UNICEF has long recognized that there is great value in children’s sport and play, and has been a consistent proponent of these activities in its international development and child protection work. Health, educational achievement and social benefits are just some of the many desirable outcomes associated with organized physical activity. During recent years, however, it has become evident that sport is not always a safe space for children and that the same types of violence and abuse sometimes found in families and communities can also occur in sport and play programmes. The research presented in this publication shows a lack of data collection and knowledge about violence to children in sport, a need to develop the structures and systems for eliminating and preventing this form of violence, and that ethical guidelines and codes of conduct must be established and promoted as part of the prevention system. By addressing these gaps, significant improvements will be realized for the promotion and protection of the rights of children in sport.
