This Manual is a journey towards participation of school student at different stages, from a very grassroots involvement to formally established organisation on a national and international level. It will lead you through the path and the universe of school student participation with the aim of encouraging you and your peers to be active members of the school community. In each chapter you will find useful tips on different topics, from the definition of a stakeholder to suggestion on how to run a democratic organisation; from communication to how to organise small and big events; passing through how to advocate and carry out negotiations on how to have your rights protected and enlarged.
