Class sizes
Mainstream class groups, 2023/24 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

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
40.4teaching posts
Our estimate: about 40 teachers.
- Class teachersOne for each of the 26 mainstream classes 26
- PrincipalRuns the school and doesn't teach a class 1
- Deputy principalDoesn't teach a class either, as larger schools and those with five or more special classes have one 1
- Special education teachers285 hours of support teaching a week 11.4
- Special class teachersFor an autism class 1
9.99 special needs assistants (SNAs) also work with pupils. 6 pupils are in special classes, which the class sizes leave out.
The NCSE has allocated 11.2 special education teachers, 1 special class teacher and 9.99 SNAs for next year.
