Wensleydale School, situated in the heart of the Yorkshire Dales, has embarked on a groundbreaking trial that places artificial intelligence (AI) at the centre of the marking process for students’ mock examinations. The initiative positions Wensleydale School as one of the few institutions in the north of England to integrate AI technology directly into the assessment workflow.

Headteacher Julia Polley remarks that the principal motivation behind the trial is to deliver feedback that is both rapid and richly detailed, while also removing any unconscious bias that may arise when a teacher knows a pupil personally.

In the early phase of the trial, however, the introduction of AI has not reduced staff workload. Instead, teachers at Wensleydale School have found themselves double‑marking papers—first using the AI system and then reviewing the results manually—to ensure accuracy and to gauge the technology’s effectiveness.

Selection of Subjects and Rationale for the Trial

The trial focuses on subjects that traditionally require longer, discursive answers—namely English, history, geography and business studies. These subjects generate responses that are “quite wordy,” a characteristic that, according to Headteacher Julia Polley, makes them ideal candidates for testing AI’s capacity to handle subjective marking criteria.

"Our staff marked the papers as well so it wasn't like they were just using it as a 'we don't have to do any marking'," Headteacher Julia Polley explained. "We just wanted to see whether AI would be accurate, whether it would misinterpret anything and what sort of feedback it would give us."

After an initial period of observation, Headteacher Julia Polley reported that the school was "really impressed" because the AI system supplied feedback that, while achievable by human teachers, would normally require a substantial amount of time.

Financial Implications and Practical Logistics

The cost structure attached to the AI marking service is calculated per extended answer, with a charge of 45 pence for each question that receives a detailed evaluation. Headteacher Julia Polley acknowledged that such pricing could become a limiting factor for larger institutions that process a high volume of examinations.

Wensleydale School therefore allocated an initial budget of £600, purchasing a total of 1,250 credits to be used specifically on English and history mock exam papers. The technology demands that each exam question be barcoded and uploaded individually, a requirement that presented a logistical challenge during the early stages of the trial.

"The only thing I was worried about is some misconceptions that teachers were trying to shirk their duty of marking and that's not the case at all," Headteacher Julia Polley said.

Initially, the teaching staff at Wensleydale School were "absolutely aghast," reacting with a strong desire to retain direct involvement in the marking process. According to Headteacher Julia Polley, the reaction was rooted in a professional need to understand precisely where pupils stood in their learning journeys.

"So I think it will always be used as a tool just to reassure and it's like a sense check to make sure what we are saying is right with what exam boards will say," Headteacher Julia Polley added.

Bias Mitigation and the Promise of Depersonalised Scoring

One of the central arguments advanced by Headteacher Julia Polley is that AI could help keep marks as depersonalised as possible. The concern is that teachers, familiar with individual pupils, might unintentionally grant a "benefit of the doubt" to students they know are striving hard.

"We don't want our teachers to interpret what the kids have written and give them the benefit of the doubt because they know them and they know they're trying hard," Headteacher Julia Polley asserted. "That was the bit that we were trying to unpick, AI won't see it that way."

By removing the personal relationship from the marking equation, the AI system aims to produce a purely criteria‑based assessment, thereby reducing the risk of unconscious favoritism.

Future Applications Within Wensleydale School

Looking ahead, Wensleydale School intends to broaden the use of AI beyond mock examinations. Potential future applications include using the technology for end‑of‑topic tests and for generating practice exam questions that can be automatically graded.

Expert Perspective on AI Adoption in Education

Dr Theocharis Kyriacou, associate professor of artificial intelligence at York St John University, contextualised the trial within the wider national framework. Dr Theocharis Kyriacou noted that government guidance on the use of AI in schools was only issued a year ago.

The Department for Education clarified that educators may employ AI tools, provided they exercise professional judgement to verify the accuracy and suitability of any output generated by the technology. A spokesperson for the Department for Education emphasized that "the final responsibility always rests with them and their school or college."

According to Dr Theocharis Kyriacou, AI adoption remains in its infancy, with schools experimenting on a limited scale. "It's still in its very early adoption phase, so there is interest and experimentation from schools, and that's rising rapidly," Dr Theocharis Kyriacou observed. "But deployment and use is patchy and uneven at the moment; it's still only used for low stakes tasks, such as drafting feedback, quizzes or resource creation."

Dr Theocharis Kyriacou highlighted two major benefits that AI could bring to pupils and teachers alike. For pupils, consistent marking and faster feedback could improve learning outcomes. For teachers, AI could alleviate the notorious workload pressures that see many educators putting in more than 50 hours a week—a situation Dr Theocharis Kyriacou described as "unsustainable."

"It's time at the end of the day, it saves them time producing extensive and detailed feedback and personalised feedback for their students," Dr Theocharis Kyriacou said.

However, Dr Theocharis Kyriacou warned against a wholesale replacement of human marking. The professor argued that completely outsourcing marking to AI would strip teachers of a core professional skill.

"On the other side of how the student perceives being marked by AI, I've looked at some conversations on different forums and I can see that there's this distrust and dislike about being marked by AI," Dr Theocharis Kyriacou added. "There can be distrust from parents if they don't understand how these things are used."

National Association of Head Teachers Stance on AI Marking Trials

The National Association of Head Teachers (NAHT) has voiced its support for AI marking trials such as the one underway at Wensleydale School. Sarah Hannafin, head of policy at NAHT, explained that AI tools hold the potential to free up teachers and school leaders from routine administrative duties, allowing them to focus on tasks where their expertise has the greatest impact.

Sarah Hannafin stated, "AI tools have the potential to deliver opportunities for the education system and reduce administrative burdens on teachers and school leaders – allowing them to focus on areas where their expertise can have the greatest impact."

She continued, "The potential for teachers to be supported by AI tools in the marking of mock exams should be explored and trials enable schools to evaluate the benefits and challenges for both staff and students."

Crucially, Sarah Hannafin stressed that transparency must be maintained throughout any AI deployment. "Importantly, there must be transparency for everyone about when and how AI tools are used and they must remain open to challenge," she affirmed.

Community Reaction and Media Coverage

Local radio outlet GREE Sounds featured a segment titled "Listen to highlights from North Yorkshire," which included commentary on the AI marking trial at Wensleydale School. The broadcast invited listeners to catch up with the latest episode of Look North, where the story was discussed in further detail.
