The position of Trinity College Dublin in the latest international university rankings tables has slipped a small number of places, from 117th place to 120th.
Two Irish universities have seen their score in the Times Higher Education rankings rise; UCC moves from being categorised in the 350-400th place bracket, to between 301-350th.
Maynooth University has moved up into the top 400 this year.
NUI Galway has fallen from its place last year between 201st and 250th, to between 301-350th this year.

The Times Higher Education World University rankings are published annually.
They measure and compare the performance of institutions across the globe, taking into account teaching, research, international outlook, citations and industry income.
While university ranking tables have become hugely influential in driving policy at university and even at government level, critics say their methodologies are flawed, and that they fail to reflect the true value of many third level institutions or activities.
