CJ-101: Introduction to Criminal Justice is an online criminal justice course that introduces students to the foundations, structure, and processes of the U.S. justice system. Using Introduction to Criminal Justice (18th Edition) by Siegel and Worrall, the course examines the nature and extent of crime, the development and enforcement of criminal law, and the functions of policing, courts, and corrections.
Students will explore how crime is measured and studied, the organization and responsibilities of policing agencies, and the constitutional protections that guide law enforcement practices. The course also covers trial procedures, sentencing, punishment, correctional institutions, and community-based alternatives. Contemporary issues—such as juvenile justice, restorative justice, and emerging crime trends—are analyzed to provide a modern perspective on the field.
By the end of the course, students will have a strong foundational understanding of the American criminal justice system and its real-world applications, making it a valuable starting point for those considering careers in law enforcement, corrections, or related public service fields.
