Criminal Justice Career Descriptions

Law enforcement encompasses many different professions, any of which can be attained by graduating from a good criminal justice school. This is a general summary of the different paths in criminal justice you may consider pursuing. As you might guess, each type of career has a different work environment and area of specialty.

Agents target illegal immigration, drug and weapons smuggling and terrorism.

Central Intelligence Agency (CIA): Notoriously secretive CIA agents gather foreign intelligence in order to aid in decisions on national security and foreign relations, including threats like nuclear weapons and illegal drugs. You don’t need a degree for clerical positions in this organization, but intelligence analysts and overseas agents often hold advanced degrees.

Crime Scene Investigation (CSI): Crime scene investigators gather evidence and perform analyses of crime scenes. Working with law enforcement, crime scene investigators find, package and send physical evidence to a lab for analysis, completing reports and testifying in court. Advanced knowledge of anatomy, physics and another science is helpful in this field, along with an education in criminal law and the legal process.

Criminologist: Criminologists, as their name suggests, study criminal behavior and laws, aiming to understand and explain the criminal mind in order to provide insight into the motivations and circumstances behind crimes and the effects that laws have on crime. Many criminologists conduct research as they teach at a college or university, and others are employed by federal and state agencies as advisors. Most criminologists have either a master’s degree or a PhD.

Detective: These non-uniform officers are accountable for in-depth investigation and fact-finding on legal cases. This is one of the most important areas of law enforcement, with detectives specializing in one field of the law, like homicide or narcotics. Detectives usually work on a case until an arrest is made, a conviction is reached or the case is dropped. Their duties can range from researching facts and witness background checks to surveilling suspects and participating in raids and arrests.
