I kept hearing the same phrase used over and over again about the Common Core standards: don’t complain, the train is leaving the station, and you don’t want to be left behind. It is inevitable. Then one of the readers of the blog, noting this cliche, wrote, “I didn’t know the train was IN the station, how could it be leaving?”

At some point, as the volume of complaints got louder, and as states announced they were dropping the standards or the tests or both, the narrative began to shift. That sense of inevitability disappeared, and the nation seemed to go into a period of watching to see which state would pull out next.

Fortunately, Mercedes Schneider has been keeping count. Here is her latest summary of the slow dissolution of the Common Core.

In case you didn’t know it, Schneider just spent this summer (which is barely half over) writing a book about the Common Core. We will wait to hear more about publisher and publication date. Let’s just say she may be the fastest, most prolific writer in our field.
