A plan by the education ministry to allow graduates of Western-style schools to skip the preadmission tests for national university entrance exams may be expanded to include graduates of ethnic Asian schools, education minister Atsuko Toyama said Friday.

Officials of the Education, Culture, Sports, Science and Technology Ministry announced Thursday they have put on hold a plan announced March 6 to allow graduates of 16 international schools accredited by Western education groups to bypass the "daiken" preadmission exams.

The plan was widely criticized for discriminating against non-Japanese schools in which classes are not taught in English, such as those for ethnic Korean children.
