Criminology is the study of the criminal justice system, including how crime is defined and how offenders are processed. The level 3 Diploma course includes elements of internal assessment (controlled assessment) and external assessment (examination). Units 1 and 2 are taught and assessed in Year 12, including one piece of controlled assessment and one examination. Units 3 and 4 are taught and assessed in Year 13, again with one piece of controlled assessment and one examination. Topics covered include: changing awareness of crime, criminological theories, crime scene to courtroom and crime and punishment. Throughout the course, students gain an understanding of campaigns used within the criminal justice system, as well as how the criminal justice system works from a crime being committed through to prosecution.
