The NCO Professional Development Ribbon is issued by the U.S. Army for completion of any prescribed non-commissioned officer development courses. The basic development ribbon is issued for completion of either the Primary NCO Course, Combat Army Course, or Primary Leadership Development Course. If an individual completes additional training, the NCO Professional Development is issued with an award numeral. The highest numeral authorized for the NCO Professional Development Ribbon is “4". The numeral “5" is obsolete and was previously authorized for graduation from the Army Sergeants-Major Academy. This is a slide on ribbon.
