What degree do you need to be an investigator?

In addition to education, criminal investigators seeking a position within local and state police departments often need previous experience in law enforcement. Professionals in this field typically become police officers first before working their way up to become criminal investigators.

Law enforcement training gives criminal investigators experience and insight into the investigative procedures and criminal law. Criminal investigators seeking work as private investigators do not need previous law enforcement experience, but many in this profession have it.

Licensure and certification requirements differ depending on an employee's state and type of investigation. Pursuing licensure or certification can improve skills and boost career options and salary potential. For example, criminal investigators considering careers as private detectives should look into earning a certification.

Criminal investigators who specialize in criminal defense investigation and negligence can pursue the certified legal investigator certification from the National Association of Legal Investigators. Additionally, all criminal investigators may pursue the professional certified investigator certification offered by the American Society of Industrial Security.

Criminal investigators in the police force go through the same training as police officers. These professionals enter the police academy and complete a training program, which typically takes six months. Police officers receive further on-the-job training once they enter the police force.

Training for this career includes lessons related to evidence collection, criminal and civil law, and investigative procedures. After becoming a criminal investigator, professionals typically receive additional on-the-job training in their new role.
