Class sizes

Mainstream class groups, 2006/07 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.

Teachers

Who teaches at St Marys National School, 2006/07 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

5.3teaching posts

Our estimate: about 5 teachers.

  • Class teachersOne for each of the 4 mainstream classes 4
  • PrincipalAlso teaches one of the classes, so is counted with the class teachers in a class
  • Special education teachers32.5 hours of support teaching a week 1.3

0.5 special needs assistants (SNAs) also work with pupils.

2026/27 allocations

The NCSE has allocated 1.2 special education teachers and 0.5 SNAs for next year.

Teachers since 2006/07

Teachers each school year, by role

To 2015/16: the Department of Education's count of every teacher. 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.
