There are an estimated 120–150 million children in street situations worldwide. These children have varied profiles and experiences and suffer trauma due to street violence, exclusion and separation from their families, among other things. To care for these children, social workers and their trainers need specific theoretical, practical and relational skills. These skills can be acquired through initial and continuing training and field experience. However, in most developing countries, few training courses exist for social workers caring for children in street situations.
