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 due to political pressure from those who saw Common Core as infringing on local control, according to Abt Associates, a research and consulting firm. In Oklahoma, Gov. Mary Fallin signed a bill to repeal the standards in 2014 less than six months after defending them in a speech. She said Common Core had become too divisive.
Twenty-one other states have made or are making revisions - mostly minor ones - to the guidelines. Illinois kept the wording while changing the name. In April, North Dakota approved new guidelines "written by North Dakotans, for North Dakotans," but some educators said they were quite similar to Common Core. Earlier this month, New York moved to revise the standards after parents protested new tests aligned to Common Core, but much of the structure has been kept.
"The core of the Common Core remains in almost every state that adopted them," said Mike Petrilli, president of the conservative Thomas B. Fordham Institute.
Launched in 2010 by a bipartisan group of governors and state education chiefs, Common Core sought to bring scholastic standards to the same high level nationwide. The standards quickly became controversial when the Obama administration offered states federal dollars to nudge them to adopt it. States' rights activists cried foul, saying the effort undermined local control. Meanwhile, some teachers criticized the standards as confusing and out of synch with students' needs, while others feared that non-fiction would crowd out the works of Shakespeare.
