The Education Ministry announced that 81.2% of public schools in Japan expressed interest in participating in the nation-wide academic achievement test. The test will be administered to 6th and 9th graders on April 17. The national academic achievement test had not been administered for 43 years, from 1966 to 2008. However, since its reintroduction in 2009, the participation rate has been gradually increasing.
