AI vs professors: who grades better in physiotherapy?
NCT ID NCT07677202
First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time
Summary
This study compares how well large language models (AI like ChatGPT, Claude, and Gemini) can grade written clinical-reasoning exams from third-year physiotherapy students, compared to faculty assessments. Researchers will have AI and human teachers score the same anonymized exams using a standard rubric, then measure how much their scores agree. The goal is to see if AI can reliably support grading in health education, potentially saving time and reducing variability between human graders.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Large language models (AI like ChatGPT, Claude, Gemini)
- What this could lead to
- If successful, AI could help grade exams in health education, freeing up faculty time and providing consistent feedback.
- What could go wrong
- This is a small, early-stage study with 65 exams. AI may not match human judgment on complex reasoning, and results may not apply to other subjects or schools.

Who is studied
The study population comprises undergraduate students enrolled in the course "Specific Methods in Physiotherapy" (third year of the Physiotherapy Degree) during the study period, approximately 60 to 80 students. As part of the course, each student produces a written clinical-reasoning case examination. The de-identified examinations from consenting students constitute the units of analysis and are assessed independently, using the same predefined rubric, by faculty (reference standard) and by three large language models. No clinical intervention is applied and participation does not affect students' official grades, which are determined exclusively by faculty.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Students officially enrolled in the course "Specific Methods in Physiotherapy" (third year of the Physiotherapy Degree) during the study period. * Submission of a completed written clinical-reasoning case examination as part of the course. * Provision of informed consent for the anonymized examination to be used for educational-research purposes. Exclusion Criteria: * Refusal to provide, or withdrawal of, informed consent. * Blank, incomplete, or non-evaluable examinations (e.g., no developed written response). * Examinations that cannot be reliably de-identified prior to assessment.
