A background to Schools Wikipedia

Schools Wikipedia was launched to make learning available to everyone. 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. Find out how you can help children in other countries.
