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.

Non-Destructive Testing Specialists

Your experience approving NDT procedures and workmanship standards, examining personnel, and monitoring inspection performance transfers directly to civilian NDT work.

How to prepare: Ask a prospective employer to assess your existing certifications and documented method-specific military training and experience against its written practice and applicable customer requirements. For jobs using SNT-TC-1A, employer certification is required under that written practice and is separate from ASNT third-party certification.

What the civilian work involves
  • Interpret or evaluate test results in accordance with applicable codes, standards, specifications, or procedures.
  • Prepare reports on non-destructive testing results.
Civilian tools and software (examples)
  • Microsoft Excel
  • Microsoft Word
