How Much Do Criminal Justice Jobs Pay?

The number of jobs in criminal justice is growing faster than those in other careers and the high demand is translating to increased salaries. Some areas are also hiring more than others, such as Washington, D.C., New York, Delaware, Florida, and Virginia, and the higher cost-of-living in these areas is also driving pay up. Take a closer look at national salary trends for various types of legal and criminal justice jobs:

Deciding if the Criminal Justice Field Is Right for You

Because of the breadth of the criminal justice field, it's difficult to nail down specific traits or preferences that are common to people that choose this profession. However, most positions fall into one of two general categories—law enforcement and the legal process—and individuals in each often share certain strengths.

  • Law Enforcement
    Most people in this field thrive on interacting with others, even in the stressful situations faced by law enforcement officers. They usually have sound judgment and good decision-making skills. In addition, law enforcement officers must be persuasive communicators, skilled at gaining control of situations that are sometimes unpredictable or volatile.

  • Legal
    In the legal arena, patience and persistence are the hallmarks of professionals who must deal with numerous people, from criminals to law enforcement officers to the many people who hold specialized jobs in investigative or judiciary capacities. These individuals are resourceful, with good research skills, and are able to apply logic to any number of situations or problems in order to "connect the dots" in facts surrounding a case.

Skills for Success in Criminal Justice

Criminal justice and legal professionals need a host of interpersonal and management skills, as well as expert knowledge and specific skill sets for certain specialty areas. They must also be well-versed in the tools that are relevant to the career, which can vary from firearms to advanced software for tracking crime data. Below are some of the common skills and technologies used in criminal justice:




Because so many criminal justice roles depend on the use of evidence, it's important to be able to organize evidence and facts into a logical order or sequence and to maintain a chain of custody to prevent tampering. In other capacities, keeping track of caseloads, coordinating team efforts, and recording documents also requires strong organizational skills.



Extracting information from people, especially those who may be reluctant to give details, is a critical skill. Interviewers must be comfortable talking to a wide range of people and know the right questions to ask in order to get the information needed.



Criminal justice professionals do a lot of thinking on their feet—often in undesirable circumstances. Professionals who are responsible for people's lives and livelihoods—even in non-emergency situations—must be able to make logical, even-handed decisions.



Verbal and written skills are critical across the gamut of the criminal justice career field. Most jobs require written reports, so it's vital to create clear, accurate written accounts of events.

Tools / Technology


Computers and electronics

Most criminal justice jobs require the use of computers and other electronic equipment, such as body cameras. It's also routine for criminal justice professionals to use informational databases such as the Integrated Automated Fingerprint Identification System (IAFIS) or the National Crime Information Center (NCIC).



Individuals in direct law enforcement usually carry a sidearm and also know how to use other types of firearms such as shotguns and Tasers.


Communication equipment

Two-way radios link first responders to supervisors and backup assistance. Law enforcement officers also depend on the electronic communication of visual information such as photos of evidence.

Postsecondary Education Options

Various levels of postsecondary education options exist in the criminal justice field. In general, education is sequential, so students may start with a two-year associate degree - or four-year bachelor's degree - and then continue to work their way up the educational ladder as it suits their career goals. While it can easily take a decade to reach the doctoral level, criminal justice professionals are on the job long before that, building on their education gradually while simultaneously gaining on-the-job experience. Potential degree options within criminal justice are discussed below to give you an idea of what to expect during your academic journey.


While certificates are not educational end goals in criminal justice, they are good options for providing the needed boost within a career or to make a career change. Some can serve as a launchpad to go on to obtain a bachelor's degree, while others are aimed at giving students knowledge in a specific area to improve their credentials and make them more marketable. Certificate programs usually require about 15 credit hours and include courses in criminology, victimology, forensic psychology, and police and court procedures.

Specializations and Employment Settings

Due to the depth and breadth of the criminal justice field, there are numerous specializations within it. These specialty areas usually corresponding to the type of workplace and/or employer. Professionals may work for government agencies at the local, state or federal level as law enforcement officers or support staff; in corrections facilities dealing with incarcerated criminals; or in any number of investigative or social work roles, both in the public or private sectors.

While some jobs—such as standard police patrols—have been around for centuries, the rise of computer technology and improvements in areas such as forensic science have created many new specialties. Take a look at some of the major areas:

  • Corrections
    One area of specialization within the criminal justice field is corrections. Most of these positions are found within a private or public jail or prison. However, a probation officer—tasked with monitoring the activities of released inmates—may be headquartered at an office building for a government agency, as well as spend significant time in the field.

  • Cybercrime
    A growing area of specialization is cybercrime, a combination of computer science and criminal justice. In fact, through 2028, the Bureau of Labor Statistics predicts a 32 percent increase in jobs for information security analysts, who specialize in investigating and protecting against cybercrimes committed via the Internet or other with other computer technologies. These professionals are experts in computer forensic investigative techniques and are able to trace criminal activity based on electronic footprints. They may work for private companies as security experts, for public agencies such as the Department of Homeland Security, or for the cybercrime division of the FBI.

  • Forensic science
    Forensic science is about collecting and analyzing evidence. Professionals in this specialty may be called to crime scenes to search for and gather evidence and may spend time in laboratory settings to examine and analyze the collected evidence. Employment in the specialty field is growing rapidly, with the Bureau of Labor Statistics predicting 14 percent growth through 2028.

Exams, Certifications, and Credentials

Many criminal justice specialties have exams or certifications that are either required for employment or can significantly enhance the chance of being hired. Certifications demonstrate that professionals have acquired specific competencies within a given area and demonstrate a commitment to the field. Following are some of the certification options within criminal justice:

  • Criminal Justice Awareness and Terminology
  • Certified Criminal Justice Professional (for work with drug offenders)
  • Certified Legal Assistant (for paralegals)
  • Professional Peace Officer

Requirements vary by certification but may include significant additional training. For example, the Certified Criminal Justice Addiction Professional (CCJP) credential usually requires several hundred hours of addiction education and participation in a supervised practicum, as well as passing an exam.

Other careers may require examinations as well. Most states require private investigators to pass an exam demonstrating basic knowledge of the criminal justice system, including legal and ethical considerations. Police officers also take an entrance exam before entering police academy training.
