Wikipedia for Schools was collected by SOS Children's Villages. SOS Children believes education is an important part of a child's life. That's why we ensure they receive nursery care as well as high-quality primary and secondary education. When they leave school, we support the children in our care as they progress to vocational training or higher education. Sponsoring a child is a great way to help children who need your support.
