American students are relying on AI to support their writing assignments far more than their Australian or British peers, according to data collected by Turnitin.

The company, used by universities worldwide to check text for evidence of cheating, found that US-based higher education students are “offloading” their writing to AI at double the rate of their overseas counterparts.

Analysis comparing student output assessed by the company’s detection tools found 19.4 per cent of those at US institutions hit the more than 80 per cent threshold for AI usage, versus 10.2 per cent in Australia and 9.8 per cent in the UK.

The Turnitin Learning Integrity Insights report also looked at dependence on the burgeoning technology across age groups, finding that American university students are using AI more than those at school.

About half of the assessed work in the US higher education system features “at least some” AI writing, according to Turnitin’s detection software – but less than a third of work submitted by school pupils (29.8 per cent) does.
