# AI Homework Tools Associated With 20% Exam Score Decline in Chinese Students
A study of 26,000 Chinese students has found that while artificial intelligence homework tools improve short-term homework performance, they are associated with a 20 percent decline in exam scores. The research indicates that this negative effect, described as a "brain drain," takes approximately two years to fully manifest.
The findings highlight a disconnect between homework performance and exam results among students using generative AI tools. While students using these tools initially show improved homework scores, their subsequent examination performance deteriorates significantly over time. The delayed emergence of this effect suggests that the impact on learning retention and understanding develops gradually rather than immediately.
The study comes as generative AI becomes increasingly prevalent in educational settings, with students worldwide adopting these tools for academic assistance. The research contributes to growing discussions about how AI integration in education affects genuine learning outcomes and student academic development.
