Foreign Service Institute: Training the Architects of U.S. Diplomacy
The Foreign Service Institute (FSI) serves as the premier training institution for the United States Foreign Service community. As the primary engine for professional development within the U.S. Department of State, the FSI prepares diplomats and other essential professionals to advance American foreign policy objectives, both in Washington, D.C., and at overseas missions.
Headquartered at the National Foreign Affairs Training Center in Arlington, Virginia, the institute provides a massive scale of educational resources. Each year, more than 225,000 enrollees—drawn from the Department of State and over 50 other government agencies and military branches—utilize FSI's extensive curriculum to sharpen their expertise.

A Legacy of Diplomatic Excellence
The FSI was not created in a vacuum; it was the culmination of several predecessor programs, including the Consular School of Application (1907) and the Wilson Diplomatic School (1909). Following legislation signed by President Truman in 1946, Secretary of State George C. Marshall officially established the Institute on March 13, 1947.
Initially located in the Mayfair Building in Washington, D.C., the FSI underwent significant evolution. A pivotal moment occurred in 1954 following the Wriston Report, which led to a curriculum overhaul that placed a much heavier emphasis on specialized training and language proficiency. In October 1993, the institute moved to its current permanent home in Arlington, Virginia.

To support global operations, the SLS maintains a network of language field schools in locations such as Taipei, Yokohama, Seoul, and various regions across the Middle East, North Africa, and Asia.

School of Professional and Area Studies (SPAS)
SPAS focuses on the "tradecraft" of diplomacy. This includes training in consular affairs, political and economic affairs, and public diplomacy. It also provides deep dives into the socio-cultural and political landscapes of specific world regions. Notably, it houses the Center for the Study of the Conduct of Diplomacy (CSCD), which analyzes recent diplomatic experiences to establish best practices for future missions.
School of Applied Information Technology (SAIT)
In an increasingly digital world, SAIT ensures that foreign affairs professionals are equipped with essential technical skills. The school provides training ranging from general business applications to specialized IT management and technical training for Information Management Specialists.

The LMS is responsible for developing the next generation of leaders. It offers mandatory and elective training for supervisors and managers at all levels, from entry-level staff to senior executives, including crisis management training for overseas environments.
The Transition Center (TC) and Office of the Historian (OH)
The Transition Center assists employees and their families in navigating the unique challenges of a mobile, international lifestyle. Through its Center of Excellence in Foreign Affairs Resilience (CEFAR), it provides training for performing in high-stress or high-threat environments.
