The FMS is a "Whole Person Concept" approach that considers your exam score along with other factors to ensure the right Sailors are advanced. The other factors considered for E4/5/6 are Performance Mark Average (how well you perform in your job and as a Sailor), Service in Paygrade (experience in your job), Awards (your accomplishments in your job and as a Sailor), Education Points (self improvement through education (accredited college degrees), and PNA points (credit for doing great on previous exam cycles but not enough quotas available).
For those who are CPO board eligible, the FMS is computed using Performance Mark Average and rating exam score only.
What is your advancement "opportunity?" The quota for each rating - percentage of Sailors that have an opportunity to advance each cycle - is the most important advancement factor. Some ratings have limited quotas, so the Navy works hard to advance the most qualified Sailors using the Whole Person Concept.
There is a saying in the Navy "Choose your rate choose your fate." Being some rates promotion consists of signing your name on the worksheet for advancement. While other rates seem like hell must freeze over before your love one is advanced. Fair system some say its the best others argue against it. Promotion to chief petty officer requires a peer review by senior and master chief petty officers which only the Navy/Guard have and when selected are required to have six weeks of CPO 365 Phase II...........good luck
