Police detectives, also called criminal investigators, are responsible for investigating crimes against persons such as homicides, robberies, burglaries, and assaults, as well as property crimes like fraud, arson, and vandalism. Detectives collect evidence, interview witnesses and victims, interrogate suspects, prepare search and arrest warrant requests, make arrests, and testify in court when necessary. The job is not as glamorous as many television programs would have one believe as most serious crimes are not solved in an hour.

Police Detective Experience Requirements

Police detectives must first work as a police officer, typically in the patrol division, in order to achieve the requisite skills and knowledge necessary to perform the job functions. Unlike uniformed officers, detectives typically wear regular clothing (or plainclothes) instead of uniforms and drive unmarked vehicles.

There are a number of types of detectives, depending upon their specialization: general, homicide, sex crimes, white-collar crimes, narcotics, fraud, burglary, and vice, for example. Oftentimes detectives spend a couple of years in one department before moving to another to broaden their knowledge base and experience and to prevent burnout. Detectives are also frequently assigned to specialized inter- and intra-agency task forces.

Police Detective Education Requirements

Virtually all police detectives begin their careers as patrol officers in order to achieve the requisite experience and knowledge prior to promotion. The general consensus among law enforcement agencies around the country is that patrol officers must work a minimum of two to three years in patrol before being eligible to test for detective, with some departments placing more stringent waiting requirements and other prerequisites upon their officers. More realistically, detectives typically have at least ten years of experience as a police officer in the field prior to promotion to detective.

Educational requirements include a bachelor has degree at the very least€”although some departments will accept an associate has degree€”with a master has degree preferred. Ideal majors include criminal justice, criminology, administration of justice, police science, crime analysis, and forensic science/criminalistics.

Police Detective Careers

Police Detective Salary

Generally, annual salaries for detectives range from $33,000 to $108,000 depending upon experience and geographical location, with the average salary $55,000 per year before various bonuses plus a number of exceptional benefits such as medical, dental, and vision insurance; paid holidays; paid vacation; sick leave; disability; and life insurance. Detectives in highly-specialized areas or members of particular task forces usually have a higher salary because of the specialized skills necessary to perform their job. 

Police Detective Career Outlook

Not unlike police officers, severe budgetary cuts plaguing many states, counties, and cities have resulted in cuts in law enforcement budgets and, therefore, job availability. According to the Bureau of Labor Statistics (BLS) the projected growth rate for police detectives through 2024 is a meager four percent despite steady increases in crime rates across the country.

Due to this low projection it becomes even more important for those desiring this job to ensure that they possess at least the minimum education and experience necessary. Not only will such qualifications improve one has chances of attaining the position but the additional experience and education provide necessary knowledge to increase one has chances of success.
