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.

Training and Development Specialists

Preparing training materials and planning, coordinating, and supervising military training programs directly supports civilian course-material development and training delivery coordination.

How to prepare: Build a portfolio sample using a non-sensitive topic you know well, including a learner guide, training schedule, and assessment that demonstrates how you would check learning.

What the civilian work involves
  • Obtain, organize, or develop training procedure manuals, guides, or course materials, such as handouts or visual materials.
  • Offer specific training programs to help workers maintain or improve job skills.
Civilian tools and software (examples)
  • Microsoft PowerPoint
  • Adobe Acrobat
