Education in Indonesia was designed mainly to prepare Dutch children and the children of native elite for administrative tasks. In 1903 a primary school for Indonesian girls opened, and by 1940 a system of schools for native Indonesians existed alongside the elite Dutch system. Following independence in 1949, the new government tried to expand the educational system but was hampered by a lack of funds. In the late 1960s the government began promoting elementary education, which in Indonesia lasts for six years. Since 1990 compulsory education includes elementary schooling and three years of lower secondary schooling. An additional three years of upper secondary schooling are optional.
