Increasing class sizes in independent schools - does it matter?

[gobbledy]

My ds is currently in reception at a smallish independent school. His class size is 20 boys. We've heard through the grapevine that this is going to increase next year ie some new boys are joining and afaik no-one is leaving.

They currently have one teacher and one assistant. Children with sn tend to have their own helper who is not involved with the rest of the class.

I'd like your honest views - does this matter? My first view is that it does, at least to ds - he is bright but will tend to sit back and do nothing if left to his own devices, and we thought he would basically just be ignored in a state primary class of 30. Really not sure the teachers will be able to cope with more than 20 fairly physical boys! We are not super-rich and private school means sacrifices for us as parents.

Honestly - any views?

I can't see the point of paying for an education if you're not going to get small class sizes!

My ds is in a state primary school. There are 29 in his class - but they have a teacher, a TA and at least 2 parent helpers every day. Just becasue it's a big class doesn't mean that children get ignored.
