On October 13th, 2008, the National Scholastic Aptitude Test(NSAT) was taken by 6th graders in elementary school, 3rd graders in middle school and 1st graders in high school. Before NSAT, some teachers in Seoul wrote a letter which contained worries about an influence on their educational space from NSAT. On test day, those teachers have been punished because they didn't obey an order as a national public officer.
