Same here! (about the people freaking out at around 26 kids)
When my daughter was in Kindergarten the class size's started out at around 28, but the school quickly added a third teacher and the class sizes settled out closer to 16. Well when that same group of kids moved to 1st grade they didn't add another teacher, so the two classes have around 28 kids. Parents freaked out! Thankfully most parents volunteered, so the teacher had a volunteer almost every day along with a college student who came three times a week.
Next year they are expecting more incoming students, but not adding another teacher. I know several parents who have organized meetings to discuss solutions. The big problem here is that up to 40% of the student body (at least according to the parent running the meeting) is coming from out of area. I guess the principle has tried to crack down on this, but parents go over her head to the school board and get permission for their kids to attend.
It's probably no coincidence that the same parents are usually also very active with the school and make large donations. I don't think it would upset me if they were bringing underprivileged kids here from other neighborhoods (they do that in another wealthy part of town), but that's not the case. These are for the most part wealthy families who just want their kids to go to a good school with out paying for expensive private schools.
I know some of the parents whose kids come from out of bounds, and they are wonderful families, but I also understand why people in this neighborhood are upset. They paid a lot to live here.
I know I was a little ticked when after searching for a house we could afford in this neighborhood we ended up with something much smaller than we would normally rent, and my old neighbor who was looking at the same time (we were both moving out of military housing) ended up on the other side of town in a house twice as big for around the same price, but their daughters still go to our neighborhood school.
