The three day conference has come to an end, with topics such as pay and conditions, health and safety and exam reform discussed by 500 delegates from all over the country.
It's understood the Department of Education plan to make the Leaving Cert less stressful for students by making the written exams worth 60 percent of their overall mark.
The remaining 40 per cent is to be made up of course work that it's expected will be graded by the student's own teacher.
However speaking to RedFM News, Ann Piggot from the ASTI says teachers are opposed to the proposal:
"We are the teachers, we are helping the students in the classroom. We don't want to be the final judge. We saw during calculated grades and accredited grades, the way the system went- we had great inflation as a result in the end. We like the external exams, we like the fairness of it; the fact that it's so impartial and we also like the way that every script is marked on the same marking scheme. If teachers are marking their own, everybody will be marking differently and that's not a good thing for a very important exam."
