Even With No CCTV in Exam Rooms... If AI Cheating Is Missed on the Spot, There’s Little That Can Be Done

[Financial News] The AI-assisted cheating by the top scorer on the tax accountant qualification exam came to light through the person’s confession, prompting calls to strengthen the system for monitoring national qualification exams, which relies on catching cheaters in the act and on confessions. As cheating methods using emerging technologies such as miniature cameras and generative AI become more varied, observers say a post-exam verification system is needed to objectively determine whether cheating occurred even after an exam has ended.
According to Financial News’ reporting on the 15th, the Human Resources Development Service of Korea could not review video footage of the classroom where A, the top scorer on the 63rd tax accountant qualification exam, sat the test because the room was not equipped with closed-circuit television (CCTV).
After allegations of cheating were raised, the agency checked the facts with the four supervisory committee members for A’s first- and second-round exams. They reportedly all said they had noticed nothing unusual. No irregularities were found during grading of the first-round exam, and an additional expert review of A’s essay answers for the second-round exam also failed to produce objective evidence proving cheating.
An agency official said in a phone interview with this newspaper on the 12th, “If cheating is discovered after the fact based on objective evidence, we can take measures commensurate with it under the rules,” but added, “It is not easy to launch an investigation based on suspicion alone.”
A admitted that day, through the YouTube channel of the lawyer handling the case, to cheating with electronic devices and generative AI on the first- and second-round tax accountant exams and the first-round certified public accountant exam. Rather than the AI smart glasses initially suspected, A reportedly used a miniature camera to photograph the exam questions and checked AI-generated answers on a smartphone and other devices.
The case has fueled calls to improve the effectiveness of post-exam verification as well as on-site monitoring. Statements from proctors and reviews of answer sheets alone make it difficult to determine whether cheating occurred; moreover, without CCTV inside the exam room, it is also difficult to establish after the fact whether electronic devices were used during the test.
In particular, the miniaturization of electronic devices and advances in generative AI are making it increasingly difficult to identify cheating using existing monitoring methods alone. This year, cheating involving smart glasses has also been caught repeatedly in national qualification exams, including the Fire Protection Systems Engineer and Information Processing Engineer exams.
The agency has pursued measures including the use of radio-frequency detectors and enhanced proctor training. During the National Assembly’s audit last October, it also announced plans to establish a dedicated proctor, the ‘AI Inspector,’ to identify AI glasses.
However, as cheating methods become increasingly varied, there are also calls for an additional verification system to ensure fairness in qualification exams.
Tax accountant Kang Shin-hyeong said, “Successful candidates should not be subjected to unfair inquiries or investigative procedures based solely on suspicion without clear evidence.” He added, “A separate verification exam that anyone who passed through the normal exam process could readily pass should be given to prevent, in advance, people who obtained qualifications through dishonest means from harming the public interest of taxpayers and tax authorities.”
Police, which received A’s letter of voluntary surrender, assigned the case to the Seoul Metropolitan Police Agency’s Metropolitan Investigation Unit and began an investigation. The Ministry of Finance and Economy also announced that day that it would promptly discuss ways to suspend the validity of A’s certificate confirming the passing result through the Tax Accountant Qualification Review Committee.
