AI is inflating student grades, and the effect points to outsourced work, not better learning

A UC Berkeley study of over 500,000 grades found that student marks in writing and coding courses increased significantly following the release of ChatGPT. This grade inflation is primarily isolated to homework assignments rather than in-class testing, suggesting that students are increasingly using artificial intelligence to complete tasks instead of developing subject mastery. These findings indicate that current assessment methods may no longer accurately measure student learning or reflect individual academic performance in a landscape where generative tools are widely accessible.
