Learning is fun and easy with Schools Wikipedia. SOS Childrens Villages 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. If you'd like to help, learn how to sponsor a child.
