Secondary school teachers have decided to hold a series of strikes from September in support of their ongoing opposition to new Junior Cycle proposals.
The decision was taken at a meeting of the leadership of the Association of Secondary Teachers Ireland yesterday.
ASTI members gave a mandate for industrial action when they voted on the issue last September.
The union's 25-member Standing Committee plans a series of one-day strikes to take place between September and December.
The ASTI continues to oppose the Junior Cycle proposals.
However the Teachers' Union of Ireland has accepted them.
The ASTI has said there is now a window of opportunity for the next minister for education to resolve members' outstanding concerns.
In a statement issued this evening the union said those concerns included concern at an increased workload and bureaucracy for teachers.
They are also concerned that there is no external assessment for oral exams in Irish and modern languages.
The issue of Junior Cycle reform is expected to be a big debating point when the union meets after Easter for its annual convention.
