Meanwhile the State Examinations Commission has said the 66 students from Libya due to sit the Leaving Cert in Tripoli can take the exam in Ireland or Malta because of the conflict in their homeland.
The Leaving Cert has been taken by students at the International School of the Martyrs in Tripoli each year since 1997.
The commission said it would not be possible to hold exams in Tripoli this year because of the highly unstable situation in Libya.
