The UK qualifications regulator, Ofqual, has fined Cambridge English £875,000 after automated marking errors led to incorrect IELTS results being issued to 62,794 candidates worldwide. The failures affected tests taken between August 2023 and September 2025, including examinations used for university admission, professional registration, and UK visa and immigration applications.
The errors occurred in the computer-marked Listening and Reading components of IELTS. According to Ofqual, a fault in the automated marking system caused 93,865 individual responses to be scored incorrectly across approximately 7.7 million tests taken during the two-year period. Around one third of those errors did not alter candidates’ component or overall scores, but the remaining cases required formal corrections.
Of the candidates whose results changed, 21,717 received a revised overall IELTS band score. Most saw their final score increase, while 1,115 candidates had previously received scores that were too high and later had them reduced. In almost every case, the adjustment amounted to 0.5 of an IELTS band, with only two candidates receiving a full one-band increase.
The regulator said Cambridge English did not identify the problem until September 2025, when updates to its monitoring systems uncovered weaknesses in the automated scoring process. Ofqual concluded that the organisation’s monitoring and error-detection procedures were inadequate, allowing the problem to continue undetected for more than two years.
Particular attention was given to candidates who had taken the Secure English Language Test (SELT) version of IELTS, which is used by UK Visas and Immigration (UKVI). Ofqual confirmed that 1,108 affected candidates had taken the SELT examination. According to the regulator, only four visa cases were directly affected by the incorrect results, and each candidate subsequently met the required standard after retaking the test.
In determining the financial penalty, Ofqual acknowledged Cambridge English’s cooperation during the investigation. The organisation accepted responsibility, entered into a voluntary settlement agreement and agreed not to challenge the regulator’s findings. It also committed to measures designed to prevent similar failures in future.
The regulator also took into account the scale of Cambridge English’s remedial response. According to Ofqual, the organisation has spent more than £6 million correcting results, compensating affected candidates, operating a dedicated 24-hour customer support service, and strengthening its quality assurance and monitoring systems. These actions contributed to a lower financial penalty than might otherwise have been imposed.
For the English language assessment sector, the case serves as a reminder that digital marking systems require the same level of scrutiny as traditional assessment processes. As awarding organisations continue to expand computer-delivered testing, regulators are placing increasing emphasis on system validation, continuous monitoring and the ability to detect errors before results are released. The incident is also likely to reinforce expectations around transparency and rapid corrective action when failures occur in high-stakes international examinations.
