Class sizes
Mainstream class groups, 2017/18 to 2025/26.
Why these won't match pupils by class
Mainstream class groups only. The source does not identify which standard/year group each class group belongs to. So these figures won't match the pupils-by-class figures exactly.
In 2025/26. Choose a figure to chart it.

Teachers
Who teaches at St Mary's National School, 2017/18 to 2025/26.
How we count teachers
Class teachers come from the Department of Education's class sizes: one for each mainstream class. Special education and special class teachers are the posts the National Council for Special Education (NCSE) allocates. We add a principal who doesn't teach a class where the Department's rules give the school one. These are posts, not people: part of a post can be a teacher shared with another school. Up to 2015/16 the Department counted every teacher itself. Known data issues
In 2025/26
3.8teaching posts
Our estimate: about 4 teachers.
- Class teachersOne for each of the 3 mainstream classes 3
- PrincipalAlso teaches one of the classes, so is counted with the class teachers in a class
- Special education teachers20 hours of support teaching a week 0.8
0.5 special needs assistants (SNAs) also work with pupils.
The NCSE has allocated 0.8 special education teachers and 0.5 SNAs for next year.
Teachers since 2017/18
Teachers each school year, by role
From 2019/20: our estimate, from class sizes and the NCSE's allocations. Dashed boxes: no special education figures were published for those years, so only class teachers and the principal are shown. Where there's no principal bar, the principal also taught a class. Known data issues
