Broker Who Arranged 75 Instances of TOPIK Exam Impersonation Gets Three Years

Case No. 2026Godan392, Seoul Central District Court, Criminal Division 12 (Single Judge Choi Hae-jin), Decided June 24, 2026

Factual Background

A, a Chinese national residing in Korea, had extensive experience taking the Test of Proficiency in Korean (TOPIK) and held the highest proficiency rating, Level 6. TOPIK measures Korean-language proficiency for overseas Koreans and foreign nationals and is widely used for university admission and employment purposes in Korea.

A was recruited through the messaging app WeChat by an upstream contact, B, who proposed a scheme to place impersonators into TOPIK exams in exchange for fees from clients. A agreed to participate.

A advertised on social media to recruit foreign nationals seeking to hire exam impersonators, then collected their personal information, including names, dates of birth, and photographs. A used a self-created automated macro program to handle exam registration and produced admission-ticket photos designed to make clients and impersonators appear similar. B, working from the personal information A supplied, produced forged identification documents to present to exam proctors and separately recruited the impersonators themselves.

Between December 2021 and October 2025, over a period of roughly four years, the two arranged for impersonators to sit for the TOPIK exam in place of the actual registered test-takers on 75 separate occasions. A was ultimately indicted for obstructing the official duties of a civil servant at the National Institute for International Education, the Ministry of Education body that administers TOPIK, through deceptive means (wigye gongmu jipaeng banghae).

Court’s Decision

Judge Choi found that A, acting in concert with B, had systematically and deliberately served as a broker connecting and managing TOPIK impersonation clients and impersonators over a period of several years. The court stated that this conduct not only obstructed the responsible official’s performance of duties but also seriously undermined the fairness that underpins the exam system, and found the offense grave given the sense of unfairness inflicted on the many test-takers who prepared honestly, and the resulting damage to public trust in the examination system.

The court specifically noted that A exploited a university and graduate-level background in computer science to analyze vulnerabilities in the exam registration system and personally build and deploy the macro program used to automate registration. The court also pointed to sophisticated methods used to evade identity-verification procedures, including the use of multiple accounts and exploitation of loopholes in the English-language transliteration of names on admission tickets.

The court further found that the scheme reflected extensive advance preparation rather than an impulsive act, noting that A recruited impersonators from China, covered their airfare and lodging to bring them into Korea, and even arranged a makeup artist to make impersonators resemble their clients more closely, all indicating a long-planned and repeatedly executed criminal scheme.

Judge Choi found that A appeared to have obtained substantial financial gain from the roughly four-year scheme. Regarding A’s refusal to submit transfer records from Chinese bank accounts that would have revealed the flow of funds, the court held that this refusal could be viewed as an attempt to exploit the limits of domestic investigative authority over foreign accounts in order to obstruct tracing of criminal proceeds, and that this was properly considered an aggravating factor in sentencing. The court also weighed evidence that, after the investigation began, A induced impersonators to give false statements and attempted to flee to China to avoid punishment.

Judge Choi concluded that, considering the nature and methods of the offense, its duration, the circumstances following the offense, A’s role and the scale of gains obtained, and sentencing standards in comparable cases, a severe sentence commensurate with the gravity of the offense was unavoidable.

Why This Matters

This sentencing decision signals that Korean courts are prepared to impose substantial prison terms in TOPIK impersonation and exam-fraud cases, particularly where the scheme is organized, technically sophisticated, and sustained over time. Practitioners advising clients in the education, immigration, or compliance space should note the court’s emphasis on several aggravating factors likely to recur in similar cases: technical exploitation of registration system vulnerabilities, use of forged identification, cross-border logistics indicating premeditation, and post-indictment obstruction such as evidence concealment or flight attempts. The court’s treatment of the defendant’s refusal to disclose foreign bank records as an aggravating sentencing factor is also notable, suggesting that defendants who rely on the jurisdictional limits of Korean investigators over overseas accounts to obscure proceeds should not expect that strategy to work in their favor at sentencing. For universities and employers relying on TOPIK scores for admission or hiring decisions, this case is a reminder of the scale and sophistication of impersonation networks operating against standardized testing systems.
