A criminal investigator is an officer of the law who investigates crimes, interviews witnesses, and helps build cases that lead to an indictment. To start a career as a criminal investigator, you need to have several qualifications, which depend largely on the organization for which you plan to work. At the federal level, organizations like the FBI require you to gain acceptance into and complete an intense, five-month training program. For this level, you need significant law enforcement experience, and most applicants hold a degree in criminal justice or a related field. If you want to become a state or local police officer, you still need to attend a police academy, but the qualifications for admission are lower. You need a high school diploma or a GED certificate. However, it can take some time to work up to the level of a criminal investigator or detective.
| Aspect | Investigator | Forensic Scientist |
|---|---|---|
| Required Credentials | High school diploma or equivalent; law enforcement training or certifications often preferred | Bachelor's degree in forensic science, chemistry, biology, or related field; certifications may enhance prospects |
| Work Environment | Law enforcement agencies, crime scenes, investigations | Laboratories, crime labs, research facilities |
| Employer & Industry Usage | Police departments, federal agencies, private investigation firms | Crime labs, forensic laboratories, research institutions |
| Common Search & Comparison Intent | Understanding investigative roles in law enforcement | Understanding scientific analysis in forensic work |
Investigators focus on gathering evidence, interviewing witnesses, and solving cases in the field, often working directly at crime scenes. Forensic scientists analyze physical evidence in labs to support investigations. Both roles are essential in criminal justice but differ in their work environment, credentials, and daily tasks.

WHAT IS CRIMINAL INVESTIGATION?
A description of the business units can be found at: https://www.jobs.irs.gov/about/who/business-divisions
MAXIMUM ENTRY AGE: Provisions of Public Law 93-950 and Public Law 100-238 allow the imposition of a maximum age for original appointments to a law enforcement officer position within the Federal government. The date immediately preceding your 37th birthday is the final date of referral for selection. This age restriction does not apply to preference eligible veterans or land management eligibles. Applicants who are age 37 or over may subtract any of their prior federal service that is in approved position and that is creditable for retirement from their current age to meet this age requirement. This is to ensure you will be able to complete a total of 20 years of special retirement service by the time you reach the mandatory retirement age of 57. Applicants must provide proof of veterans' preference, land management eligibility, or prior creditable Federal service as listed in the announcement.
