Graduate-Level Security Studies

The NSA department is one of the 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 to analyze how the U.S. government makes foreign policy decisions and the role the U.S. plays in the world.
