How would a 70 pupil infant school intake be organised?

[boddingtons]

Would it be two forms for each year plus one mixed class of all three years?

Oops not very clear! I meant 70 in each year not in whole school. Thanks.

We have:
2 x reception (30 each)
1 x Year 1 (20) reception (10)
1 x year 1 (30)
1 X year 1 (20) Year 2 (10)
2 X year 2 (30 each)

Clear as mud but it works!

This is how my DCs school does it.

70 is a horrible number for class organisation and the Infant class size regs keeping the classes to 30. There are two obvious options.
One is to have 7 classes of 30, which would be 2 reception classes, 1 class with 10 reception/ 20 year1, 1 class of year 1, 1 class of 20 year 1 and 10 year 2 and then 2 classes of year 2. This has the advantage of minimising teaching staff in 7 classes and that any appeals would be infant class size regs cases and therefore unlikely to lead to many successful appeals.
The other alternative is to have three classes of reception children with 24/23/ 23 in the class, then have 5 classes across the years 1 and 2. There would be 1mixed year class and then 2 year 1 classes and 2 year 2 classes, with 10 spare places across the 5 classes before the infant class size regs would come into force. This would mean 8 classes, therefore 8 teachers and therefore more expense. If the school was clever they would keep the two year 1 classes and the mixed year1/2 class at 30 and then have two small year 2 classes of 20 as this would mean that the school could argue infant class size regs when it comes to any appeal, based on future prejudice in year 1. The problem is that most schools are not as devious as me and would just split the 10 spare places up across the 5 classes and then be open to appeal that would not be an infant class size case.
The school would also need to look very carefully at the size of the junior classes because they could easily end up a 34 or 35 with a PAN of 70. Ultimately what will drive the classroom organisation would be the number of classrooms. A PAN of 75 would be far preferable from the point of classroom management as it would then be easy to split into classes that will all be infant class size regs cases.

I thought it must be more complicated than that . . . and it is! Thanks very much for the replies. I will ring the school on Monday to clarify exactly what the set up is but it will be a whole lot easier now I can ask "is it like this" rather than have the above explained to me over the phone!

one school round us had two classes per year but had an extra teacher for both classes in reception who would take small groups out of both classes for small group work.

Well I rang the school and it's 27 + 27 + 16 (in converted library) with 2.5 teachers and 2.5 TAs. For Year 1 and 2 there are 5 classes, one of which is mixed. The linked Junior is 75 PAN though currently only has 220 children so has two classes of less than 30 per year.

Would this mean any appeal would not be ICS? I'm appealing for the school where DD is at preschool (futile I know) and this is our allocated catchment school but some parents at DD's preschool didn't list this school and have been left with no place at all. Would they be better off appealing to get into this school rather than our current school, ie at least have a chance? Seems to me the school could potentially take another 5 children.
