Training of Trainers Manual providing a comprehensive training programme that can be used by ‘master’ level peer educators and trainers. The manual uses participatory techniques based on a variety of theoretical frameworks to ensure that future trainers of peer educators are skilled and confident in their abilities to train peer educators and serve as informed resources for their peers. It also explains how the work of peer educators fits within a systematic approach to behaviour change on individual and societal levels. Special attention is given to gender and cultural sensitivity and to youth participation in health.
