Both the Air Force and the Army offer a Non-Commissioned Officer Development Ribbon.   The Navy, Marine Corps and Coast Guard have no equivalent decorations.  These military awards honor those non-commissioned officers who have completed a prescribed leadership course at an NCO training school.  The Air Force does not have corresponding military medals for this award.

The Air Force version is called the Non-Commissioned Officer Professional Military Education Graduate Ribbon.  These military ribbons are presented to airmen for completion of prescribed NCO development programs.  The Air Force programs include Airman Leadership School, Non-Commissioned Officer Academy, and the Senior Non-Commissioned Officer Academy courses.  

Additional awards of the Air Force Non-Commissioned Officer Professional Military Education Graduate Ribbon are denoted by Oak Leaf Clusters.  These military ribbons are worn below the Armed Forces Reserve Medal and above the Air Force Basic Military Training Honor Graduate Ribbon in the order of precedence for all military medals and ribbons.   These military awards are available as lapel pins, and as traditional slide on ribbons or the newer custom thin ribbon versions that have a trimmer, more professional appearance.
