It is unusual for a school to have glass windows. Weavers in the community wove and sold belts to pay for the window glass so that their children can stay dry and warm while they study.
About one thousand students attend the school now, from Chinchero and outlying communities.
Children enter first grade at eight years old speaking Quechua, the Inca language they learned at home. But teachers in school speak Spanish. Therefore most children and many of their parents become bilingual; they speak both Quechua and Spanish.
In South America approximately eight to ten million people today speak Quechua, the language of the Inca empire.
