This past January, the rules changed for Sailors with more than 20 years of service. NAVADMIN 030/09 announced career continuation boards for chief, senior chief, and master chief petty officers. Annual boards, starting next month, have an unusual effect; bringing more, and less, equality to the Navy.
The equality is easy to see; chiefs with over 20 years are now relatively on par with junior Sailors, their retention based on some seemingly objective review of their performance. Previous NAVADMINs 017/09 and 161/09 extended the Perform to Serve (PTS) screening program to include E-6 and below Sailors under 14 years of service in a retention quota system, although PTS also allows conversion to another rating.
The inequality is a bit less obvious. First, two "protected classes" have been created; chiefs, senior chiefs, and master chiefs under 20 years, and petty officers between 14 and 20 years, are not subject to career screening. Sailors in other situations are also exempt, but unconditional exemption is guaranteed for these two groups.
