Trinity College has been ranked within the world's top 100 universities in the latest international third level League tables due to be published tomorrow.
For the first time in five years, the college is within the top 100 Quacquarelli Symonds (QS) World University Rankings, in 98th place.
The fact that Ireland has had no university in the top 100 over the past number of years has been interpreted by some as a symptom of recent underinvestment in the sector.
UCD is the country’s second highest ranked university and the only other institution to make the top 200.
However, its placing has fallen slightly in these latest tables from 173rd to 181st place.
QS uses six indicators to rank institutions.
They include a college's reputation among other academic and employers, as well as employment outcomes; the number of citations in academic journals, and involvement in international research collaboration.
The ratio of students to faculty staff, as well as ratios of international students and faculty members, are also used in calculating scores.
