I think it is frustrating too that when it is only such a small class, there should be absolutely no excuse for a child to fall through the cracks and teachers not realise that they aren't where they should be. My kids have constant assessment of their literacy skills and they are moved to different groups according to those results - and we're talking classes of 40+kids in Kindergarten and I think it's 65 for year 2. I do volunteer work in my DD2's kindergarten class for Literacy groups and what we have to do is take one of the groups, read their readers with them and do their sight words and then let the teachers know if any needed extra help etc. I did have a boy one day who really struggled with the book he had and when I told the teachers they said they would have to re-test him, so I just don't get why your school is so slack about it.
