Detectives and Criminal Investigators

P12A experience with crimes against persons and property, testimonial evidence, and investigation reports directly overlaps civilian criminal casework.

How to prepare: Request an entry-eligibility review from a target agency before applying; most police and detectives must complete an agency academy and on-the-job training. Education requirements range from high school to a degree, candidates usually must be at least 21 and meet physical and personal standards, and citizenship rules vary, with U.S. citizenship required for federal officers.

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.
