My read on the newly announced work and feedback teams for Common Core English Language Arts standards is that this doesn't look like a group of people who will pay much attention the College- and Career-Readiness Standards. It is too broad a group for that. If you limited the scope of the preceding curriculum to the CCRS, these folks would revolt and demand additions to the CCRS, which would throw everything off schedule.
Also, they're still calling them "English Language Arts" instead of "Reading, Writing, Listening and Speaking." And I seem to recall that they were going to start at the lower grade levels rather than working backwards.
So my prediction is that we'll get some kind of national graduation test based on CCRS, but a more conventional set of K-12 standards, which, frankly, would be an improvement in this case.
