UK A-level grading algorithm (August 2020)
When the pandemic cancelled exams, the U.K.'s exams regulator Ofqual used an algorithm to standardize teacher-assessed grades. It downgraded roughly 40% of students' predictions, with the steepest cuts falling on students from disadvantaged areas and smaller schools.
Within days, after street protests and a government U-turn, the algorithm was scrapped and students received their teachers' grades.
The collapse damaged public trust in algorithmic decision-making in high-stakes settings and showed that opaque scoring systems can be reversed under pressure.
Like CRANE's AI triage, the A-level algorithm replaced human judgment with an opaque system that could not explain its decisions, and it was abandoned when the public saw the results.
