United States Chief petty officer is an E-7
enlisted rank in the
U.S. Navy and
U.S. Coast Guard, just above
petty officer first class and below
senior chief petty officer. Chief petty officers are classified as senior
non-commissioned officers. The grade of chief petty officer was established on April 1, 1893, for the U.S. Navy. The
U.S. Congress first authorized the U.S. Coast Guard to use the promotion to chief petty officer on 18 May 1920. Unlike petty officer first class and lower rates, advancement to chief petty officer in the U.S. Navy not only carries requirements of time in service, superior evaluation scores, and specialty examinations, but also carries an added requirement of
peer review. A chief petty officer can only advance after review by a selection board of serving master chief petty officers, in effect "choosing their own" and conversely not choosing others. ==Insignia==
