The National Youth Service Corps (NYSC) is a program set up by the Nigerian government to involve Nigerian graduates in nation building and the development of the country. There is no military conscription in Nigeria, but since 1973 graduates of universities and later polytechnics have been required to take part in the National Youth Service Corps program for one year. This is known as national service year. Ahmadu Ali served as the first Director-General of the NYSC until 1975. The incumbent Director-General is Shuaibu Ibrahim.
