In my stepson's school district in Oregon, kindergarten class sizes will increase next year from 21 to 34 students, grades 1-5 from 25 to 35 students, middle schools from 30 to 38 students, and high schools estimate class sizes will average 44 students.

We live in Washington. Here, class sizes have been around 20-25 students. DD will be in an accelerated program for gifted students next year and class size is capped. (The class is filled based on test scores and there is a waiting list.)
