I have been studying Italian in Dublin for a few years. The Italian Cultural Institute in Fitzwilliam Square is good, but a lot depends on the teacher. I experienced a few years of good teachers there but dropped out when two classes were amalgamated and the teacher was unable to cope. You can study Italian at a beginners level in UCD as either an add-on to a B.A degree or as part of a Modular B.A. (night-time classes, twice weekly, 6.30 - 9.30). I tried this for a year and managed to pass the exam but, be advised, it is very biased towards Italian culture and literature and not great on basic day-to-day Italian. I dropped out at the end of first year and decided to try get my language skills up before resuming. Unfortunately, studying Italian in Ireland is a lot harder than either French, Spanish or German, where the various Institutes have a far greater range of classes geared to all levels.
