The Minister for Education has been accused of ignoring advice on preparation for this year's Leaving Cert.
It comes after 500 student had their oral Irish exams postponed this weekend, due to Covid-19.
The State Examinations Commission is rescheduling the exams.
Labour Party education spokesperson, Aodhán O'Riordán, says the Minister needs to ensure the same situation is avoided in June:
"We now have been proven correct that Covid was going to have a negative impact on the Leaving Cert. We don't know what's going to happen when the exams themselves are taking place: between teachers being out, examiner's being out, students themselves being affected. This was always going to happen".
