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.

Detectives and Criminal Investigators

Leading CGIS criminal investigations as a senior special agent directly overlaps with civilian criminal-investigation work.

How to prepare: Compare a target agency's entry route with your CGIS record and plan for its academy and supervised training, including state and local law. Entry requires at least a high school diploma or equivalent, sometimes college coursework or a degree; candidates usually must be at least 21 and meet physical and personal standards, with U.S. citizenship required federally and in most state and local jurisdictions.

What the civilian work involves
  • Obtain facts or statements from complainants, witnesses, and accused persons and record interviews, using recording device.
  • Record progress of investigation, maintain informational files on suspects, and submit reports to commanding officer or magistrate to authorize warrants.
  • Prepare charges or responses to charges, or information for court cases, according to formalized procedures.
Civilian tools and software (examples)
  • Microsoft Office software

Private Detectives and Investigators

CGIS criminal-investigation leadership provides directly relevant investigative experience for private casework.

How to prepare: Compile your military investigation work history for comparison with the licensing experience criteria in your intended state and locality. This occupation typically calls for a high school diploma or equivalent and several years of related experience; most states require a license, with age, experience and other licensing conditions varying by jurisdiction.

What the civilian work involves
  • Write reports or case summaries to document investigations.
  • Conduct private investigations on a paid basis.
  • Search computer databases, credit reports, public records, tax or legal filings, or other resources to locate persons or to compile information for investigations.
Civilian tools and software (examples)
  • Microsoft Word
  • Microsoft Excel
