Chief Petty Officer is the seventh enlisted rank in the U.S. Navy, just above Petty Officer First Class and below Senior Chief Petty Officer, and is a senior non-commissioned officer. The grade of Chief Petty Officer was established on April 1, 1893 for the Navy.Unlike Petty Officer First Class and lower ranks, advancement to Chief Petty Officer not only carries requirements of time in service, superior evaluation scores, and specialty examinations, but also carries an added requirement of peer review.
