The teenagers will learn from former victims of bullying and experts in its prevention at a seminar run by the Anti-Bullying Ambassadors programme, which has around 5000 trained Ambassadors working in schools across the UK.
The Anti-Bullying Ambassadors Training Event has been organised by the Diana Awards and is being hosted tomorrow at Inverclyde Council's Port Glasgow High School at the new Port Glasgow Community Campus.
Education and Communities Convener Councillor Terry Loughran said: "The young people will creatively explore and understand the issue of bullying through interactive sessions.
"They will network with other passionate young people, exchange ideas and share good practice. This is all about gaining practical ideas and top tips and to come up with an action plan to stop bullying, prevent bullying from happening and to ensure everyone feels safe and happy in their school."
Programme manager Alex Holmes added: "As a former victim of bullying I know how isolated and unhappy a young person can feel when they are being targeted.
"The Anti-Bullying Ambassadors programme gives young people the confidence to stand together against bullies and support one another.
"We give Ambassadors the skills and tools to successfully spread the message - bullying will not be tolerated."
Port Glasgow High School head teacher Alan Dick said: "We are proud to host the training event in Inverclyde which will enable schools in Inverclyde and Glasgow to extend their effective anti-bullying programmes."
