Hi revmom,
It looks like we're seeing similar things. What grade level math is your accelerated DD in? We've got a meeting to discuss my daughter's placement on Feb 8. She's in 6th grade math as a 4th grader. Under the previous sequence (something we have in writing from the school...) she was to take pre-algebra next year. Now the plan appears to be that she take Common Core 7, the CC8, then finally algebra in 7th grade.
That isn't a disaster for DD, but sounds long, drawn out, and dull. I will be advocating strongly for DD to retain her gifted cohort in CC7 if this happens. However, I'm starting to catch wind that they'll want her in CC6 next year. That will be a disaster, and I'm taking extended steps to establish why that's inappropriate.
Check the CC standards online, and there are transition guides in there for transitioning into the CC standards, and no where does it say that kids should be placed back a year. There's no justification to undo accelerations.
I'm also reading through the state's requirements and guidelines on retention, since if you make my kid repeat a year, that's a retention...
I started a sister thread to this one about the definition of "rigor." Yes, rigor mortis is what comes to my mind as well.
