In 1998, there were 400,325 Namibian students in primary school and 115,237 students in secondary schools. The pupil-teacher ratio in 1999 was estimated at 32:1, with about 8% of the GDP being spent on education. Curriculum development, educational research, and professional development of teachers is centrally organised by the National Institute for Educational Development (NIED) in Okahandja. 

Namibia (i/nəˈmɪbiə/, /næˈ-/), officially the Republic of Namibia (German: Republik Namibia (help·info); Afrikaans: Republiek van Namibië) is a country in southern Africa whose western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although it does not border Zimbabwe, a part of less than 200 metres of the Zambezi River (essentially a small bulge in Botswana to achieve a Botswana/Zambia micro-border) separates it from that country. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek, and it is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU), and the Commonwealth of Nations.
