Another issue is the high school equivalency examination, "daiken", that qualifies those who have not graduated from a regular high school to apply for a place in a state university and take an entrance exam. Until recently, only those who had completed compulsory education (i.e., up to junior high school) were entitled to take the "daiken"; this meant pupils of ethnic schools had to do extra courses before being allowed to take the exam. In 1999 the requirement was amended so that anyone over a certain age is qualified. Campaigners were not satisfied because this still meant graduates of non-Japanese high schools had to take the "daiken". In 2003, the Education Ministry removed the requirement to take the equivalency test from graduates of Chinese schools, Mindan-run Korean schools and international schools affiliated with Western nations and accredited by American and British organisations. However, this did not apply to graduates of Chongryon schools, saying it could not approve their curricula. The decision was left up to individual universities, 70% of which allowed Chongryon school graduates to apply directly.
