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
32.1teaching posts
Our estimate: about 32 teachers.
- Class teachersOne for each of the 25 mainstream classes 25
- 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 teachers102.5 hours of support teaching a week 4.1
- Special class teachersFor an autism class 1
4.83 special needs assistants (SNAs) also work with pupils. 3 pupils are in special classes, which the class sizes leave out.
The NCSE has allocated 4 special education teachers, 2 special class teachers and 6.83 SNAs for next year.

Teachers each school year, by role
