Most of the states that first endorsed the Common Core State Standards are still using them in some form, despite continued debate over whether they are improving student performance in reading and math.
Of the states that opted in after the standards were introduced in 2010—45 plus the District of Columbia—only eight have moved to repeal the standards, largely because of political pressure from those who saw the common core as infringing on local control, according to Abt Associates, a research and consulting firm.
Twenty-one other states have made or are making revisions, mostly minor ones, to the guidelines. Illinois, for instance, kept the wording while changing the name. And last month, New York moved to revise the standards after parents protested new tests aligned to the common core, but much of the structure has been kept.
