There are hopes that new proposals could bring about a breakthrough in the secondary school teachers dispute.
A campaign of industrial action that closed hundreds of schools was suspended earlier this month to facilitate new talks, which ended in the early hours of this morning.
A document focusing on pay levels and working hours flexibility has now been hammered out.
The ASTI will now put the deal to its 23-member standing committee, and then to its 180-member central executive committee.
Past proposals have previously fallen at one or other committee stage.
One of the main sticking points for the ASTI has been the restoration of pay for new teachers, which is due to be done under the Lansdowne Road Agreement; teachers want it to happen now.
Minister for Education Richard Bruton would not say what kind of deal is on the table.
"These talks are continuing, and the best way to hopefully ensure a good outcome is to respect the privacy of that process," he said.
