More than 50 police cadets will start serving communities in Preston from Wednesday.
The cadet scheme will provide the teenagers, who are aged 13 to 18, with the opportunity to develop their personal qualities and skills through a structured programme.
A total of 52 cadets - 27 juniors and 25 seniors - are being enrolled in the city.
Coordinator Sgt Helen Dixon said: “We hope the schemes will help us to better understand and build relationships with young people across Lancashire, provide a different kind of policing presence in towns and villages and encourage a greater sense of social responsibility.
“The cadets we have recruited are enthusiastic and keen to get stuck into the programme.
“We are looking forward to working with them and hope this will give them something positive to do as well as assisting them with their future career prospects.”
The cadets will wear a uniform and be expected to carry out volunteering work.
While on the course they will learn about the phonetic alphabet, DNA and fingerprints, fundraising, environmental and health projects, the history of the police and first aid. They will undertake a fitness test and take part in a mock trial.
Although they will not be able to go on independent patrols or have any legal powers, the scheme will give them a chance to express their feelings on policing issues and perform tasks including crime prevention initiatives, delivering leaflets and attending local events.
The schemes are based at colleges and schools, and are run by a combination of police officers, staff, special constables and support volunteers.
The cadets will spend up to two hours a week at college as well as additional time in their communities.
Lancashire Police and the Police and Crime Commissioner launched their Citizens in Policing programme earlier this year.
The programme focuses on the Special Constabulary, volunteer police cadets, police support volunteers, community volunteers and watch schemes.
It recognises the significant role these groups of volunteers can play in reassuring communities and increasing social responsibility, as well as providing new ways for the police to engage with communities.
Lancashire Police and Crime Commissioner Clive Grunshaw said: “I am delighted so many youngsters have embraced the opportunity to become cadets.
“Through being a cadet youngsters will get the chance to take on challenges, learn new skills and gain valuable experience.
“They will also play a vital role in engaging young people with the police service, and provide a different kind of policing presence across the county.
“Recruiting cadets is part of the wider Citizens in Policing programme and demonstrates our commitment to growing volunteering in Lancashire and ensuring we have volunteers who represent the residents and communities we serve.”
The recruitment window for the cadet schemes in other areas of the county will open for three weeks from September 20.
