arXiv:2606.24973v1 Announce Type: cross Abstract: We introduce a dataset of 32,534 double-marked real student responses to GCSE mock exams (GCSEs are the UK's national exams, taken at age ~16), spanning 328 questions across five subjects and including handwritten work. We test whether off-the-shelf large language models agree with examiners as closely as the two examiners agree with each other. We find that models overwhelmingly agree well with the examiner consensus across subjects, with the top performing models agreeing more closely with examiners than examiners agree with each other.

The proliferation of advanced LLMs and increasing research into their real-world applicability are driving a deeper understanding of their capabilities and limitations in specific, high-stakes domains.
This finding demonstrates LLMs' surprising accuracy in a complex, real-world assessment scenario, suggesting they could significantly impact education, professional certification, and other fields requiring human judgment.
The perceived gap between human and AI performance in subjective assessment tasks narrows considerably, potentially accelerating the adoption of AI-driven evaluation tools and reducing the need for extensive human intervention.

- · Traditional assessment methodologies
- · Labor-intensive grading industries
LLMs can reliably perform subjective assessments with high agreement rates comparable to, or exceeding, human inter-rater reliability.
This capability could lead to the widespread integration of AI into educational assessment, professional screening, and potentially legal or medical evaluations.
The development of 'AI-proof' or AI-resistant assessment strategies may become a critical area of focus, alongside a re-evaluation of the human role in high-stakes judgment.
