But as you can see, the change involved moving Algebra 1 from eight grade to ninth grade. Withholding this fact is pretty egregious in my opinion.
I tried looking for the other numbers she mentions by following her links, but the links she provided didn't contain those numbers. And the pdf I linked here wasn't provided by her, in fact not a single one of the numbers she used were supported by her links. I'd guess that the other numbers have similar problems as this one, but I can't know since she didn't provide a way for me to see where those numbers came from.
About the conflict between her and the others, it is hard to know who is right or not so I don't know. But judging by this opinion piece she cares more about her agenda than actual truth.
