GPT-4 shows comparable performance to human examiners in ranking open-text answers
GPT-4 presents significant opportunities for education by potentially reducing teacher workload through automated grading. This study examines GPT-4's capacity to replace human examiners in ranking and point-assessing open-text answers. Key findings indicate that GPT-4 performs comparably to human examiners in ranking tasks without significant bias, but exhibits a length bias in point assessment, particularly in batch grading. This suggests a nuanced role for AI in educational assessment, advocating for its use as an assistant in quality-based ranking and in single-answer point assignment tasks.

Ethical Considerations & Future Outlook
While GPT-4 shows promise, teachers should not fully delegate grading without oversight. AI cannot be held responsible for misgrading. Its role is best suited as an assistant, particularly for ranking tasks or offering an additional layer of oversight. Future research is needed for different disciplines, languages, and more complex question types to validate broader applicability.
Summary: GPT-4 serves as a powerful assistant in educational assessment, but human oversight and ethical considerations remain paramount for responsible implementation.
