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.

Human Resources Specialists

Administering personnel information in MCTFS, developing personnel procedures, and advising on benefits transfer directly to HR records and policy support.

How to prepare: Complete a civilian HR course covering EEO and ADA requirements to bridge military personnel policy experience to civilian employment practices.

What the civilian work involves
  • Interpret and explain human resources policies, procedures, laws, standards, or regulations.
  • Prepare or maintain employment records related to events, such as hiring, termination, leaves, transfers, or promotions, using human resources management system software.

First-Line Supervisors of Office and Administrative Support Workers

Supervising personnel administration and coordinating manpower and pay reporting align with directing administrative staff and reviewing payroll-related records.
