The American period in the Philippine educational system began in 1898 when American forces took control of the country from Spain. They sought to establish a universal public education system to promote democratic values and English was implemented as the medium of instruction. Key developments included establishing public primary and intermediate schools in 1901 and 1904, requiring provincial high schools in 1907, and founding the Philippine Normal School and University of the Philippines to train teachers. The focus was on citizenship, morality, and vocational skills through an American-influenced curriculum.
