is common core the same in every state
Since 2010, forty-two (42) of the fifty U.S. states and the District of Columbia have been members of the Common Core State Standards Initiative, while Oklahoma, Texas, Virginia, Alaska, Nebraska, Indiana, and South Carolina did not adopt the initiative at a state level. Minnesota adopted the English Language Arts standards but not the Mathematics standards. Although starting as a fast trend, the curriculum lost momentum and found at least 12 states introducing legislation to prohibit implementation. Three states that initially adopted Common Core have since decided to repeal or replace it: Indiana, Oklahoma, and South Carolina.
