The National Intelligence University (NIU) is a federally chartered research university in Bethesda, Maryland operated by and for the United States Intelligence Community (IC) as its staff college of higher learning in fields of study central to the profession of intelligence and national security. A small, highly selective non-residential university, NIU awards undergraduate and graduate degrees, a graduate certificate, and prestigious research fellowships to prepare personnel for critical positions in the IC and the broader national security enterprise. Since 1963, more than 80,000 military and civilian students have attended the university. Originally located at Defense Intelligence Agency headquarters at Joint Base Anacostia–Bolling in Washington, D.C., NIU's primary campus is now located just up the Potomac River at Intelligence Community Campus-Bethesda (ICC-B) with four additional locations around the world.
