Graduate-Level Security Studies

The NSA department is one of three core departments at NWC and offers two courses that lead to the master's degree: national security decision making (NSDM) for senior-ranking students and theater security decision making (TSDM) for mid-ranking students. These eight-credit hour courses provide a broad interdisciplinary foundation in contemporary security studies including international relations, regional studies, foreign policy analysis and decision making.

National Security Decision Making Course

National Security Decision Making (NSDM) is designed to engage senior-rank students in the current and future complexities of a rapidly evolving national and international security environment. The course offers a broad interdisciplinary curriculum in contemporary security studies that encompasses a diverse spectrum of global and regional issues and perspectives, but with particular emphasis on U.S. decision making challenges and processes at the national strategic level.
