Home Criminologist


Criminology is the study of crime from a societal perspective. Criminologists investigate why crimes are committed, who is committing them, what type of societal factors might be contributing to higher crime rates, and the best ways to predict, deter, and prevent future crimes.

While many criminology graduates might eventually enter the field of criminal justice, there is a distinct difference between the two disciplines. Criminology focuses on the things that lead to individuals committing crimes or acting in a criminal way, whereas criminal justice focuses primarily on the individuals who commit the crime.

Whether you want to help reduce crime rates, participate in criminal justice reform, prevent crime from happening, or ensure a higher quality of life, the study of criminology can make a real difference to people’s lives.

What Does a Criminologist Do?

At a basic level, criminologists focus on two things: studying and analyzing data.

Typical Duties

  • Conducting research: Criminologists conduct research, using data to analyze crime patterns that could lead to preventing and deterring future crimes. Criminology data ranges from specific behavioral and biological profiles of those who commit crimes to geographical crime data.
  • Developing theories: In order to effectively translate data into action, criminologists develop theories based on the research they conduct. These theories help others in the field understand crime patterns and improve their practices.
  • Compiling and generating reports on crime statistics: While the research, data collection, and analysis are the first steps to be taken, criminologists must also take the information learned and create a report that is helpful to the audience. Reports might be created for colleagues, superiors, or even the general public.
  • Investigating crimes and crime scenes: In many cases, criminologists will also work with data on a smaller scale, such as through individual crimes. In these cases, they won’t be working with large data sets, but rather with pieces of evidence from a crime scene or larger-scale crimes.
  • Evaluating, analyzing, developing, and implementing criminal justice policies and procedures: Many who choose the public policy path utilize the research and data analysis skills described above, while also looking directly at specific policies and conducting research and analysis on how those policies affect crime.
  • Program implementation: Criminologists also utilize their research and reports to implement programming that is appropriate for a specific population or geographic region. Those who carry out those recommendations must be systems thinkers, able to take action on a recommendation that came from a more theoretical standpoint.

Common Career Paths

There are many opportunities for criminologists to branch out and specialize in areas within the field. For example, criminologists can specialize in topics such as specific age groups, demographics, geographical areas, or types of crime.

Beyond looking at specific communities, a variety of career paths are available to criminologists, including:

  • Corrections
  • Law enforcement
  • Criminal investigation for federal and state agencies
  • Forensics
  • Judicial
  • Counseling
  • Medical investigation
  • Private investigation
  • Teaching
  • Other careers in sociology

How to Become a Criminologist

In order to become a successful criminologist, you’ll need to complete the following steps:

  • 1Earn Your Degree
    Getting a bachelor’s degree in sociology, psychology, criminology, or criminal justice can open the door to entry-level jobs in criminology. However, many employers may now require a graduate degree in those same fields – research the type of job you’d like to pursue before choosing which path to take.
  • 2Get an Internship
    Snag an internship with a police department, law office, state or federal government office, a community organization involved with the justice system, or a group that conducts research on relevant subjects.
  • 3Obtain a License
    Many states and law enforcement agencies require criminologists to pass a licensing exam before they can begin their career.
  • 4Pursue a Criminologist Position
    Jobs can be found within the FBI, ATF, at other federal, state, or local agencies, at police departments, in consulting agencies, and even at colleges and universities. (Note – not all positions will have the term “criminologist” in the title.)
  • 5Join a Professional Association
    Join an association such as the American Society of Criminology, the International Society of Criminology, the Law and Society Association, or other groups serving the field of criminology.
  • 6Stay on Top of Current Events
    Stay current with what’s happening in the field. Attending conferences to network and learn about new developments will not only allow you to build relevant contacts but also keep your knowledge of the subject up to date, too.
  • 7Get an Advanced Degree
    People interested in becoming criminologists often pursue a master’s or doctorate degree. An advanced degree can provide the opportunity for greater responsibilities and a higher salary.
  • 8Become a Sub-Field Expert
    Find a sub-field in criminology to master. This will help you gain recognition, advance your career, and enjoy greater workplace opportunities.

Degree Programs in Criminology

While some associate degrees will provide entry into service positions within criminal justice, a bachelor’s degree or higher is often necessary to advance in the field of criminology. Criminology degree programs teach you to think critically and manage the ever-evolving nature of technology and data in the field.

Bachelor’s Degree

A full-time bachelor’s degree in criminology can take at least four years to complete. However, if you already have an associate degree, a bachelor’s completion program focused solely on the criminology major could take as little as two years.

All bachelor’s programs require the completion of general education credits and criminology-specific major requirements. The study is multidisciplinary, with coursework covering areas such as psychology, sociology, statistics, data analysis, history, and public policy.

With a bachelor’s degree in criminology, you’ll be prepared to enter and develop a career across a variety of fields such as human and social services, public policy, juvenile justice, and forensics, as well as direct service positions such as security, probation, and police officers.

Master’s Degree

A master’s degree in criminology will help you develop the technical skills necessary to advance in the criminology field, alongside the critical and analytical practice needed to progress to management-level positions. A full-time master’s program typically takes two years to complete.

Each program offers something unique, but all are largely multidisciplinary. Many master’s programs are more generally focused, allowing students to hone their interests throughout the program. Some also offer specialization opportunities in topics such as forensics or cybersecurity. Programs often range from more theoretical courses, such as comparative studies in criminal justice or foundations in criminology, to skills-based courses, such as those dealing with statistics or computer applications in criminal justice. Many programs require at least 30 credit hours of coursework as well as either a master’s thesis or a practicum as a culminating project.

Doctorate Degree

If you want to participate in the advancement of research in the field of criminology, a doctorate is essential. While many positions for a Ph.D. in criminology are based within higher education research institutions, there is an increasingly large number of criminologists now working in the private sector and the government.

Doctoral program completion varies widely and depends on the level of education you have upon entering. It requires strong self-determination and time management skills. Programs can take as little as four years but will often take five or more. The coursework involved is often similar to that of master’s level courses but may require that more classes are taken. In some programs, the Ph.D. track can also include completing a master’s degree along the way.

The most rigorous and variable part of the doctorate is the final dissertation, which is a multi-step process. It can take at least a year to complete and will involve proposals, proposal defense, data collection, various draft reviews, and dissertation defense.

Online Programs

Many master’s (and increasingly more bachelor’s) degree programs now offer online coursework. An online program is a great option if you’re already working in the criminal justice field, as you’re able to apply your coursework directly to your job. An online program can also have a huge advantage in flexibility and pacing. Additionally, it’s typically less expensive in the long run to complete your degree online, because you’re not spending your money on transportation or moving costs.

While online coursework has many advantages, it does also have its negatives. These can include spending less face-to-face time with students and faculty, and the challenges met when trying to gain hands-on experience in the field. However, online programs are increasingly finding ways to develop strong, cohesive communities as well as providing alternative ways for students to apply their coursework in the real world.
