Teachers in Ireland are paid better, better respected, given a lot more autonomy, are much less burdened by admin and planning than in the U.K.
That’s an enormous advantage right there. Ireland is able to attract better grads and retain them.
One of the reasons we moved back to Ireland was primary education, which is much more relaxed and engaging here. Irish students perform very well on international measures, so the approach clearly works. The very idea of SATS is seen as ridiculous here.
Secondary, I like the broad approach, the lack of pigeonholing, the focus on non academic matter (transition year, when done well, is awesome). On the other hand, if you’re really into your subject, A levels give you that depth and scope.
I went to Trinity and my year was a mix of Irish, NI and GB students. Their secondary background didn’t matter much in the end tbh.
