Irish students who want to study in the UK after Brexit, or UK students who want to attend third-level here, have certainty about continuation of the current fees regime for the duration of their studies if they start this September.
Nor will there be any change to student grants, and Irish students in the UK will also be able to access student loans there. In essence, everything will continue as if the UK was still in the EU.
For now, there are no guarantees beyond the academic year starting this September, and longer-term arrangements await a wider settlement around Brexit.
In the worst-case scenario, the alternative is students being treated as "international" students in each other's countries and paying higher fees.
Both governments have committed to maintaining the common travel area, which gives reciprocal rights to education and other services for Irish and British citizens in each other's countries.
Higher Education Minister Mary Mitchell O'Connor recently told the Oireachtas Education Committee that maintenance of the common travel area was a priority.
