Our district is rolling out the common core math this year, and I think language arts and social studies next year.
Oh, your people are talking about rigor too. Ours never define what rigor is, but they say it a lot. The meetings for parents about the new math curriculum basically boiled down to the presenters saying "rigor rigor rigor" until the word lost all meaning. It got funny, but also weird and unconvincing.
According to the College Board, which collects fees for AP tests taken, a sign of "increased rigor" is more students taking AP exams, as they explain at
