Candidates for admission generally must both apply directly to the academy and receive a nomination, usually from a congressman. The candidates lacking in academics can potentially receive a nomination to the Naval Academy Preparatory School located in Newport, Rhode Island. Students are officers-in-training and are called "Midshipmen". The Navy pays for the Midshipmen's college expenses in exchange for the students serving in the military upon graduation. About 1,300 "plebes" enter the Academy each summer for the orientation program, this class consists of not only high school students but also enlisted Sailors and Marines. Only about 1,000 Midshipmen graduate after the four years. Graduates are usually commissioned as Ensigns in the Navy or Second Lieutenants in the Marine Corps, and occasionally as officers in the US Air Force, US Army, and U.S. Coast Guard. The academic program grants a bachelor of science degree. Midshipmen get grades on a broad academic program, military leadership performance, and mandatory participation in competitive athletics. Midshipmen are required to adhere to the Academy's Honor Concept.
