ADDLESTONE, GB / ACCESS Newswire / January 27, 2026 / Only one out of ten students who participated in the survey did not use ChatGPT for their final semester paper. Are plagiarism and AI misuse getting out of control? PlagiarismCheck.org spoke to teachers and students and compared statistical numbers over the years 2020-2025 to analyze the tendency.

According to the research, 10-25% is the average of the AI-generated content detected in the submitted texts in 2025 by the TraceGPT checker. In 2024, the number was higher, reaching 16,1-26,1%.

However, according to the teachers, the number of students relying on chatbots is growing. "At least 50% of grade 9 students and about 20% of the grade 10 students use AI heavily, then try to edit it to pass checkers, even with the warnings of a loss of 20% of the mark," says Ann Rayan after checking the final papers.

As for the plagiarism, the surveyed college educators found a significant improvement in students' papers after conducting the Originality and Writing Ethics workshop. Only 15% of the 2025 final works contained plagiarism as opposed to 80% before the class. Poor paraphrasing is named the number one reason for plagiarism occurrence in students' papers.

An average percentage of plagiarism found by PlagiarismCheck.org in submitted papers in 2025 was 8-21%. To compare, in 2024, this number ranged from 11% to 43%, and on average, from 15% to 25% from 2022 to 2023. Copying from each other has become the main plagiarism problem (54-70% of matches in 2025 as opposed to 30-51% in 2020-2022), followed by copying from online sources without proper attribution (20-40% in 2023-2025, compared to 40-65% in 2017-2023).

Plagiarism and AI misuse tendencies are not drastically increasing. However, they change along with the AI models and checkers, shifting the focus from "how much" to "in which way" the students work with the sources and AI chatbots.
