The WJEC Level 3 Applied Diploma/Extended Diploma in Criminology is particularly engaging because it blends theory with practical investigation. Rather than only learning ideas, you apply them to contemporary cases, data and debates. You develop skills that are valued in higher education and employment: research, analysis, report writing, evaluation, and confident communication. You also learn how to handle sensitive topics thoughtfully, consider ethical issues, and recognise how factors such as age, gender, ethnicity and social class can shape experiences of crime and justice.
Across the course you will study four units, each with a clear focus. Unit 1 explores changing awareness of crime: how crime is represented in the media, why some crimes attract public attention while others are overlooked, and how moral panics and stereotypes can influence public attitudes and policy. Unit 2 focuses on criminological theories: you examine different explanations of offending, from individual and psychological approaches to sociological ideas about inequality, labelling and social control, and you assess how well these theories explain real patterns of crime. Unit 3 looks at crime scene to courtroom: how crimes are investigated, how evidence is collected and interpreted, and how cases are built and processed through the criminal justice system. Unit 4 examines crime and punishment: the purpose of sentencing, the effectiveness of punishment and rehabilitation, and how society might reduce reoffending and support victims.
Assessment is split between controlled assessment and external exams. Units 1 and 3 are internally assessed through controlled assessment tasks completed under supervised conditions, where you produce structured, evidence-based work (for example, analysing crime campaigns, media products, case materials or investigation processes). Units 2 and 4 are externally assessed exams, testing your ability to apply criminological ideas, interpret scenarios and data, and construct well-reasoned responses under timed conditions. This balance suits students who want a mix of coursework-style depth and exam performance.
Entry requirements will be 5 GCSE grade 5 or above.
If you’re interested in careers such as policing, law, psychology, social work, youth justice, probation, the prison service, journalism or public policy, Criminology provides an excellent foundation. More importantly, it gives you a sharper lens on society: you will begin to notice how crime is defined, whose voices are heard, and how justice is shaped by power and politics. If you enjoy discussion, real-world issues and investigative thinking, Criminology is a subject that will challenge you and change how you see the world.
