It also becomes hard to start teams or activities when there are too few kids to pull from. And as PP said, so much depends on the teacher, the personality of the class, the style of the school, etc. I have seen good teachers more than effectively teach 30 kids while less-apt teachers can't manage 15. You won't know until you get there but luckily around here you can easily hear from others about a school's pros and cons. Pick what works for your family on all levels.
Agree on some of the social downsides. My DS was in a grade that was quite girl heavy. The pool of boys was just too small and each had their own set of quirks. He was much happier socially in a larger school and actually had far more boy academic peers as well.
I am also not sure that there are that many 15 student classes after K in private schools. Our private school class size was 22-24.
