Technical Innovation Contests (Chosŏn'gŭl: 기술혁신경기; Hanja: 技術革新競技) is also the football league-system championship in North Korea. This championship is held in February, May and June.
Each North Korean football clubs are classified as 1st class (1급; 1級), 2nd class (2급; 2級) and 3rd class (3급; 3級).
Because of this and the general unwillingness of the North Korean football system to follow general world player transfer rules due to the political system of the country, the DPR Korea League winners are generally not eligible for any Asian Football Confederation club competition. Were they eligible they would be ranked for entry into the AFC President's Cup.
