Can AI write national exams?

Artificial intelligence can draft exam questions in seconds. But speed is not the only consideration. For national, high-stakes exams, we need confidence that assessments are fair, reliable, and aligned to curriculum standards.

Our latest empirical study explores a critical question: How well do AI-authored exam questions perform compared to those written by experienced human assessors?

What the study examined

203 students sat a GCSE-level Biology practice question paper with both AI-authored and human-authored questions.

The study compared the questions across three areas:

• statistical performance based on student responses
• professional judgement by teachers
• quality review by senior assessment experts.
