The wording of the Infant class size compliance says
“no infant class ….shall contain more than 30 pupils while an ordinary teaching session is conducted by a single school teacher”. “

“Myth – If a class goes over 30, we can meet the class size duty by putting another adult in to support the teacher.
Not necessarily. They must be a ‘school teacher’ as set out in Annex A.
“School teachers’ do not include teaching assistants, higher level teaching assistants or other support staff. However, support staff may carry out ‘specified work’, such as delivering lessons to pupils, within infant classes in certain circumstances. In each case:
3.In practice this means that, although a school with infant classes must have sufficient school teachers to be able to teach its infants in groups of 30 or fewer per teacher, support staff, providing they meet the above criteria, may ‘teach’ infant groups when teachers are not available (e.g. when a teacher is away from their class on their Planning, Preparation and Assessment time).
4.Support staff must not be the main ‘teacher’ for an infant group and, where support staff are undertaking the more demanding aspects of “specified work” – particularly where they are working with whole classes – head teachers should have regard to the higher level teaching assistant (HLTA) standards in determining whether those staff have the necessary level of skills and expertise.
5.If a school were to use support staff instead of teachers to lead its infant groups, either as a permanent arrangement or for the majority of the school week on a regular basis, it would be in default of its class size duty.
Consequently, a school must employ sufficient teachers to enable it to teach its infant classes in groups of no more than 30 per school teacher.
