In our local village school we only have 2 classrooms.
Class 1 is Rec, yr 1 and yr 2
Class 2 is year 3,4,5, and 6
There are about 52 children in the school
In class 1 there is 1 teacher, 1 classroom assistant and 1 eyfs trained ta.
In class 2 there are 2 teachers and 2 ta's who are split in the morning.
Ive had 2 children go through the school, and 2 going through now.
Its fine, I trust the school to seperate as they need to, years 3 and 4 have seperate english and maths every morning and then join with the others for geography, science etc.
Really has worked well for my children as the brighter one has pushed forward and been stretched and my son who has struggled has been helped being with the level he is comfortable.
In reception the children have their own eyfs trained teacher and she is lovely, the older children are usually on seperate tables in the same room.
I think it must be hard for the teacher to plan but our school has been doing it for 100 years so it must be working!!
