After over 25 years with Devon and Cornwall Police and 12 years in the Armed Forces, David Ratcliff shares his front-line experience with the next generation as a public services lecturer at City College Plymouth.
“I decided to transition from policing to teaching at a college because I wanted to make a positive impact in a different way, by educating and inspiring future police officers,” David said. “After years in policing, I realised that sharing my real-world experience could help students better understand criminal justice and prepare them for the challenges ahead.”
David’s extensive service included time in the Targeted Policing Team, plain clothes operations and surveillance. As a Police Sergeant, he spent 15 years leading officers on the ground, overseeing performance, managing incidents and supporting the wellbeing of his team. Later, as a Police Inspector, he became the Critical Incident Manager for Cornwall and the Isles of Scilly.
“I was the first point of contact for significant incidents, managing the initial police response and ensuring appropriate resources were deployed. My role was to minimise harm, save lives and ensure a safe and effective police response.”

These experiences now inform his teaching style. “Real-world experience in policing significantly shapes the way I teach by bringing authenticity, relevance and practical insight to the classroom. I use real cases, scenarios and lessons learned from the field to help students connect theory to practice.”
His lessons cover both hard and soft skills – from operational command to emotional intelligence. “My time in police service has equipped me with valuable insights and skills that I bring into every lesson. I draw on real-life experiences to teach critical thinking, ethical decision-making and effective communication.”
David places particular importance on mental health and personal values. “The police is not a job but a way of life. Values, standards and mental health wellbeing are crucial within the police force. They form the foundation of ethical and effective policing.”
When asked what sets the College’s course apart, David pointed to the team’s lived experience. “The course offers access to lecturers with over 55 years of combined policing experience, covering a wide range of specialisms within the criminal justice system. Students gain first-hand experience of what it truly means to be a police officer.”
His advice for those considering a career in public service? “Go for it with commitment and curiosity and fully embrace the experience. Reflect on your own values, behaviours, mental resilience, and personal growth, as self-awareness is key.”
