The State Department’s website (www.state.gov/m/fsi) provides this description of the training offered at its Foreign Service Institute:
“The Foreign Service Institute is the Federal Government's primary training institution for officers and support personnel of the U.S. foreign affairs community, preparing American diplomats and other professionals to advance U.S. foreign affairs interests overseas and in Washington. At the George P. Shultz National Foreign Affairs Training Center, the FSI provides more than 450 courses – including some 70 foreign languages – to more than 50,000 enrollees a year from the State Department and more than 40 other government agencies and the military service branches.
The Institute's programs include training for the professional development of Foreign Service administrative, consular, economic/commercial, political, and public diplomacy officers; for specialists in the fields of information management, office management, security, and medical practitioners and nurses; for Foreign Service Nationals who work at U.S. posts around the world; and for Civil Service employees of the State Department and other agencies. Ranging in length from a half-day to 2 years, courses are designed to promote successful performance in each professional assignment, to ease the adjustment to other countries and cultures, and to enhance the leadership and management capabilities of the U.S. foreign affairs community. Other courses and services help family members prepare for the demands of a mobile lifestyle and living abroad. FSI has one program available to the general public.”
