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.

Teachers
Who teaches at Dun Laoghaire ETNS, 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
12.4teaching posts
Our estimate: about 12 teachers.
- Class teachersOne for each of the 8 mainstream classes 8
- PrincipalRuns the school and doesn't teach a class 1
- Special education teachers85 hours of support teaching a week 3.4
6 special needs assistants (SNAs) also work with pupils.
The NCSE has allocated 3.4 special education teachers and 6 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
