For criminal investigators, collecting evidence, interrogating suspects and reconstructing crimes is all in a day’s work. Learn how you can become a detective with your local police department or sheriff’s office today.

Often referred to as criminal investigators, police detectives work to investigate and solve felony crimes ranging from burglary and homicide to identity theft and fraud. Most often assigned to a specific interagency task force or unit, criminal investigators use their finely honed investigative skills to ensure perpetrators are brought to justice and victims are given closure.

Criminal investigators must be able to effectively conduct witness interviews and suspect interrogations, examine evidence, observe suspect activities, and serve as experts in courtroom proceedings. These unique skills and proficiencies are gained through extensive police experience, academy training; and in many instances, by earning a college degree.

1. Qualify for a Career in Law Enforcement

Becoming a detective starts by first becoming a police officer and serving in a conventional patrol capacity. It is during the training, probationary, and patrol periods that police officers gain an understanding and appreciation for the criminal process, the criminal justice system, and the role of the law enforcement community.

To become a police officer, candidates must first ensure they meet the minimum requirements set forth by the department or agency they’re interested in serving. Although these requirements differ from one police department to the next, typical requirements include:

  • Being a U.S. citizen
  • Being a resident of the state in which the department is located
  • Being at least 21 years old (or 21 by the time of Academy graduation)
  • Having no felony convictions
  • Having no misdemeanor domestic violence convictions
  • Possessing a high school diploma, college coursework, or a college degree

Many police departments require a college degree in a subject related to law enforcement or criminal justice. And just as many show they recognize the value of a degree by rewarding candidates with some level of college education. In fact, some municipal police departments have educational incentive programs in place to reward applicants who hold an associate’s, bachelor’s or master’s degree by offering an increase in the base salary at progressively higher percentages based on the level of the degree they hold.

As such, many candidates with their sights set on becoming a detective choose to complete a degree program with a major in subjects such as:

  • Criminal justice
  • Criminology
  • Justice administration
  • Sociology
  • Psychology
  • Forensic psychology
  • Police science
  • Crime scene investigations
  • Forensic science

2. Successfully Complete the Hiring and Training Process

The hiring and in-service training process is usually quite extensive, including everything from written exams and physical ability tests, to a thorough background investigation and psychological evaluation. The hiring process may take many months to complete.

Following the completion of the hiring process, new recruits are then required to attend a police academy, which can often be as long as 6-8 months. New police recruits with municipal police departments complete between 25 to 28 weeks of police academy training, during which time they are introduced to a comprehensive curriculum that includes:

  • Patrol procedures and tactics
  • Use of force
  • Crime scene investigations
  • Computer-based report writing
  • Interviewing procedures
  • Ethics
  • CPR and first aid

Getting Started in Your Law Enforcement Career

But there are many other types of detectives in police departments across the country, and they share many of the same knowledge, skills, abilities, and job descriptions with their colleagues in the homicide unit.

  • Domestic violence
  • Fraud
  • Juvenile crime
  • Missing persons
  • Narcotics
  • Organized crime
  • Robbery
  • Sexual assault
  • Vice

Education to Become a Homicide Detective

Since you’ll first need to be a police officer before becoming a detective, like all cops, you’ll need a high school diploma, or even an associate’s or bachelor’s degree for some of the higher ranks. Some law enforcement agencies may require additional training. At the very least, you’ll need to go through the police academy, which can last for six months or more.

At the police academy, you’ll learn about the following topics, and more:

  • Arrest and booking procedures
  • Driving techniques and practice
  • Firearms training, including marksmanship

A successful homicide detective career is built on a solid foundation of the right education and on-the-job training. While police officers only need a high school education to begin their career, those who aspire to the higher ranks in the police department may benefit from a college education. So, if you’re thinking of climbing the ranks, you should also consider that a degree in criminal justice may give you a leg up on the competition.
