The Education Minister Jan O'Sullivan has urged teachers' unions to reconsider a strike planned for next week.
Secondary teachers represented by the ASTI and TUI unions are due to begin industrial action next Tuesday after they were asked to grade their own students for Junior Cert exams.
The Department of Education said it was willing to compromise, with teachers only marking 40% of the exam.
Speaking in the Dáil this morning, Education Minister Jan O'Sullivan said nobody would gain anything from a strike.
"I've said publicly that I think this is disappointing and I believe it is a disproportionate response to the compromise proposals which remain on the table," she said.
"I would urge both unions to reconsider their position and reengage in talks rather than proceeding with a strike that serves no one's interests."
