Same tier — for opposite reasons
On the dimensions where both rate the same, the table reads as "no difference." In reality they usually reach the same height for entirely different reasons. Here's what each says about itself.
employability — both S-tier
Engineering graduates enjoy direct corporate pipelines to Caterpillar, John Deere, Lockheed Martin, Rolls-Royce (North American HQ in Indianapolis), and Raytheon. Big Tech recruiting from Purdue CS has grown significantly with Amazon, Google, and Microsoft all maintaining active campus presence.
Dublin hosts European headquarters for Google, Microsoft, Meta, Stripe, Apple, and Salesforce, giving Trinity graduates unmatched proximity to tech employers. EU citizenship grants automatic mobility across 27 member states.
teaching quality — both A-tier
The 13:1 student-faculty ratio masks a split experience: introductory STEM lectures can exceed 300 students, while upper-division and graduate courses are small and research-intensive. Faculty are highly research-active with over USD 600M in annual research expenditures.
As a LERU member, Trinity prioritizes research-led teaching with a 12:1 student-to-faculty ratio. The Irish university system emphasizes small-group tutorials alongside lectures, particularly in arts and social sciences.
Where they genuinely diverge
