This document is part of a toolkit written for and by HIV trainers. It has been designed to help trainers plan and organise educational sessions with community leaders or organised groups. The toolkit consists in a collection of participatory training exercises to help people at all levels understand stigma - what it means, why it is an important issue, what its root causes are - and develop strategies to challenge stigma and discrimination. The present document contains the Module J "Young people and stigma". This module is designed to be used mainly with young people who face stigma themselves. The exercises help them identify the particular stigma issues that they face; to analyse the causes and consequences of stigma; to address the link between stigma, gender and sexuality; and also to empower them with skills to cope with stigma and build strategies for change.
