Illinois, I've only heard of a few news stories. Walkouts in Normal, Waukegan Superintendent against testing and CPS first looking to opt out of online testing and then doing an about face.
I was a teacher. The majority of my friends still teach and this isn't even a blip on any of the districts they teach in radar. Some are title 1 some are not. I know multiple CPS teachers. My CPS friends say the opt out rate is the same in their school ss when ISAT was being administered and most of the backlash is due to technology issues so they went to paper testing. I don't think that means there aren't opt out movements here, but they aren't anything like in NY and certainly aren't getting much publicity. Not one of my teacher friends is opting out their child and while everyone dislikes the number of tests nobody I know dislikes CC or feels PARCC is inappropriate only unnecessarily long.
