Dec 2023 to Mar 2024United StatesGrammarly (reported)
In late 2023 a junior at a public high school in Hingham, Massachusetts, and a classmate submitted a script for an AP U.S. History project that, a federal court later found on a preliminary record, contained text copied from Grammarly, a publicly available AI tool, including citations to nonexistent books, with no acknowledgement of AI use. Turnitin and other AI detection tools had flagged the script, and a school official says the pupil admitted using Grammarly. In December 2023 the school treated it as cheating: the pupil failed two parts of the project, served a Saturday detention and was rejected from the National Honor Society in spring 2024, though he was later admitted. His parents sued, arguing the school had not made its AI rules clear; on 20 November 2024 the US District Court for the District of Massachusetts refused a preliminary injunction to undo the penalties, and in February 2025 the parties dismissed the case with prejudice.

2024AustraliaTurnitin AI-text detector
The ABC reported on 9 October 2025 that Australian Catholic University (ACU) registered nearly 6,000 cases of alleged academic misconduct across its nine campuses in 2024, according to internal documents, and that about 90 per cent of the referrals related to AI use. The ABC reports that the university's case against a final-year paramedic student hinged on a single AI-generated report that, the student said, marked 84 per cent of an essay as AI-written; the student produced dozens of pages of evidence and the ABC describes the student as wrongly accused. Students the ABC spoke to said they were notified at the end of semester, had little time to respond and waited months to be cleared, and the ABC saw emails asking students for handwritten notes and internet search histories. A final-year nursing student was cleared after six months, during which her transcript read 'results withheld'; she believes this cost her a graduate position, and the report does not say what evidence prompted her referral. The ABC says internal documents show ACU knew of problems with the detector for more than a year before abandoning the Turnitin tool in March. ACU's deputy vice-chancellor called the figures substantially overstated, said cases resting solely on Turnitin's AI detection were dismissed immediately, acknowledged investigations were not always timely and said the university regretted the impact on some students.

Event date unknownUnited StatesTurnitin AI-text detector (reported)
The University Press, Florida Atlantic University's student newspaper, reported on 29 September 2026 the accounts of two students who say they were penalised over AI-detection flags. A computer science sophomore submitted a paper 'last year' and received a zero after the professor flagged it for AI use after applying it to Turnitin; after the student emailed the professor, the grade was improved. The student says that when they ran the paper through a detector, it said the writing was overly human-sounding. A senior sociology major was accused of using AI on an essay and received a zero with little communication from the professor; after the student emailed to say no AI was used, the professor waived the penalty and gave a 50. The newspaper describes the second student's grade as due to a false AI detection and does not name the tool in that case. No professor's or university account of either case is reported.

30 Sept 2026 to 1 Oct 2026Event location unknownTurnitin AI-text detector (reported)
In a public post to r/ApplyingToCollege early on 1 October 2026 (UTC), a student taking the Advanced Placement (AP) Research course writes that their teacher told them that day that their source annotations had been found to be '100% ai' by Turnitin. The student says they did not use AI. They say their document history shows them typing over the course of an hour and that some sentences closely follow notes they wrote for an earlier assignment. They also say they had faced no AI accusation in a research course with the same teacher the year before. By the student's account, the teacher said the matter would be discussed later and that Turnitin's AI checker feedback never ends up being a false accusation. The student says the accusation leaves them upset and unsure how to defend themselves. No grade or disciplinary outcome is reported. The account is uncorroborated, and one commenter doubted it.

Nov 2023VietnamUnidentified AI writing tool and Turnitin (reported)
In November 2023 a student at the Ho Chi Minh City University of Foreign Languages and Information Technology (HUFLIT) wrote on the university's anonymous confessions page that a writing-course essay had been returned with 50 percent of the marks deducted because the lecturer found it had been written with AI. The student said the lecturer had warned that AI-written essays would be treated as plagiarism if detected, had not expected detection, and learned from the lecturer that Vietnamese-to-English translation software could also be counted as AI use when checked with specialised plagiarism software; the student did not know whether the course could still be passed. The vice-rector told Tuoi Tre that the lecturer had told students before the assignment not to use AI applications, that the course tests independent writing, that using an AI support tool breached academic-integrity rules, and that the deduction was appropriate, while noting the university had no formal document on sanctions for AI use. A university representative told Thanh Nien and Dan Tri that the university does not ban AI but requires transparency about tools used, uses paid AI-detection services when necessary, and had not received a formal complaint from the student; a later report said the university had bought Turnitin licences for lecturers to check AI use in essays.

1 Nov 2024 to 28 Jan 2026United StatesTurnitin AI-text detector
Orion Newby, an Adelphi University first-year student with language and auditory processing disabilities, received a zero in November 2024 on a World Civilizations paper after the professor suspected it was AI-generated and the university relied in part on AI-detection software; he was ordered to attend a plagiarism workshop and his appeal was denied, leaving him one finding from suspension or expulsion. Newby — who had written the paper with 15-20 hours of tutor support through the university's own disability program — said the detectors flagged his citations, and two other detectors scored the paper as human. After the family sued, New York State Supreme Court Judge Randy Sue Marber in Nassau County ruled on 28 January 2026 that Adelphi's finding and its denial of his appeal were 'without valid basis and devoid of reason' and ordered his record expunged. The family spent six figures on legal costs.
