Authorities in Andong, North Gyeongsang Province, South Korea, have uncovered a shocking case involving the illegal leaking of exam papers at a local high school. A former temporary substitute teacher, in collusion with a student’s parent and a school administrator, allegedly broke into the school multiple times to steal test questions.
According to reports, the trio attempted another break-in in the early hours of July 4, triggering the school’s alarm system and leading to the discovery of the operation. CCTV footage later revealed that similar intrusions had occurred at least five times over the past year.
Police confirmed that the 30-something substitute teacher, referred to as C, had been privately tutoring the student—a practice banned in South Korea for public school teachers. Despite no longer teaching at the school, C allegedly returned to assist the student by illegally accessing exam materials. The student’s parent, A, and a school administrative staff member, B, are accused of aiding the break-ins.
All three adults have been arrested, with courts citing concerns over evidence tampering and flight risk. The student involved faces expulsion, pending final approval from the provincial education office, and has had the subject score nullified.
Authorities are now investigating how widely the exam questions may have been leaked and whether other students or staff were involved.
