Generally, a nomination from a member of Congress or the Vice President is required to receive an appointment to the USNA. A nomination does not guarantee an appointment; in a typical year about 38% of nominees receive an appointment. Currently each member of Congress and the Vice President can have five appointees attending the Naval Academy at any time. Other nomination sources include the Secretary of the Navy, who may appoint 170 enlisted members of the regular and reserve Navy and Marine Corps to the Naval Academy each year, and the President may nominate an unlimited number of children of career military personnel for up to 100 appointments each year. Additionally, children of Medal of Honor recipients and select cadets of JROTC Honor Unit with Distinction units do not need a nomination but need only qualify for admission. The United States Merchant Marine Academy only accepts nominations from members of Congress. There are currently no Presidential, Vice-Presidential, military-affiliated, JROTC-honor unit, ROTC or Unit Commander, or Medal of Honor nominations permitted to the USMMA.
