The UK Department for Education (DfE) is testing the use of AI to produce writing samples used in the assessment of pupilsâ literacy standards as they move between primary and secondary school, claiming it cuts annual costs by 95 per cent.
Around 2000 moderators are asked to check the standard of pupilsâ writing at the end of key stage 2 (KS2), a critical moment in a childâs educational pathway in England and Wales. To ensure that grades given by teachers are standardised, the moderators cross-check pupilsâ work against samples of writing usually drawn from actual work produced by schoolchildren. That process costs around ÂŁ100,000 a year.
Starting this year and next year, some moderators will AI-generated output created by ChatGPTâs GPT-5 model.

The experiment is limited for now. DfE says GPT-5 is currently being used to create three collections of writing for one standardisation exercise, while one full exercise in 2026-27 and 2027-28 will continue to contain scripts written by children and obtained under the previous contract.
Around 20 experienced local authority moderation managers will review the AI-derived material for authenticity before it is used. The department plans to decide in spring 2027 whether to continue producing samples this way or return to procuring them from an external supplier. Its transparency record lists no formal impact assessment for the system.
However, the use of AI in a key part of educational assessment has raised questions.
âHaving an exemplification of writing that is not a real childâs writing for me creates a philosophical and ethical issue,â says at Anglia Ruskin University, UK. âThe worry is that AI shifts our perspective of whatâs acceptable in writing, or what is a good standard, or something like that.â
Clarkson, who studies KS2 writing assessment and moderation, has heard from a number of moderators who have raised concerns about the potential use of AI-generated samples. âEssentially [their criticism] just centres around the fact that itâs not real children,â she says.
The consequences of this are impossible to predict, she says. âIs it a concern if we donât use real childrenâs writing? Who knows? I guess we donât know what the impact is until we can measure the impact.â
The DfE didnât respond to 51¶ŻÂțâs request for comment.
The use of AI in this way shouldnât affect which secondary schools pupils end up at, since the KS2 writing assessments take place after pupils have been assigned to their new schools. But how well children match up to the synthetic samples could dictate the level of support they receive when they enter their next school.
Because AI can tend to produce flat or bland writing, there are worries that children who speak English as a second language or who are neurodivergent and so may not use the same language as the majority may be discounted. DfEâs notes that âLLMs produce texts that often [exclude] atypical vocabulary and sentence structures that might be used by neurodivergent or non-native [English-speaking] studentsâ â something it plans to mitigate by âthorough reviewâ.
The assessment also points out that the AI-generated outputs will be âheavily reviewed and editedâ and subject to review before being used in standardisation processes.
âUse of AI is seeping into all aspects of our lives and without proper governance, we do not know what the implications will be,â says at the University of Oxford. âIn assessment, there is a concern that there will be a backwash, with the AI-generated materials becoming the standards that teachers try to get pupils to emulate. This could lead us into some strange places.â
