The ASTI has decided to re-enter talks with the Department of Education to discuss plans for this year's Leaving Cert assessments.
The union withdrew from talks with the Department earlier this week over proposals to prioritise a system of calculated grades.
It contended that the plans were "unacceptable", but yesterday said it had "constructive engagement" with the Education Minister.
The ASTI said today it has been told that oral and practical exams, as well as coursework, will go ahead this year.
The union also says it has been assured teachers will not have to rank their students like last year.
A spokesperson said the Minister was "unequivocal in her statement of commitment to holding the Leaving Certificate this year".
