The Fianna Fáil leader has said the lack of clarity on the Leaving Cert is unacceptable.
The government has said the plan is for the exams to go ahead at the end of July.
However there's growing calls for the exams to be scrapped and replaced with predictive grading.
Fianna Fáil leader Micheál Martin says there needs to be clarity soon.
"The situation in relation to the Leaving Certificate is unacceptable.
"Every single government in Europe has been confronted about how to complete school leaving exams and prepare for a new higher eduction year.
"Never has there been such a lack of clarity and confusion.
"The fact that the reopening document published last week failed to publish it is remarkable."
