Does anyone know the official CPS policy regarding class size? How many children do you have to have before they are required to provide another teacher and split the class?

In my school (I am a teacher in a SEES) we have a few classrooms in the mid to high 30's. Two years ago we had 40 in kindergarten with no assistant in the room. I met many teachers at the recent strike rallies with similar class sizes at schools across the city.

I remember a few years ago there was an uproar against Mr. Huberman's threat to raise class sizes to 37. But 37 seems pretty common nowadays.

I think one of the district's "tricks" is to calculate the teacher to student ratio by including ancillary teachers (music, PE, art, etc.) in the total, even though they do not have a homeroom.
