School principals are calling for detailed guidance on how the Leaving Certificate examinations are going to be managed.

Yesterday, Minister for Education Joe McHugh announced the delayed Leaving Cert exams will commence on 29 July.

Speaking on RTÉ's Today with Sean O’Rourke, the Principal St Patrick's Classical School in Navan, Colm O’Rourke, has said it is "unsatisfactory" that schools have received no information from the State Examinations Commission, or the Department of Education.

"We have not heard a word from the State Examinations Commission, or the Department of Education, all we have learned so far, has been learned from what we have heard in the media.  That is quite unsatisfactory," Mr O’Rourke said.

He said Minister McHugh has been too quick to make announcements in relation to the Leaving Cert.

"There has been no clarity on how this is going to work.  Making an announcement on Good Friday was silly. There has been too much attention paid to social media by ministers."

On the same programme the Principal of Fingal Community College, Sharon McGrath, called for guidance on how to manage the logistics of assessments.

She welcomed yesterday's clarification that the Leaving Cert was to go ahead on 29 July, but she said there are "significant difficulties in ensuring the safety of students".

"Not all schools are facing the same issues of trying to ensure that students can social distance.  Teachers are rolling up their sleeves and are extremely willing, but I am struggling to see the way.  We need guidance logistically on how we manage this."

The organising of written papers "are the least of our worries", as she said there are "significant concerns around the administration and assessment of practical exams and projects".

Mr O'Rourke agreed that the sitting of exams is "much easier" than the proposal by the Minister that students may be able to return to school for two weeks of classes before the exams commence, which Mr O'Rourke said would cause "massive problems".

He also called for clarity for teachers about "what work they will be expected to do, when the school year would reopen, if they're going have any holidays at all if they're expected to work online with Leaving students in June".

Earlier, also on the same programme, Aodhán O Ríordáin, Labour Party Spokesperson on Education, said the situation for disadvantaged students and those with additional needs still needed to be looked at.

He also said that he can't understand why Minister McHugh is refusing to cancel the exam fee of €160, describing it as "unreasonable".
