"Toward the end of his administration, President Dwight Eisenhower appointed a Joint Study Group to examine the organizational and management structure of U.S. foreign intelligence. Its foremost concern was military intelligence coordination. The final report advanced the concept of a new intelligence organization which would act as the primary point of contact for the military intelligence community--a defense intelligence community, a defense intelligence agency. […] The Defense Intelligence School would be created by Department of Defense Directive 5105.25, establishing the school as a professional educational institution attached to DIA [Defense Intelligence Agency]. Its mission was to enhance the preparation of selected military officers and key DoD civilian personnel for important command, staff and policy-making positions in the national and international security structure; prepare DoD military and civilian personnel for duty in the military attaché system; and assist the broad career development of Department of Defense military and civilian personnel assigned to intelligence functions. The first class graduated in June 1963. […] In December 2006, DoD Instruction 3305.1 changed our name to the National Defense Intelligence College. The DoD Instruction was revised again in February 2011 to reflect the current designation -- National Intelligence University [NIU] -- and the Director of National Intelligence formally and publicly announced that change as well as the expanded mission and vision of the NIU during the August 2011 convocation of the class of 2012."
