Career requirements for criminal investigators

In order to become a criminal investigator, the candidate needs to fulfill three main requirements:

  1. Have the necessary education
  2. Obtain the relevant experience
  3. Get promoted to the position

While the requirements of becoming a criminal investigator may vary between the different agencies, there are a few essentials that need to be met.

  • Education

Having the necessary education is the first step on the path of becoming a criminal investigator. Theoretically, a high school diploma or an equivalent may be sufficient with some agencies. Having a high school diploma means that you can start an entry-level position at a local or state law enforcement agency, usually as a police officer and then work your way to the desired position of a criminal investigator.

If you want to stand a better chance, however, it is good to invest a bit more into your education. An associate’s or bachelor’s degree are a great advantage and are sometimes even a requirement by the employers. A master’s degree in law enforcement or criminal justice can mean better pay and easier advancement on the career path.

Some of the appropriate majors for the position of a criminal investigator include criminal justice, law enforcement, homeland security, and computer science. You should be looking for programs that include courses in criminology, criminal law, investigative techniques, community-oriented policing, substance abuse and the like.

  • Experience

The second step in becoming a criminal investigator is gaining the necessary experience. The position is primarily assigned to officers with the following ranks: Law Enforcement Officer II, Law Enforcement Officer III, and Law Enforcement Manager II.

The career path starts at the level of a police officer/patrol officer. You should know that the hiring process is rather long and contains several steps. Generally, agencies require the candidate to be US citizen, 21 ears old, have a valid driver’s license and high school diploma or the equivalent. The candidates pass several tests – a written exam, physical ability test, psychological check and polygraph test. The background check is an important part of the process as it is important for the prospective police officers to have clean past with felonies, no serious misdemeanor, drug abuse, domestic violence and the like.

After serving for several years as a police officer, you can be promoted to the position of a criminal investigator. Some state and federal agencies hire entry-level criminal investigators without requiring any law enforcement experience.

Former military and law enforcement officers may meet the requirement for experience. Parole and probation officers are also allowed to use their experience in some states. Some agencies allow a bachelor’s degree in criminal justice to substitute the requirement for experience.

  • Get promoted

With the necessary education and experience you have the actual chance to get promoted to the position of a criminal investigator. It is good to show your superiors your intention of becoming a criminal investigator and work towards achieving it. Showing efficiency in the performance of the duties and tasks you are assigned with gives you better chances for career growth.

You can become a criminal investigator after finishing a probation period, taking a promotion exam or adding additional qualification, such as a degree in criminal justice or forensics.

Once you become a criminal investigator, you should be ready to undergo continuous training and testing in order to show that you keep up with the requirements and new trends of the job. Firearms proficiency testing and physical agility exams are performed at regular intervals.

Types of criminal investigators

Criminal investigators may specialize in a certain type of crimes. Often the specialization is determined by the needs of the agency or department they work for. There are several main “specialties” that include homicide, property crimes, human trafficking, narcotics, financial crimes, internet crimes against children, major crimes, violent crimes, etc. Often one crime may demand the work of criminal investigators from different branches.

Here are a few details about the most popular positions:

  • Homicide

This is investigation of cases that involved the death of a person when foul play is suspected. The criminal investigator usually works alone on one case but can also work in pairs. The investigator visits the crime scene to collect evidence, interviews suspects and witnesses, family and friends of the deceased. Work with other professionals is also included – for example with local prosecutors. Giving testimony in court is also part of the job responsibilities.

  • Cyber crimes

Criminal investigators working in this field usually have strong knowledge of computers and education in the field of computer sciences. Their tasks may include monitoring chat rooms to prevent crime against children or investigating cases of possible identity theft, internet-based scams or infringement of intellectual property.

  • Narcotics

Drugs are another major field of investigation and criminal investigators work at a local, state and federal level to cope with the problem. The sale and purchase of illegal narcotics is the main focus of the job. Quite often criminal investigators have to conduct undercover operations or infiltrate in drug trafficking groups. Giving testimony about the operations is part of their duties as well.

Salary and job outlook

The data of the Bureau of Labor Statistics reveals that the mean annual wage for the position of a criminal investigator is $83,320. The payment, however, varies depending on several major factors:

  • Location – there are some states that pay a much higher average salary compared to others. Some of the best-paying states are Alaska ($116,130), California ($103,810) and New Jersey ($100,980). Note, however, that these are not the states that employee the highest number of people in this position.

In other words, once becoming a criminal investigator you can develop your career both vertically – grow to a next level, or horizontally – move between departments and different positions (investing homicide, cybercrime, etc.).

What is the difference between detective and criminal investigator?

If you are browsing the job openings for law enforcement positions, you will come across open positions for detectives and criminal investigators. These, actually, are not different jobs. The difference in the name comes from the title the different agencies use for the position. Agencies that have uniformed positions such as police departments, sheriff’s departments, state patrol, have the job title of detective. Law Enforcement agencies that do not have uniformed positions such as FBI, Secret Service state divisions of criminal investigation and other federal agencies, use the title of Criminal Investigator or Special Agent.

In other words, the job duties of a detective or a criminal investigator are the same, along with the requirements for the candidates for these positions. Whether you will have the title of a detective or that of a criminal investigator depends solely on the agency you will work for.

If you have a passion for investigative work, ability to solve difficult cases and strong attention to details, then the job of a criminal investigator is the right for you. It is a good way to pursue a stable career in law enforcement and grow both horizontally and vertically within the system.
