With General Staff School, the practice of direct transition from Army War Academy to Staff College was abolished, and admission into Staff College now required two years of field service following the Army War Academy. Afterward, the officers were subjected to examinations, and those who passed the exam were admitted into the college as Staff Officer candidates. Following the Allied occupation of Constantinople on 16 March 1920, military schools were dissolved by the victors of the First World War; nevertheless, the Staff College was managed to continue its activities until April 1921 at the Şerif Pasha Mansion in Teşvikiye, Constantinople where it had been moved on 28 January 1919. Since all instructors and students went to Anatolia to join the National War of Independence, the Staff College was closed down.
