Summary
After Covid-19 disrupted the 2020 Leaving Certificate exams, Ireland's Department of Education and Skills used a calculated-grades model to issue student results on September 7. The Department later confirmed coding errors in how the model handled Junior Cycle data, resulting in incorrect grades. About 6,100 students received upgraded results, and college-offer eligibility had to be reassessed.
