All Leaving Cert students studying languages will receive marks of 100% in lieu of oral assessments that were due to be held in Irish and modern European languages.
The measure has been announced by Minister for Education Joe McHugh.
Oral exams were due to begin on 23 March but have now been cancelled.
The oral assessment is worth 40% of overall marks in Irish, and 25% in modern European languages.
The deadline for submission of practical and coursework for the leaving cert has been extended to 15 May.
No decision has yet been made in relation to when schools might reopen, or on June’s leaving certificate exams.
