The Ministry of Education, Science and Technology announced Thursday after a two-month investigation that it found 28 universities across the country falsely reported the employment rate for their graduates. According to the ministry’s investigation, a university in Gyeonggi Province manipulated the employment number by registering 63 unemployed graduates only on paper at 13 different firms.

The ministry has warned the 28 universities to correct the data and is also considering possible punishments for their misbehavior. Reports the Korea Herald.
