Which is NOT one of the three main components of the U.S. criminal justice system?

• A. Education
• B. Courts
• C. Law enforcement
• D. Corrections

Answer: (A)

The concept being tested is the structure of the U.S. criminal justice system and its three main components. The three core parts are law enforcement, the courts, and corrections. Education is not one of these components, though it plays a role in crime prevention and rehabilitation; it sits outside the three-part framework. Law enforcement includes police and investigators who enforce laws and respond to incidents. The courts handle trials, determine guilt or innocence, and issue rulings. Corrections oversee punishment and rehabilitation, including prisons, probation, and parole. So, education isn’t part of the three main components.
