"To be a top 10 MBA programme in three highly valued categories reflects extremely well the ethos and substance of the Trinity MBA," said programme director Karen Finigan.
"As we develop the Graduate School of Management and our partnership with the IMI, the prospects for building on our top 10 positions is unlimited," she said.

This year 64 per cent of students are non-Irish.
The UCD Smurfit School of Business, in a statement, said it had "once again maintained its presence in the top 100".
Prof Tom Begley, the new dean of UCD Business Schools, said that while, " we are pleased to be included in these rankings, the increased competitiveness among business schools across the globe highlights the need for ongoing investment in business education.
"We have always benchmarked ourselves against the best schools in the world and will continue to do so; in recognition of this we have recently made a number of senior international appointments at the school."
The vast bulk of the schools listed were in the US and Europe.
A joint eight-ranked school, Insead, is based in France and Singapore while the school ranked 21st, Ceibs, is based in China.
A second Chinese school, the Hong Kong UST Business School, was ranked 47th and a Canadian/Chinese school, University of Western Ontario/ Ivey, was ranked 31st.
