Large Scale AI Grading of Handwritten Physics Assessments: Score Agreement and Olympiad Team Selection Outcomes

Read the original on arXiv AI →

The study evaluates GPT‑5.5’s ability to grade handwritten physics assessments, using 10,364 scanned pages from 520 submissions by 416 candidates across a national Olympiad theory exam, a final selection camp, and a university quantum‑mechanics exam. Each submission was graded twice, with the second round incorporating refined instructions after analyzing first‑round disagreements. The AI’s total‑score correlations with official marks ranged from 0.91 to 0.97, and it successfully identified the same five‑student team for the final Olympiad selection as human graders, though exact partial‑credit grading—especially in experimental work—remained challenging. "Reliable AI grading therefore depends on detailed rubrics and should be used as a second reader or audit tool under examiner control."

Grading Needs a Rubric, Not Intelligence

Small language models can grade open‑ended exam answers as reliably as much larger models when they use an explicit rubric. In experiments with six cost‑efficient model configurations, the rubric decouples grading from judge intelligence, with answer identity explaining 95.6% of score variance and judge identity only 0.2%. Removing rubric criteria or the official answer collapses reliability and inflates scores, showing the rubric’s essential role.
