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.

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
30.2teaching posts
Our estimate: about 30 teachers.
- Class teachersOne for each of the 16 mainstream classes 16
- PrincipalRuns the school and doesn't teach a class 1
- Special education teachers180 hours of support teaching a week 7.2
- Special class teachersFor 3 autism classes 6
13.99 special needs assistants (SNAs) also work with pupils. 18 pupils are in special classes, which the class sizes leave out.
The NCSE has allocated 7.2 special education teachers, 4 special class teachers and 15.99 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. Known data issues
