All Enginemen are required to take their current rating exam for their next advancement exam according to a NAVADMIN. The Engineman community is currently overmanned at 153% while the Machinist's Mate community is undermanned. This means that advancement for Enginemen will be below the Navy average for the next 2-3 years due to lack of vacancies, while advancement will be favorable for Machinist's Mates. Enginemen wishing to stay in their community should consider converting to Machinist's Mate, as orders and PTS approvals will be more readily available in the undermanned MM community in the future.
