The Train-the-Trainer (TtT) programme equips trainers with the knowledge and skills necessary to deliver high-quality and culturally sensitive pilot trainings on domestic violence for diverse stakeholder groups across partner countries. Developed using advanced training methods and addressing clinical challenges faced by professionals, the TtT curricula are accompanied by a concise and practical Trainer-the-Trainer handbook. This handbook introduces the didactic concepts of the VIPROM curricula and is available in English, as well as translated versions in German, Italian, Swedish, and Greek, with a special adaptation for Austria.
