The Core Issue

I had a meeting recently where the coordinator for one of the departments in our school stated outright, "We're not tested on PARCC." Now, I have to admit that I have been working on the Common Core for what's coming up on three years, but I do not know everything about it.

But, my understanding is that we ALL teach literacy in our content areas...we are ALL responsible for what happens when the PARCC exam rolls out next year. While there is not a Social Studies or Science or Art section on the Common Core, aren't we ALL responsible for teaching reading and writing?

Why is this message not getting across to everyone?
