Conscription in North Korea occurs despite ambiguity concerning its legal status. Men are universally conscripted while women undergo selective conscription. Conscription takes place at age 17 and service ends at 30. Children of the political elites are exempt from conscription, as are people with bad songbun (ascribed social status in North Korea). Recruitment is done on the basis of annual targets drawn up by the Central Military Commission of the Workers' Party of Korea and implemented locally by schools. Conscription first began before the Korean War.
