An image to illustrate the Diploma of Higher Education in Criminology and Law
Crime, justice and the workings of the law affect us all and often dominate the news. This diploma takes a critical and analytical view of the role and functions of the legal system, and examines its relationship with crime, criminal behaviour and criminal justice. You’ll explore issues such as the law’s role in society, processes of criminalisation, violence and inequality, and their implications for justice. You'll gain the ability to critically assess everyday understandings of crime and criminal justice, as well as the social, political, and ethical dimensions of law, and understand the institutions behind criminal justice and legal systems.
A nationally recognised qualification in its own right, this diploma of higher education is also equivalent to the first two-thirds of the BA (Honours) Criminology and Law (Q92).
This criminology and law diploma has two stages, each comprising 120 credits.
At Stage 1, you’ll begin with a broad introduction to criminology, thinking about the ways in which the study of crime has been informed by a variety of disciplines. You'll also be introduced to key social problems and criminal justice responses. Next, you'll explore criminal law and the courts, looking at how the criminal law operates in real-life scenarios and how the English criminal justice system operates within the wider legal system.
