Inspection
Schools in Northern Ireland are inspected by the Education and Training Inspectorate. Since 2024 its reports end with a written summary and next steps instead of a grade, and there is no published list of outcomes.
Results
GCSE results, summer 2025
147 Year 12 pupils. We compare them with non-grammar post-primary schools across Northern Ireland, because grammar schools pick pupils by ability, so setting them against other schools wouldn't be fair.
A level results, summer 2025
86 pupils in the final year of A level or equivalent courses.

Getting a place
No entrance test. When more children apply than there are places, the school's own rules decide who gets in. Usually that means brothers and sisters of current pupils first, then children from its feeder primaries, then whoever lives closest.
As a Catholic school it may put baptised Catholic children first.
Apply through the Education Authority's online admissions system in January.
