US College Students Lead AI Writing Use, Turnitin Report Finds

Nearly one in five submissions from U.S. higher education students show high levels of AI-assisted writing, according to a Turnitin report released Tuesday, highlighting growing use of generative AI and increasing institutional oversight of academic integrity.

The Turnitin AI report found that 19.4% of written submissions from U.S. higher education students received an AI writing score above 80%, nearly double the rates recorded in the United Kingdom and Australia. The report analyzed submissions processed through Turnitin’s AI writing detection tools between October 2025 and April 2026.

The study examined 33 million submissions from U.S. institutions, 2.1 million from the United Kingdom, and 3.1 million from Australia. In comparison, 9.8% of higher education submissions in the United Kingdom and 10.2% in Australia scored above the 80% AI writing threshold.

AI-assisted writing appeared less common among secondary school students. Across all three countries, only 5% to 6% of submissions recorded AI writing scores above 80%.

Educators Take Larger Role in AI Policy

The Turnitin AI report also found that educators are increasingly making decisions about how artificial intelligence is used in classrooms.

In a poll of 160 webinar participants, 48% said teaching and learning leaders were primarily responsible for implementing AI-related tools and policies at their institutions. That exceeded responses for IT and technology leaders, cited by 17%, and cross-functional committees, cited by 16%.

Turnitin based its broader findings on qualitative and quantitative research collected during more than 60 education events held in the first half of 2026. The company also analyzed student interactions with Turnitin Clarity, its AI writing transparency platform.

The report said educators increasingly want insight into how students use AI throughout the writing process instead of relying only on detection after assignments are submitted. Respondents identified transparency, customizable assignment settings, and support for different assignment formats as their top priorities.

The findings reflect a broader shift as schools and universities establish policies defining when AI tools are permitted, how students should disclose their use, and how artificial intelligence fits into teaching and assessment.

Institutions Seek Greater Flexibility and Transparency

The Turnitin AI report said many educators want assignment-specific controls that allow instructors to distinguish acceptable AI assistance from excessive reliance on generative tools.

For colleges and universities, the focus extends beyond identifying AI-generated content to determining whether students are using the technology in ways that support learning objectives. According to the report, concerns are greater in higher education, where heavy AI use appears significantly higher than in secondary schools.

“Every educator I talk to wants the same two things: they want to see how their students are actually using AI, and they want to decide for themselves when it belongs in an assignment and when it doesn’t,” said Annie Chechitelli, chief product officer at Turnitin.

“Our job is to give educators the visibility and the flexibility to make that call in their own classroom,” Chechitelli said.

The Turnitin AI report also noted growing policy activity in the United States, where some states have introduced requirements for school districts to adopt formal AI policies or follow centralized frameworks. Those efforts come as institutions continue to debate accountability, consistency, and responsible use of artificial intelligence in education.

Turnitin said it serves more than 16,000 customers across 185 countries and territories as schools, colleges, and universities continue adapting assessment practices in response to the rapid growth of AI tools.
