yeah. but what about us kids? If the teacher have a tons in a class, they can't get to all and then their WASL or other test score would eventually drops.

I believe that the class size is not the issue here. My old school in asia had a total class size of between 55 to 61 and usually have 1-2 teacher in a class.

And the results show that asian kids have higher score in math than the U.S.
