The local newspaper has printed the photos of all the p1 classes of the schools in the area.
DS's current state primary class has 21 pupils in it. So that's my reference point, if you like.
What has surprised me is the sizes of the classes in the private schools. The big, well known hothouse one has 2 classes of 25 pupils (so bigger than most of the state schools). Then there is a girls school with 1 class of 17, which sounds fine. But there are 2 small private schools (one is a prep) where they have only 10/12 pupils (mostly boys).
Would other parents be concerned about sending their child, especially a girl, to a school where there are only 4/5 others of the same sex to make friends with?
