No letter
No letter for Holy Trinity Sen N.S.
Ireland publishes no exam results school by school, and section 53 of the Education Act 1998 restricts comparing schools by them, so this school has no letter and nothing here ranks it. Its facts are the Department of Education’s; its inspection reports are linked below.
What the Department of Education does publish for Holy Trinity Sen N.S. is on this page: its pupils each September since 2015/16, girls and boys, its patron and ethos, whether it teaches through Irish, whether it is in DEIS, and its inspection reports.
Newspapers print lists of how many of a school’s leavers go on to college. Those count destinations, not exam results, and depend on who a school takes in; we don’t use them.
