Usher Renu Olivera Sanca, 7, is a first grade student at Ponta Nova Unified School, in the village of Ponta Nova, Oio Region, Guinea Bissau. Born with a physical disability, Usher would almost certainly have joined the 90 per cent of disabled children in developing countries worldwide who are out of school, were it not for his proximity to a UNICEF-supported child friendly school.
