Pupils from Pope Paul Catholic Primary School in Potters Bar held a celebration this week, to mark the completion of the Mini Police programme.
The programme is a fun and interactive volunteering opportunity for children aged nine to 11.
Officers visit local primary schools to deliver the programme over several weeks, covering topics such as road safety, personal safety, staying safe online and anti-social behaviour.
It aims to build trust with local communities, promote responsible citizenship and help young people establish an interest and understanding in policing and community safety.
To recognise their hard work, pupils were presented with certificates by Hertsmere Chief Inspector Mark Bilsdon during a special ceremony in front of their parents.
The children were then able to have photos taken with police vehicles, while parents chatted with officers from the Safer Neighbourhood Team.
PCSO Cheryll Lavell, who led the programme at the school, said: “The Mini Police scheme enables us to engage directly with younger members of the community to make sure they know the police are there to help them, should they ever need it.
“It also teaches them some valuable skills as well as how to keep themselves safe.
“The children were really enthusiastic throughout and it was an absolute pleasure to teach them. Hopefully we’ve inspired some future new recruits!”
