4 members of the South Korean Teachers Union (KTU) have been sacked for refusing to adminster standardised tests The four refused to administer the tests to their primary school pupils in the Gangwon province of Korea for professional reasons. Leaders of the KTU are quoted in the Hankyoreh as saying: "Tests aimed at standardization have the effect of lining up schools and students in systems of ranking, and have the negative effect of encouraging excessive competition for university entrance and the extracurricular tutoring craze." The previous system had been one of sampling which had allowed teachers to use their professional judgement as to when and whether to administer the tests. The chair of the Gangwon branch of the KTU has gone on hunger strike in front of the provincial education offices to demand the reinstatement of the four teachers.
