At Tuusula high school in Finland, a principal has made the controversial decision to dismiss a student's results from all autumn 2025 matriculation exams due to suspicions of cheating. The allegations arose during the preliminary grading of a mathematics exam when an evaluator noted that the student's answers exhibited characteristics atypical of human responses, suggesting they resembled those produced by artificial intelligence. This raised enough concern for the school to take decisive action against the student despite no direct observations of cheating during the exam itself.

The specific question in question was highlighted by the Matriculation Examination Board, which indicated that the student's response appeared to be based on a pre-written answer rather than independent calculation. The student had submitted their answers quickly and did not use auxiliary tools or scratch paper, which further fueled the principal's belief that the answer was produced without any legitimate academic effort. While the exam was conducted without incident and the student did not leave the testing room at any time, the principal concluded that cheating was the only plausible explanation for the suspiciously composed response.

This decision has sparked a debate over the evidentiary standards required for academic integrity violations, as the absence of direct evidence of cheating may challenge the fairness of the principal's ruling. Critics argue that relying solely on the style of answers that mimic AI could set a worrying precedent in academic evaluation. It raises significant questions about the balance between maintaining integrity in exams and the rights of students accused without solid proof of wrongdoing.
