AI Use Sparks Grading Surge and Policy Scrutiny in Universities

German higher‑education institutions have no nationwide rules on generative‑AI tools such as ChatGPT. Individual universities, faculties, and exam boards decide whether AI assistance is permitted, require prior written approval for theses, and often demand specific disclosure of the tool, purpose, and extent of use. Violations can lead to failing grades, loss of exam attempts, or other academic sanctions. A recent CHE survey found 65 % of students across selected fields already use AI weekly.

A separate analysis by the University of California, Berkeley examined more than 500,000 grades from a large Texas research university spanning 2018‑2025. Using the launch of ChatGPT in November 2022 as a breakpoint, the study identified a 13‑percentage‑point increase in top grades in courses where assignments are easily automated by AI, while courses emphasizing oral presentations saw no change. Overall grade averages rose modestly by 0.12 points. The authors argue the rise reflects AI completing assignments rather than enhancing learning and recommend redesigning assessments to limit AI assistance or require transparent documentation of its use.
