St Louis Grammar

What St Louis Grammar does

St Louis Grammar School is a Catholic, state-funded grammar school located in Ballymena, County Antrim, Northern Ireland. Founded in 1924 and now in its centenary phase, it provides selective post-primary education to over 1,200 pupils aged 11–18 across Years 8–14, delivering GCSE and A-Level programmes within an explicitly Catholic ethos. Reported academic outcomes are strong, including 98.1% of A-Level entries graded A*–C and 98.8% of GCSE entries graded 7 or above at A*–C, and the school holds multiple sector accreditations (Autism NI, Eco-Schools Green Flag, Take 5, Gaelbhratach).

The school's core offering is classroom-based secondary education supported by a co-curricular programme that includes sport, music, and an alumni-led mentoring scheme launched in 2026. It has invested in STEM capacity through two new Science rooms opened in January 2026, partly financed by a £125,000 Wolfson Foundation grant awarded in February 2025. It is the first school in Northern Ireland to have all teaching staff TEEP-trained and the first to achieve SSAT "transforming" status across all 12 framework strands. Technology in use is standard for the sector (Google Education tools, Accelerated Reader literacy software) with no disclosed AI/ML components.

Revenue mechanics are dominated by Northern Ireland per-pupil government grant funding, supplemented by corporate sponsorship (Fibrus, JAQ Group, Macklin Group, and other regional firms), charitable grants, and community fundraising. The school employs approximately 59 staff (one source indicates 100+), with teaching and administrative functions delivered in-house. Operational expansion is expressed through facility upgrades and ecosystem partnerships rather than enrolment growth or new sites.
