It is relevant to involve children and/or young people in your event if they are directly or indirectly affected by the subject concerned. When they are involved, you are responsible for them, and all organisers must adhere to the same principles, to minimum requirements for participation and, above all, protect and guarantee the safety of children under 18.
Map how the involvement of children and young people will enhance the event and lead to better or more relevant outcomes. Think about what they would get out of it and what they would add to your event.
If children and young people are affected by or are a target group for the event, they must be involved, e.g. participating in the actual event or drawing up the programme, speaking at it or being part of the audience. Be clear about what you expect and demand of them, and adapt your expectations to their prerequisites.
Focus on good and age-specific communication for children and young people before, during and after the event.
