding additional credits if needed. 

PSS Pre-Registration Deadlines: Students should pre-register three months in advance of the start of their practicum. 


Estimated registration form completion time: 30 minutes (students are asked to indicate some of the places they would like to work)

Get a Head Start on Your International Career

For many students, the practicum experience acts as a stepping stone to a future career. The program’s networking possibilities and international exposure are just a few of the benefits students receive through their participation. An practicum assignment complements a student’s degree focus by providing an applied learning environment for students to develop skills and knowledge not covered in traditional classes.
