The ASTI has said that representatives had “constructive engagement” with the Minister for Education and her officials on the Leaving Certificate today. The Association of Secondary School Teachers in Ireland (ASTI) has said that work is being done with a view to finding a resolution to the current impasse. Last night, the ASTI announced that it was withdrawing from discussions on the Leaving Cert 2021 pending a guarantee that the talks will focus on the Minister’s stated objectives of planning for examinations and scoping out a corresponding measure.
