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.

Electrical and Electronic Engineering Technologists and Technicians

Electronic test-equipment calibration, adjustment, and repair provide a foundation for electronics testing and equipment maintenance.

How to prepare: Complete a hands-on electronics troubleshooting course that covers schematic interpretation and component-level fault isolation.

What the civilian work involves
  • Modify, maintain, or repair electronics equipment or systems to ensure proper functioning.
  • Replace defective components or parts, using hand tools and precision instruments.
  • Set up and operate specialized or standard test equipment to diagnose, test, or analyze the performance of electronic components, assemblies, or systems.
Civilian tools and software (examples)
  • Microsoft Excel

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Test-equipment repair and metrology documentation transfer to industrial equipment diagnostics and maintenance records, particularly for technicians with journeyman troubleshooting experience.

How to prepare: Take a practical industrial-electronics repair course using equipment representative of the employers you plan to target.

What the civilian work involves
  • Test faulty equipment to diagnose malfunctions, using test equipment or software, and applying knowledge of the functional operation of electronic units and systems.
  • Maintain equipment logs that record performance problems, repairs, calibrations, or tests.
  • Set up and test industrial equipment to ensure that it functions properly.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS

Training & Development

Choose credentials for your target role. COOL funding markers describe program listings, not a guarantee of eligibility or funding.

Getting Started

  • Associate Electronics Technician (CETa)

    Demonstrate foundational knowledge of electronic theory, circuits, test equipment, and work procedures for electronics testing and repair roles.

    Eligibility and preparation: ETA describes CETa as designed for technicians with less than two years of electronics experience or training, not as requiring two years of experience; the hands-on component is optional.

    For: Electrical and Electronic Engineering Technologists and Technicians, Electrical and Electronics Repairers, Commercial and Industrial Equipment

Notes & Sources

  • The duty description places routine test-equipment repairs, modifications, and adjustments under direct supervision; increasingly complex equipment work and advanced troubleshooting are described at the journeyman level.
