Many actions can trigger an officer's availability for an assignment.
Officer Assignment Team members at the Air Force Personnel Center are charged with identifying officers who are likely to move within the next six to nine months. At this time, the commander or designated preference worksheet reviewer, usually a division chief, should meet with the officer to discuss the type and level of assignment most appropriate for their professional development. This will give officers and commanders generalized guidelines for the type of assignment that officer should seek. Assignments will be made based upon Air Force requirements, officer professional development and personal preferences. They can view an Authorizations Listing which will list all unclassified manpower requirements in their career field.
