School of Investigation, Security and Defence

Learn the cutting-edge tools use in modern investigations

About the school
The School of Investigation, Security and Defence is here to help set you up in a career as a civilian within the police service or within the wider law enforcement family. We’ll teach you the skills you’ll need to start your career in policing, intelligence or criminal investigation, or how to advance your career if you’re already working in a related field.
We aim to make your learning as vocationally relevant as possible, helping you learn the skills you’ll need in real world contexts. For example, you’ll have the opportunity to explore areas such as the investigative process of law enforcement and forensic investigators on a journey from crime scene to court, or take on the role of an intelligence analyst, civilian detention officer, or civilian investigation officer to experience the investigative process as support staff.
We’ve embraced virtual reality and augmented reality to immerse the theoretical and practical aspects of the real-world investigative process and will be using Artificial Intelligence within the VR world to push the boundaries of online learning and to help you better experience the vocational roles involved from the crime scene through to the court room.
