The Common Core State Standards are a set of K-12 educational standards that are the result of a recent collective movement by state leaders to improve college and career readiness among high school graduates. The National Governors Association Center for Best Practices (the NGA Center) and the Council of Chief State School Officers (CCSSO) led the movement to create a new set of standards for determining high-school graduates’ preparedness for college and career tracks. A draft of the college and career standards was released in July 2009. From these standards, more detailed expectations for each K-12 grade level subsequently were developed, incorporating the best existing state standards, the input of educators and education leaders, and feedback from the public.The resulting Common Core State Standards have currently been finalized for grades K-12 in the subject areas of ELA/Literacy and Mathematics. Currently, 45 states have endorsed the Common Core State Standards and have at least some implementation efforts in place. Forty-four of these states have expressed a commitment to implementing assessments based on the new standards for the 2014-2015 school year in addition to replacing their previous individual standards. The movement toward adopting the Common Core State Standards represents a rare, cross-state consensus in United States education.
