No letter

No letter for Mercy College Coolock

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 Mercy College Coolock 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.

Getting in

Getting a place at Mercy College Coolock

Every school admits under its own published admission policy; no admissions numbers are published.

Families apply to Mercy College Coolock directly, usually in the year before their child finishes sixth class; the school’s yearly admission notice gives the dates for applying and for its decisions.

A school with more applicants than places admits on the criteria in its admission policy, often brothers and sisters, the area it serves and, for post-primary schools, its feeder primaries. A family refused a place can appeal.

It takes girls only. It is in DEIS, so it has extra support for pupils from disadvantaged areas.
