They do want us to include more non-fiction, but they don’t mandate what. They recommend essays by the Founding Fathers and gave us an assessment featuring an essay by Frederick Douglass about how learning to read was essential to him, and the little white boys who lived near the docks teaching him to read in exchange for bread. There was nothing in it a conservative would object to. It was awesome, actually. But they don’t mandate or even steer toward PC so far.
My understanding was that half of the reading in English is now supposed to be nonfiction, varied by grade.
If you’ve no longer a state-imposed curriculum, that’s of course very good. But in most states the districts are buying common core-compliant texts that are full of propaganda disguised as objective science and technology readings.
