Education in South Sudan is modelled after the educational system of the Republic of Sudan. Primary education consists of eight years, followed by four years of secondary education, and then four years of university instruction; the 8 + 4 + 4 system, in place since 1990. The primary language at all levels is English, as compared to the Republic of Sudan, where the language of instruction is Arabic.[1] There is a severe shortage of English teachers and English-speaking teachers in the scientific and technical fields.
