When I worked in a relatively well to do suburban district I had class sizes up to 35 students. Because I was a math teacher, administration did their best to keep our class sizes under 30, teachers of other core classes were more likely to have 30+ students, and classes that didn't have standardized tests might have more than 35. If I recall correctly, every year I taught 9th graders, who are often hyper nutjobs.
