The Latin American international Teacher's Day is on September 11, commemorating the death of Domingo Faustino Sarmiento, an Argentinian politician and respected educator. This establishment was agreed on during 1943's Interamerican Conference on Education, held in Panama.

Many Latin American countries, however, have a separate national Teacher's Day better accorded with their own history. In Brazil, Teacher's Day is October 15. In Mexico, in September of 1917, the Federal Congress decreed May 15 as Teacher's Day. May 15, 1918 was the first celebration of this holiday in Mexico.
