Two English language teachers who were employed to mark university entrance exam papers told authorities yesterday that they had been asked to mark some papers again, allegedly so the students could acquire pass marks. The Education Ministry has asked for an internal investigation to be carried out following the allegations. The teachers, who have not been named, claim that they were approached by the head of the exam marking department in eastern Thessaloniki and asked to change the marks they had given on several papers. It appears that the teachers were also aware of the names of the students. The names of senior high school students are not visible on exam papers when they are passed to markers to ensure impartiality. Security is usually very tight for the competitive university entrance exams to ensure that there is no foul play but this year’s tests were already blighted when one set of exam questions was posted in Larissa before they appeared on the Education Ministry’s website.
