Red Flag Mangyongdae Revolutionary School is an elite public secondary school in the Mangyongdae district of Pyongyang city, North Korea. Established in 1947, it is a special education school with access only to the Workers' Party of Korea, Korean People's Army, administrative and high-ranking officials’ families. As of 2012, Mankyongdae School was one of three schools, alongside the Kang Pan-sok Institute and Namsan Senior High School, which serve families with very high Songbun rankings. No wavering or hostile class children and very few children of high songbun, outside of the three “lines”, are allowed to attend these schools, and special schools like these do not exist outside of Pyongyang.
