Marine Corps Institute

The Marine Corps Institute, commonly referred to as MCI, develops and maintains a curriculum of Marine Corps education. Subjects include infantry strategy/tactics, leadership skills, MOS qualifications, personal finance, and mathematics. Completion of MCI courses is generally required for promotion to the next Marine enlisted rank.

History
Since February 1920, the Marine Corps Institute has facilitated the training and education of individual Marines. MCI ensures access to products and provides opportunities to improve performance, to enhance Professional Military Education, and to provide promotion opportunity, together with sponsors of Marine Corps education and training programs.

MCI also coordinates and executes the Hosting and Parade Escort plan for the Evening and Sunset Parades. It provides ceremonial Officers and NCOs for the Parade Staffs and other assigned ceremonies in order to promote the Marine Corps’ heritage and to enhance the Marine Corps’ image to the general public.

MCI Company also maintains Individual MOS and Battle Skills proficiency both in garrison and field environments to prepare the individual Marine for combat.

The Marine Corps Institute is located in the historic Washington Navy Yard in the United States capitol. MCI is administratively organized as part of Marine Barracks, Washington, D.C. and supports the Barracks.

Accreditation
The Marine Corps Institute has been accredited by the Accrediting Commission of the Distance Education and Training Council (formerly the National Home Study Council) since 1977.

Controversy
The Marine Corps Institute implemented ROLE exams to reduce cheating facilitated by the "MCI Bible", a book commonly located in Marine Corps units that contained all the answers to every single MCI available. MCI's utilized SCANTRON technology which made it easier to cheat before they began to phase out printed exams.
