- Igor Chirikov (UC Berkeley professor) reports that “excellent” grades rose by 30% in AI‑useful classes after ChatGPT’s 2022 release, based on data from a Texas research university.
- Texas research university (a selective school with over 50,000 students) showed flat grade trends in courses where AI is not useful, such as sculpture and lab‑based classes.
- Homework‑heavy courses (e.g., English composition and coding) experienced higher rates of grade inflation, indicating AI‑assisted boosts for unsupervised assignments.
- Faculty are sometimes incentivized to grade leniently because student evaluations affect promotion, which may amplify AI‑driven grade inflation.
- Universities are adopting handwritten or oral exams and AI‑integrated assignments that require proper documentation of LLM use to curb cheating.
- The broader trend shows that grade inflation has been rising since the early 2000s, and AI appears to amplify existing patterns rather than create a wholly new phenomenon.
Why it matters: Students who use AI tools gain higher GPAs, while colleges risk devaluing their credentials as inflated grades obscure true mastery; faculty must redesign assessments, increasing workload and prompting policy shifts to preserve academic standards. The trend also pressures accreditation bodies to reassess grading metrics, and employers may question the reliability of GPA as a hiring signal.
