Unlike the previous educational system of the regional Southern Sudan—which was modelled after the system used in the Republic of Sudan since 1990, the current educational system of the Republic of South Sudan follows the 8 + 4 + 4 system (similar to Kenya). Primary education consists of eight years, followed by four years of secondary education, and then four years of university instruction.
The primary language at all levels is English, as compared to the Republic of Sudan, where the language of instruction is Arabic. In 2007 South Sudan adopted English as the official language of communication. There is a severe shortage of English teachers and English-speaking teachers in the scientific and technical fields.
