Wikipedia for Schools is one of SOS Children's Villages' many educational projects. 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. Would you like to sponsor a child?
