The Teachers' Union of Ireland is to recommend that members accept new Junior Cycle proposals in an upcoming ballot.
In a statement issued after a meeting of its executive committee, the union said it had comprehensively analysed the proposals and considered that they allayed the deep concerns expressed by teachers.
TUI President Gerry Quinn said that a whole range of concerns have been addressed in a satisfactory way.
Speaking on RTÉ's Drivetime Mr Quinn said that previous proposals were ambiguous and ambivalent.
He said that there is now a situation where there is "deep blue water" between external and school based assessments.
Mr Quinn said that all subjects will have practical and project work, taking the pressure off students in their final exam.
He said the TUI will not be participating in training until members lift the directive.
Mr Quinn said it is hoped that there will be a ballot result by the end of September.
Responsibility for the administration and assessment of the Junior Certificate will remain with the State Examinations Commission and will not be foisted on schools."
The move comes after intense negotiations, and Mr Quinn said he believes the latest proposals "will enhance second level education while protecting the working conditions of teachers."
The ASTI executive meets tomorrow to consider its attitude to the deal. Earlier this week, two members of their executive called on teachers to reject the deal.
