Also called: Criminal justice · Criminology and criminal justice · Criminal justice studies · Crime science
Updated How we use data
A criminology degree studies crime, why people commit it and how societies respond through policing, courts, prisons and prevention. It draws on sociology, psychology and law. Graduates work in policing, probation, social work, victim support, youth justice, policy and research, and some move into law or cybercrime investigation after further training.
Criminology graduates work across the justice system and in public services. Common directions include police officer or police staff roles, probation and prison work, youth justice and victim support. Some become social workers after an approved social work qualification, and others work as paralegals or go on to train as lawyers. Graduates with research skills become policy officers or crime analysts in government and charities. With extra technical training, some move into cybercrime investigation or cybersecurity.
Police officers protect the public, prevent and investigate crime, respond to emergencies and enforce the law.

In the UK, criminology is a popular three-year degree, often combined with psychology, sociology or law. In the United States, the more common degree is criminal justice, a four-year programme with a more practical focus on policing, courts and prisons. In many countries in continental Europe and elsewhere, criminology is mainly taught at master's level after a first degree in law, sociology or psychology. The degree is not a professional licence, and entry to policing, probation or social work follows each country's own training and selection rules.

A master's degree in criminology, criminal justice or security studies can help for research, policy and analyst roles. Some graduates go on to study law, through a graduate law degree as in the United States or a conversion course as in the UK. Others take a postgraduate qualification in social work or psychology. Police and probation services in many countries run their own training after selection. A PhD leads to university teaching and research.
Common jobs include police officer, probation officer, prison officer, youth justice worker, victim support worker, crime analyst and policy officer. With further qualifications, graduates become social workers, lawyers or cybersecurity specialists. Others work for charities, local government, courts, border and customs agencies, and research organisations. Many public service roles have their own selection and training.
Criminology focuses on why crime happens, how it is measured and how society reacts, drawing on sociology and psychology. Criminal justice focuses on how the system works in practice, such as policing, courts and prisons. In the United States, criminal justice degrees are more common, while in the UK criminology is the usual name. Many programmes cover both.
No. Most police services do not require a specific degree, and in many countries you can join after school and train at a police academy. Some countries run police training at degree level. A criminology degree can help you understand the work and prepare for selection, but it does not guarantee a place.
No. Criminology is a social science that studies crime, offenders, victims and justice systems. Forensic science is a laboratory science that analyses evidence such as DNA, fibres and drugs, and it usually needs a degree in chemistry, biology or forensic science. If you want to work in a crime laboratory, choose a science degree.
A sociology degree studies how societies work: how groups, institutions and cultures shape people's lives, and why inequality, crime, migration and social change happen.
A law degree teaches how legal systems work and how to find, interpret and apply the law, from contracts and crime to human rights.
A psychology degree is the scientific study of the mind and behaviour: how people think, feel, learn, develop and relate to each other.
