The work is about the role of children's groups in promoting the children rights in Rwanda, from 2014-2015. The rights of the child are not only a concern of the United Nations though, the African continent is also committed to promoting the Rights of the Child in Africa. Therefore, the African Union, in 1989, adopted the African Charter on the Rights and Welfare of the Child, which went into effect in 1999 (OAU, 1981). The study analyzed the extent to which Children's Voice contributes to the promotion of children rights in Nyakabanda Sector.
