AI use in schools linked to declining exam performance
A 30-month study of more than 25,000 secondary school students in China has revealed a correlation between the use of generative artificial intelligence and a decline in exam performance.
Researchers from the University of Stockholm and the University of Hong Kong found that while AI tools help students complete assignments more efficiently—increasing homework grades by roughly 18% and reducing task time from 64 to 45 minutes—the benefits do not translate to unassisted testing. In closed-book monthly exams conducted without digital tools, student results dropped by approximately 20% after six months of AI usage. The study also noted a gradual negative impact on entrance exams for high school and university, with the most significant effects appearing after approximately two years of use.
