Criminal justice is the study of all that's involved in criminal proceedings, including law enforcement, corrections, and courts. Students graduate prepared for careers as local, state, or federal law enforcement officers, corrections officers, private security agents, court service professionals, or even for graduate study in legal studies or law. With such interesting career prospects, it's probably not surprising to learn that criminal justice is one of the top 10 most popular majors chosen by student users on Cappex. Criminal justice students learn about the causes and effects of crime, how the criminal justice system works, and how to apply this knowledge to effectively deal with issues in the real world. Many programs feature classes that delve deeper to explore elements of corrections, criminology, security, justice administration, and forensic science. Many criminal justice programs are combined with or feature an available concentration in criminology, a closely related subject that studies the behavior of criminals, society, and criminal investigation and conviction. Students often have the opportunity to participate in internships with criminal justice agencies to gain valuable, firsthand experience in the field.Depending on their career goals, most criminal justice majors pursue an associate's or bachelor's degree; though there are career options available for those with only a high school diploma or GED. Those who intend to pursue a career in the field of law, such as a lawyer, would need three years of law school in addition to their undergraduate degree.
