Investigation: California colleges and universities continue to renew Turnitin subscriptions despite the cost, faulty anti-plagiarism tech, and privacy issues

Colleges and universities renew Turnitin subscriptions year after year even though its flawed detectors are expensive …

The Markup Tara García Mathewson

Context & Ripple Effects

Turnitin’s AI-detection push followed its earlier launch of an AI-writing detector for a large academic customer base. This investigation shows that California institutions are continuing to buy the service even as questions about accuracy, cost, and data handling accumulate.

The story also fits a broader campus-monitoring environment: prior reporting documented data-collection and surveillance tools at a California college. The issue is therefore not only whether a detector works, but how much authority institutions give automated systems over students’ academic records.

First-order effects

  • Turnitin retains recurring business from California colleges and universities despite reported concerns about its anti-plagiarism technology, subscription costs, and privacy practices.
  • Students and instructors at renewing institutions remain subject to a tool whose reported faults can affect how academic work is assessed and questioned.

Second-order effects

  • Renewals can make it harder for institutions to move quickly to alternative academic-integrity processes, because existing workflows and staff practices remain centered on Turnitin.
  • Reports of false positives elsewhere, including students changing their writing to avoid AI-detector flags, raise the stakes for colleges that use detector outputs in academic-review processes.

Third-order effects

  • If institutions continue renewing disputed detection tools, academic-integrity technology may become embedded as core campus infrastructure before standards for accuracy, appeal, and data governance are settled.
  • The pattern points toward greater pressure for human review and clearer institutional rules around automated academic judgments, though the coverage does not establish what reforms California schools will adopt.

The trend: Higher education is normalizing AI-era academic surveillance tools while their reliability, privacy trade-offs, and role in disciplinary decisions remain contested.

    Every dime spent on Turnitin is a waste, and turns out it's a lot of dimes.  The AI “detection” is particularly wasteful. themarkup.org/artificial-i...

    And honest students are caught in the crossfire of an arms race between technology that mimics human speech and technology that claims to identify it. themarkup.org/artificial-i...

    “Turnitin monetizes student intellectual property and contributes to a culture of suspicion in education.”  —  I'm quoted in a recent article from @themarkup.org @calmatters.org and @chronicle.com  —  themarkup.org/artificial-i...

    Our investigation revealed institutions willing to renew Turnitin subscriptions year after year despite the cost, faulty technology and concerns about privacy and intellectual property raised by the company's ever-expanding paper database. calmatters.org/education/hi...  5/6

    I STRONGLY encourage all educators to read this amazingly well-researched article from @themarkup.org about the issues of AI-detection software and who really benefits from it (spoiler: it is not our students): themarkup.org/artificial-i...  #AI #GenAI #HigherEd  —  HT @jessifer.…

    Turnitin has been a staple purchase in #highered for decades, despite its rising cost, unsophisticated technology and highly problematic practice of demanding a perpetual license to any student writing its plagiarism and AI detector scans. https://calmatters.org/... @sundaylongre…
