How long does it take to become an investigator?

It takes at least two to four years to become an investigator. Some places of employment may hire a high school graduate and provide on-the-job training, but typically, employers look for college graduates who majored in criminal justice.

Additionally, investigators may be required to be licensed, mainly as private investigators depending on the state. Those requirements vary from having a bachelor's degree to having relevant work experiences such as law enforcement or military officer.
