Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Shipping, Receiving, and Inventory Clerks

Processing inventory records and stock listings for aviation repair parts transfers directly to civilian inventory recordkeeping and stock control.

How to prepare: Practice reconciling a sample parts inventory in Microsoft Excel, documenting discrepancies between stock records and shipment contents.

What the civilian work involves
  • Examine shipment contents and compare with records, such as manifests, invoices, or orders, to verify accuracy.
  • Requisition and store shipping materials and supplies to maintain inventory of stock.
  • Record shipment data, such as weight, charges, space availability, damages, or discrepancies, for reporting, accounting, or recordkeeping purposes.
Civilian tools and software (examples)
