CCJS 100 Introduction to Criminal Justice is the University of Maryland Global Campus entry course on the three main parts of the system: law enforcement, courts and corrections.
UMGC's description sets three objectives: identify the components of the system, the practitioners within it and their role in forming and implementing policy, and the major theoretical tenets of criminal behavior.
Topics include community relations, the impact of criminal behavior and the importance of research in criminal justice. The course fulfills the general education requirement in behavioral and social sciences.
Students find it broad rather than deep. The skill being tested is seeing the system as connected, so a decision in one part has effects in the others.

Key Concepts Explained
How a Case Moves Through the System
A typical felony case passes through a sequence of decision points, each with its own practitioners and discretion.
Example: Police respond to a burglary, gather evidence and arrest a suspect. After booking, the suspect has an initial appearance where bail or release is set. A preliminary hearing or grand jury decides whether there is enough evidence. At arraignment the defendant pleads. Most cases end in a plea agreement rather than a trial. If convicted, the defendant is sentenced to probation, jail or prison, and may later be released on parole and supervised during reentry.
Crime Control Versus Due Process
Herbert Packer's two models describe a tension running through the system. The crime control model values speed and efficiency in suppressing crime. The due process model values fairness and protecting individual rights, accepting slower processing. Many policy debates are arguments about where to strike this balance.
Measuring Crime
The FBI collects crimes reported to police through its Uniform Crime Reporting program, now based on the National Incident-Based Reporting System (NIBRS). The National Crime Victimization Survey asks households about victimization, including crimes never reported. Comparing the two shows the "dark figure" of unreported crime and why research matters.
Community Relations and Policy
The description names community relations as a topic. Public trust affects whether people report crime, serve as witnesses and cooperate with investigations. Community policing tries to build that trust through partnerships, problem solving and officers who know their neighborhoods.
When writing about policy, show the chain of effects: a change in policing strategy affects arrests, which affects court caseloads and correctional populations. Support claims with research rather than assumptions.
Corrections and Reentry
Corrections is the largest part of the system by the number of people supervised, and most of them are on probation or parole rather than behind bars. Nearly everyone sent to prison eventually returns to the community, which is why reentry (housing, employment, treatment and supervision after release) is a growing focus of policy and research.
Papers on corrections are stronger when they weigh punishment goals: retribution, deterrence, incapacitation and rehabilitation.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Case flow analysis | System knowledge | Follow each decision point in order |
| Practitioner role paper | Roles and discretion | Describe duties, then discretion and its effects |
| Theory application | Explaining behavior | Choose one theory and apply it to a case |
| Discussion posts | Applying concepts | Cite readings and respond to peers with substance |
Where Students Get Stuck
- Treating parts separately. Show how police, courts and corrections affect one another.
- Opinion without evidence. Back claims with readings, data or research.
- Confusing jail and prison. Jails hold people awaiting trial or serving short sentences; prisons hold those serving longer sentences.
- Vague theory use. Name the theory and show exactly how it explains the behavior.
Study Tips for CCJS 100
- Draw the case flow as a diagram and add the practitioners at each stage.
- Use Bureau of Justice Statistics and FBI data for current figures in papers.
- Keep a glossary of system terms as you read.
- Follow a real local case in the news and match it to course concepts.

Frequently Asked Questions
The three components of the criminal justice system (law enforcement, courts and corrections), practitioners and policy, theories of criminal behavior, community relations and research.
Yes. UMGC lists it as fulfilling the general education requirement in behavioral and social sciences.
Three credits.
Crime control emphasizes efficient suppression of crime; due process emphasizes fairness and individual rights.
Plea bargaining saves time and resources for courts and offers defendants more predictable outcomes, so it resolves most cases.
