Educational Requirements:

The initial step towards becoming a criminal investigator typically involves acquiring a high school diploma or equivalent. Many aspiring investigators then pursue a bachelor’s degree in criminal justice, forensics, or a related field. While not always required, a college degree can significantly enhance your knowledge base and competitiveness in the job market.

After being hired by a police department, recruits are usually sent to a police academy for formal training. Here, they learn essential skills such as self-defense, firearms training, emergency response, and the legal aspects of law enforcement.

Promotional Path to Criminal Investigation:

After serving as a police officer for a few years, officers can apply for a promotion to detective or criminal investigator positions. Promotions are usually based on performance, exams, and interviews.

Data on Wages and Job Growth:

However, wages can vary widely based on location, level of experience, and the specific sector (public or private) in which one works.

As for job growth, the BLS projected a slower than average growth rate for police and detectives at about 5% from 2019 to 2029. This rate might be subject to change based on the societal needs and governmental policies.

  2. Irregular Hours: Criminal investigators frequently work outside of typical 9-to-5 hours, including nights, weekends, and holidays.
