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.

First-Line Supervisors of Correctional Officers

Directing brig operations and overseeing confined personnel's custody, discipline, safety, and welfare closely matches civilian correctional supervision.

How to prepare: Ask a target corrections agency to assess your documented brig leadership experience against its supervisory entry criteria and identify any required academy training or state correctional officer certification.

What the civilian work involves
  • Supervise and direct the work of correctional officers to ensure the safe custody, discipline, and welfare of inmates.
  • Maintain order, discipline, and security within assigned areas in accordance with relevant rules, regulations, policies, and laws.
  • Maintain knowledge of, comply with, and enforce all institutional policies, rules, procedures, and regulations.
Civilian tools and software (examples)
  • Microsoft Office software

Probation Officers and Correctional Treatment Specialists

Reviewing treatment programs and parole requests and directing rehabilitation programs provides relevant experience for correctional treatment and offender progress assessment.

How to prepare: Compare your education with a target jurisdiction's correctional treatment specialist entry requirements before applying. These roles typically require a bachelor's degree and government-sponsored training, with possible certification testing and a trainee period of up to one year.

What the civilian work involves
  • Prepare and maintain case folder for each assigned inmate or offender.
  • Gather information about offenders' backgrounds by talking to offenders, their families and friends, and other people who have relevant information.
  • Interview probationers and parolees regularly to evaluate their progress in accomplishing goals and maintaining the terms specified in their probation contracts and rehabilitation plans.
Civilian tools and software (examples)
  • Microsoft Word
  • Appointment scheduling software
