Admissions information
The St Louis Grammar School Ballymena entrance test is the SEAG transfer test, used by grammar schools across Northern Ireland. Here is everything you need to know about the St Louis Grammar School, Ballymena, admissions criteria and exam structure.
St Louis Grammar School, Ballymena selects pupils on academic ability through the SEAG Entrance Assessment, the single transfer test used by the great majority of grammar schools in Northern Ireland. The assessment is provided by GL Assessment on behalf of the Schools’ Entrance Assessment Group and consists of two papers, each assessing English (or Gaeilge) and Mathematics.
Each of the two papers lasts 60 minutes and contains a mix of multiple-choice and free-response questions, with answers recorded on a separate answer sheet. The papers are taken on two Saturdays a week apart, and a pupil’s marks across both papers are combined into a Total Standardised Age Score (TSAS), which is age-standardised so that younger children are not disadvantaged.
Parents register their child to sit the SEAG Entrance Assessment online through the SEAG website. For September 2027 entry, registration opens on Monday 18th May 2026 and closes on Friday 18th September 2026. Parents must then name St Louis Grammar School, Ballymena on their Education Authority Post-Primary Transfer Form during the open application period.
SEAG Statements of Outcomes are released to parents on Saturday 23rd January 2027, after which families list their preferred schools through the Education Authority. The Education Authority informs parents of their child’s allocated school in May 2027. A high TSAS does not guarantee a place, as places are allocated in strict rank order when a school is oversubscribed.
